Great drive, no issues since install, plenty of space for my cameras...

Although the hard drive is good the xmarto security system is very disappointing.

3 terabyte drives have a terrible reputation of failure but so far so good with this WD Purple Surveillence hard drive.

Very easy to install hard drive more than enough backup now

It's a great performing drive

Drive seems to work fine.....

Be sure if you are getting a new hard drive for your surveillance system you get the correct drive

Great drive for security cameras

Very good hard drive.

It's a hard drive, works like it should!

This hard drive is the best for security camera systems

great drive for security system fast deliver

Since it's part of a multi-drive redundant array, I can't measure the speed of any one drive.

This drive was Dead on Arrival

Best drive I ever bought that is mechanical

This hard drive is BETTER than the one you might probably get when you buy an DVR system.

Worked great , used it for my 7400 NVR security system, I used it as an external hard drive to expand storage space

but, alas, it wasnt to be and its not the hard drives fault.

Hard Drive is six (6) months old on day delivered, reducing warranty by this same amount

This drive is very quiet

Noisy Drives!!!2 drives I have measure 40-44 db

I needed to upgrade my Tivo hard drive and after doing some research I decided on a Survelillance Drive as it is made for large video files and is made for fairly continuous operation

Turns out one of these hard drives

They aren't HD cameras so using this hard drive gets me over a month of storage before having to make room for new recordings

Of my past 30 consumer grade hard drives, all of my WD drives lasted until I decided to take them out of service for larger drives.

Upgraded the drive in my surveillance system with this

The best hard drive for surveillance

I installed this hard drive in my Swann 8 camera security system as a replacement to a 3.5 inch WD Green drive

but I had enough dead drives sitting around to acquire it from them.

Recommend this for people who want to run a hard drive 24/7.

Great hard drive no problems with any I have installed yet

Flawless recording with our Dreamliner unit and easy installation of the hard drive into the unit

No unusual noisesand no reboots for hard drive issues

I appreciate the efforts they've made with the packaging so far, but as it stands now, their WD name is riding on the assumption that mail order companies know how to package their hard drives safely

Task Manager in Windows 8.1 shows the drive is barely working, never exceeding 1% utilization, and this is after filling the drive probably 20 times over to the point it was highly fragmented.

Overall, a great drive from a reputable hard drive manufacturer.

Works... isn't that what all hard drives need to do

This is the best Hard Drive if you have a security camera system.

Bought this to replace hard drive in my CCTV's DVR and am quite happy with it

I ordered this hard drive as recommended by Z Modo

Their Purple drives are for use in surveillance systems - they will work in a PC, but not optimal

and I have never had any hint of an issue with this hard drive

Great hard drives... so far.

After having tested a cheaper Hitachi drive that I had to return because it made loud noises and got very hot, I was pleasantly surprised at how quiet this WD drive really is

Well, ironically, this WD hard drive wasnt recognized by a legacy Dahua DVR, so any attempt on my part to review this product is fruitless

6TB for extending my Directv HR54 internal hard drive of 1tb to this 6tb

Installed easily and works like a hard drive is suppose to.

Overall, the drive has no issues or bad sectors yet, runs far quieter than my WD Black and has been great to me thus far, all while being affordable.

I use both the WD Purple 2TB and 3TB hard drives in several different security systems and believe they are one of the best surveillance system hard drives available from any manufacturer

It works great, fast, and runs incredibility cool as compared to other hard drives

Great drives.

Both drives failed out of the box

Well the hard drive I recieved was

Ordered this to replace a hard drive in a surveillance DVR

I would definitely recommend this disk drive to anyone installing their own CCTV system.

excellent drive for our dvr, good price too.

My DVR holds up to 8 hard drives and I am going to be putting 8 of these in it.

I have had other WD hard drives with no

I have not had any problems with the WD Hard drive,I use it for camera back up and seems to be very dependable!

THis drive is great!!

Thanks fellas now my hard drive is sufficient

These are very nice drives

I use this in a drive array to serve media (TV and video) within my home, so the ultimate measure of a hard drive for me is reliability.

Excellent Hard drive, quiet, working as expected.

Excellent Hard drive, quiet, working as expected.

Amazon combined my hard drive order with a separate order of books without my consent.

If you have a security system you will see a huge difference with this Hard Drive over all the others.

Installed easily and system had no issues recognizing the drive and formatting it to it's specifications

Truthfully, it's really hard to review a hard drive; what can you say?

In other words, it gives hard drives a pretty good workout.

I purchased it mainly because it is quiet, and I built an HTPC, so I didn't want the hard drive spinning to interfere with the audio in the movie.

This is accomplished through the "ATA Streaming Command Set."The slow 5400 RPM rotation means that this Purple drive is very quiet (this is its best feature, if you're using it for a Home Theater system and need a super quiet environment) and it generates less heat than a 7200 RPM drive in continuous operation

I will update my review after a while of using the hard drive.

I found this setup on several online forums along with numerous recommendation for the Western Digital Red and Purple hard drives

Love these drives!

I previously used a couple old hard drives I had laying around

This is the correct hard drive for a security system

Hard drive constantly craps out and will not allow recording

Very nice drive - and the recording seemed to improve along with playback after installing this version

Only 30 days!We can accept a drive supplier that raves about how durable their drives are but at the same time not accept the return an obvious dud drive

I made an uninformed initial purchase of a WD Blue Hard Drive for my surveillance DVR, it would intermittently work, maybe 10% of the time

Customer bought a dvr from another company thinking it came WITH a hard drive

I even suspected the Seagate Enterprise drive that was originally supplied with the unit by my retailer, so they elected to swap it out for a Western Digital Green AV-GP drive, which at that time was supposed to be the latest and greatest for surveillance systems, but that didn't help either

works great in my lorex security system, the old hard drive died. and had to replace it quick.

I have two NVRs and this drive was giving me a problem

For a hard drive that is designed to run in a DVR, it should last longer.

Easy to install, matches the existing drive in my NVR doubling my capacity.

One bad new drive is just bad luck

Im not sure I would blame the drive though

Great drives for our security surveillance.

Bought a MyCloud server to use with external hard drives

Works best in my surveillance system over every other hard drive I tried.

Awesome Drive.

Excellent hard drive, tremendous performance.

I have a 6 camera system and it only came with a 1TB hard drive

Hard drive is work fine

It's extremely quiet and runs very cool, hardly any temperature rise at all, unlike other hard drives I've owned

This drive worked as it should in my security DVR for ONLY TWO YEARS

Data is data and nothing more than 0's and 1's, the hard drive couldn't care less if it's video or docs as long as it can handle enough throughput for your application.

I’ll be more careful on buying a reliable hard drive.

Excellent drives for TiVo hardware upgrades.

It returns "registration unsuccessful" messages while trying to setup the return of a defective hard drive using Safari broker on a Mac.

They immediately sent me a replacement and shipping label to return the bad drive

Been using this for several months now in a security DVR excellent hard drive 24/7 record flawlessly

the hard drive does not work on hardware damage was detected

The best hard drive for cctv system!

Most external hard drives are not designed to run for long periods of time but the WD Purple Drives are designed to run 24/7 and it also handles video and multiple streams of video better than the standard external hard drives

A 5400 RPM Western Digital Green drive with twice the capacity is available for about the same amount of money

As usual, Western Digital designed this drive for constant sustained write abuse

Great hard drive for the price!

best hard drive for surveillance and every day computers

Great hard drive.

I got this drive because it does not suffer from the Idle3 Timer Issue that some other WD drives suffer from

, "Time Limited Error Recovery - where the hard drive assumes it is part of an array, assumes there is redundancy, and is not afraid to quickly tell the host controller that it just can't complete

After you install the drive, you can not wall mount the NCR since the hard drive uses the same mounting holes.

Yes excellent drive; however customer did not find it to be quite enough.

Supports up to eight drives..

very happy with this hard drive with plenty of room to store all my recorded camera footage

If I install this into a hard drive bay for backup purposes, and connect via USB3, it works like a charm

Good hard drive

Update: Had this hard drive for recording surveillance video for over two years, running 24/7.

powerful and great hard drive

Love these drives

This hard drive worked excellent in my Bolide DVR

Western Digital is a good brand for hard drives.

It helped that the modem I installed the hard drive in recommended this particular product

I need to send this back because it isn't the write hard drive

I bought this drive and put it in the Seagate box and it works great!

Awesome drive at great price

Holding up fine in surveillance DVR that killed several other type drives.

For the price these drives are awesome

So, if you are using this as a data, streaming music, video source, this is the perfect drive.

Great drive for my NVR runs cool and quiet

This hard drive worked excellent in my Bolide DVR

powerful and great hard drive

Happy with this product and will order it again from this company if I need a bigger hard drive

The drives just work without any issues year after year.

Good hard drive

Great price, good drive!

Hard drive would get a better review, but it didn't even last a full 4 months.

Some people think you can put a regular hard drive in a surveillance system and when it crashes they blame the hard drive

Thanks for agreeing to send me a USED, previously DEFECTIVE hard drive to replace the one I purchased NEW at full price 6 months ago

Western Digital purple the only hard drive to use for security camera systems

I am fairly confident, however, that the drive was damaged during shipping, and that it probably was not defective from the manufacturer.

I use the 2TB for AHD/DVR/NVR security systems with SATA II (maximum HD capacity allowed is 2TB) hard drive systems for 720p or 1080p resolutions with 8 camera channels

Great hard drive.

Great hard drive for the price!

I figured this was straining the drive more so than if I just let it run without defragmentationThe drive is also very quiet

Great big huge drives

The WD Purple hard drives offer low power consumption and advanced performance features usually only reserved for enterprise-level storage and are optimized to withstand the demands of always-on digital PVR, DVR and NVR recording environments

Good solid drive.

Been using this for several months now in a security DVR excellent hard drive 24/7 record flawlessly

Quality hard drive for video surveillance storage needs

Exactly a year later, the cameras started to flicker, and when I turned off the hard drive to reboot, jit did not come back on - it said LOADING .... and then quit.

I was refunded within 2 days of them recieving defective drive.

I'm glad I spent the few extra bucks and went with the PURPLE one because I was told by my IT guy that the PURPLE WD Hard Drives are intended for security camera hard drives, since they run 24/7

Hard drive is very cool running and quiet, perfect for security cameras and NAS system (I use it for both)

I’ll be more careful on buying a reliable hard drive.

I also believe I got a better drive

This is one loud hard drive , I installed it in a DVR security system , I don't think I've ever heard a hard drive make that much noise .

However, using the less-expensive green drives would incur a notable performance decrease

Hard drive is work fine

But for some reason, if I install this internally, it seems to bother the primary drive and cause issues

I had specifically placed the orders separately, about 4 days apart, so that the hard drive would ship all by itself.

Excellent hard drive, tremendous performance.

I bought this 3TB hard drive for one of our clients' DVR systems.

i good 10 secondsswapped out drives used my "normal" drive on same cameras and working just fine

It's a WD hard drive, what more is there to say.

haven't been able to use this hard drive yet because I installed it in the security system that came in defective plug

One bad new drive is just bad luck

Best Hard Drive for DVRs & Surveillance applications.

Serves as an excellent DirecTV external eSATA drive

Worked perfectly!Directv Customers: I found out the hard way when you hook up an external hard drive to your receiver, you lose not only lose your recorded shows/movies on the internal drive but also your list of shows/movies you want to record

works great in my lorex security system, the old hard drive died. and had to replace it quick.

Best drive for Digital recorders and well priced

Very durable drive.

Great drive -- Works well in my security camera NVR.

My setup so far is only 1 camera, so I cant really comment on performance as any hard drive can support 1 camera

This is the correct hard drive for a security system

Expensive but looks to be reliable, high quality drives

After hours of troubleshooting I found out we needed to buy and install an internal hard drive

I just love their drives

However, one of the drives failed error surface scan and erase write tests (HD Tune software) when it was received, so it had to be returned.

I purchased this hard drive for a security surveillance system

This drive's a winner.

Make sure you scan your hard drives when they're delivered!!

Twice now within the past month the drive has failed

This hard drive has outlasted every other drive I have bought.

Excellent drives

cuz it started buzzing real loud for about 10mins, but the nvr was just automatically formatting the hard drive.

Excellent Hard drive, quiet, working as expected.

2 Stars for the fact that it failed - i know all hard drives will eventually fail but 2 years isn't very long but glad its under warranty!Update 1/20/17

Thanks fellas now my hard drive is sufficient

Bought this drive for my Security camera system, so far it works great with no issues.

the best hard drive for network video recorders and surveillance dvrs .

A typical desktop hard drive will try up to ten times to write to a block, and if it fails, it will map to an alternate

I installed this into my surveillance system DVR and the hard drive has been working great.

This is a terrific drive.

I used the WD Purple 2tb hard drive on CCTV security system and is doing well.

Well the hard drive I recieved was

During the 15 hour test of constant writing and reading, the drive was only slightly warm to the touch.

I use both the WD Purple 2TB and 3TB hard drives in several different security systems and believe they are one of the best surveillance system hard drives available from any manufacturer

Installed easily and works like a hard drive is suppose to.

I ran a diagnostic test for15 hours that writes and reads to the entire hard drive

Well, ironically, this WD hard drive wasnt recognized by a legacy Dahua DVR, so any attempt on my part to review this product is fruitless

Excellent drive,used 4 our 5 cctv cams

I went from a 500 gb hard drive that came with my dvr security system that recorded only 3 days of continuous 24:7 HD 1080i to hopefully about 3 weeks of recording

Great hard drives... so far.

I am in the home automation business and truly appreciate a drive specifically made for the continuous use in security camera equipment

The hard drive was defective as noted by the repeated message of failure and reported as abnormal received after repeated attempts to instal the hard drive

Overall, a great drive from a reputable hard drive manufacturer.

Quiet drive, hope it runs for a long time!

Purchased this for my new IP security camera system and opted to save some money and install my own hard drive instead of having the distributor install it.

This drive works very well in my TiVo Roamio

This drive works very well in my TiVo Roamio

yes as a matter of fact it is a hard drive

The drive is quiet and fast.

TO 3.5 Inch IDE or SATA/SATA II Aluminum Hard Drive Enclosure Case with Cooling Fan (EC-UEIS7) and StarTech

Great hard drive no problems with any I have installed yet

Now, having said that, I bought this drive because it was recommended by Amazon when I put a NVR (Network Video Recorder) in my cart.

but I had enough dead drives sitting around to acquire it from them.

Windows and everything is loaded on this HD as I don't have a solid state drive on that computer.

I have had very bad experiences with getting a brand new larger drive, consolidating my media files, only to have the new drive to fail in a short time, losing media that unfortunately was not backed up yet.

If you buy a system without a hard drive this is the one to get

You need a hard drive?

It's a hard drive, it's Western Digital, it's purple

Reliable drive

What I will say is that Western Digital is the only hard drive I will use for my computer builds

I've tried defragmenting the drive before, but when doing so the process took a day while thrashing the drive at 100% utilization.

Please inform that U need power supply support for a 3.5" desktop drive to prepare drive in "win drive management"!

Why do it this way instead of buying a standard external hard drive

Was determined hard drive faliure

Then after installing it, and more hours of troubleshooting, tech support informed me that it won't recognize it on the network properly unless I purchase and install a 2nd hard drive

TUrns out the hard drive I receive is faulty and has been the entire time I have had it

Use the hard drives all the time.

This hard drive is BETTER than the one you might probably get when you buy an DVR system.

Worked great , used it for my 7400 NVR security system, I used it as an external hard drive to expand storage space

The drive is quiet and has been dependable.

I also highly recommend a RAID 10 configuration with a good Adaptec (or other reputable brand) RAID controller card to ensure that you can write the video streams to the hard drive fast enough when you have multiple surveillance cameras and/or high definition resolution streams.

Love these WD Purple drives

This hard drive is performing as originally advertised.

I upgraded the from the 1 TB hard drive to this 3TB drive

In case you're wondering why CPU usage dropped, it's because my system was being bottlenecked by the hard drive and it was trying to write to a drive that couldn't keep up with the task thus causing higher than normal CPU usage

The original drive failed after three years, which was a bit disappointing, but hopefully this one will last longer.

I have installed the drive and it works perfectly.

This hard drive is the best for security camera systems

It's a hard drive, works like it should!

Did you know that Western Digital manufactures over 60% of the read-write heads and chips for all hard drives in the world?

Very good hard drive.

Seems like a great drive so far, fast and reliable but time will tell.

I got this to increase my recording capacity for my Directv DVR HR44/500 along with the Anker USB 3.0 & eSATA to SATA External Hard Drive Docking Station

1st Hard drive arrived DOA

Be sure if you are getting a new hard drive for your surveillance system you get the correct drive

My 2014 LaView 500GB hard drive finally bit the dust, so instead of changing the entire system I decided just to change the hd and up graded to a

I don’t have any empirical data for noise, but the hard drive activity never became audible above the hum of the CPU fan in my desktop

I then took the WD hard drive and put it inside a USB SATA enclosure and then inside a computer

Although the hard drive is good the xmarto security system is very disappointing.

This includes 5 x 1080p HD camera's and 3 x 480p cameras all delivering video and sound 24/7 to this hard drive

I've owned a lot of hard drives over the years

In a nutshell, the hard drive firmware on this drive will prioritize the timeliness of video streams instead of trying to make sure that the data is absolutely correct (which can lead to long pauses and dropped

Would also make a great drive for storing HDTV captures from a regular DVR or general data backup or storage

You must use a different hard drive for video installations

If you check the Western Digital site you can see which drives are best for which use

well i have this hard drive for 1

right price points and item is shipped promptly with proper packaging to protect the hard drive disk from moving.

Perfect hard drive for my computer!

I will NO LONGER purchase WD hard drives from Amazon

I have experienced bad drives in the last shipment and they are not eligable for return

Great hard drive for surveillance

Great drive for my Zmodo DVR.

Great drive.

These are excellent for my DVR's and once I buy one do not have to worry about hard drive failure, which is a huge plus considering I use these for a DVR, and it is crucial that I have camera footage of the last 10 or so days at all times.

Hard drive didn't work 😡

I like WD hard drives and have not had any trouble so far with them.

Hard drive has been working in our security dvr for months now without any issues

I have had tweo shop lifters walk away scott free because of this lousy hard drive

This is a reliable drive, and it's the one you need to purchase if you plan on recording security cameras.

This is the perfect drive for use inside a DVR/ SVR surveillance system.

Definitely better than my old hard drive.

Ran a battery of hard drive tests before installing into my NVR and they all came back 100% good

The internal hard drive content DOES NOT GET DELETED when you install an external hard drive

I'm using this drive in a Thermaltake Max 5 G active cooling Hard Drive Enclosure

Notice not to buy SSD hard drives for DVRs as they will wear our quickly

Great hard drive

Good Hard Drive

It hasn't been long enough for me to say confidently that this drive has solved my problems, but I'm very hopeful.

I have been using this Hard drive for my security system at home and it runs 24/7 without any issues

I rebooted my NVR and it showed this drive dead and thank

The drive is quiet and has been running 24-7 for about a week now with no problems.

This is another quality WD product that I installed as an upgrade to my CCTV, and the results are very impressive with virtually no visible video frame drops thanks to the "AllFrame technology" that were present with my legacy "Green" Hard Drive.

the best drive for NVR DVR recording system that requires constant re-writing

Purple 4GB Hard Drive for a PC dedicated to my surveillance system

It was easy to install this hard drive into our security camera system

just what I had order and came fast to me also,Great price and great hard drive also..

good drive owned a few of these for security NVR's

Running for months and no problem at all ,great hard drive , never use wd green our other type of drives for cctv ,always use those , I was using a wd green drive for my cctv system ,bad idea

Works excellent , no problems, been using these drives for years now

Hard drive works fine.

This drive worked flawlessly, and I am very pleased.

This hard drive is great.

tb hard drivesmart status shows the drive is good no bad

With any CCTV security system, the hard drive is one of the most critical system parts and must provide dependable service (this is one part you do not want to scrimp on or depend of the typical computer type hard drive)

This hard drive worked excellent in my Bolide DVR

But I can't use these hard drives if they're going to be unreliable.

Not much you can say about a hard drive.

great hard drive

This drive resolved an issue I was having on my media pc which runs my 6 security IP cameras 24/7 with motion, and, my 4 tuner Centon Cable card

Can't go wrong with WD hard drives

Drive is very quiet and can't hear it spinning.

I get allot of traffic around my house on a daily basis and I got about a month of recording time on this Hard Drive.

Plugged it in and formatted the drive and works great

Installed alongside the original Hard Drive which was also a WD Purple, and they worked well together

Installed this in my TiVo Roamio to replace a failing 1tb stock drive

WD drives never disappoint IMO

Both times the drive wouldn’t even power where other drives would just fine

Worked perfectly - change out with the old hard drive was very simple and easy to do

This hard drive failed within 3 months and unfortunately there is no alert when this happens.

So far this has been a great hard drive.

This drive is very cool for such a high-performing 7200 RPM drive

If you are building a cctv or security camera system, this is the hard drive you want

Great drives.

I use my drives for streaming movie and TV show files and the way streaming works is that it buffers a minute or two of the movie then lets the drive go idle

The perfect hard drive for the Sannce Cameras system, Easy installation and operation!

Highly recommend this drive for anyone building a DIY Home Security DVR setup or replacing a hard drive in a pre-built DVR.

WD20PURXA quality hard drive with plenty of storage space at a good price.

Hard Drive works great, fits my xmarto dvr system.

The install was a breeze, just slide the WD Purple hard drive into the Anker or the docking station of your choosing, connect the eSATA cable from the Anker/docking station to the Directv DVR eSATA port (make sure DVR is turned off by unplugging it), turn on the Anker/docking station, then plug in and turn on the Directv DVR

This is an OEM hard drive, not the retail one

Hard Drive works great, fits my xmarto dvr system.

I would highly recommend this HD to anyone looking to use it in a DVR, works flawlessly unlike a traditional hard drive.

Highly recommend this drive for anyone building a DIY Home Security DVR setup or replacing a hard drive in a pre-built DVR.

The perfect hard drive for the Sannce Cameras system, Easy installation and operation!

Normally a pretty reliable brand/drive

I hope they last longer than the regular hard drives.

Better or worse than a regular hard drive, dunno.

Slower than you'd see on a traditional drive, keeping in mind this is a 5400rpm drive, but still well worth it

The performance loss is not significant considering that they outperform 7200 RPM drives from just a few years earlier

I would recommend this WD Purple drive to others

Have always had good luck with WD's hard drives, No disappointments

This time they promised a new drive and return shipping

I don't recommend the purple drives.

Also the internal DVR hard drive can not be seen or used while you have the external drive connected to the DVR

So far this has been a great hard drive.

Lesson learned: don't use a single bay drive for backup and don't use Western Digital Purple hard drives.

The drive was easy to install, and holds surveillance video for over a month.

Excellent surveillance drive (4tb), video playback seems smoother than my genaric drive received with my NVR

I used to have hard drives that failed after a year or a couple months but these work great.

Only thing else would it could be is the new hard drive

Price, seller and item are the best, drive received in 7 days from payment!!!!

Drive runs very cool 24/7 in my security DVR system and has a 3 year

4 hard drives purchased - been running without issues for 60 days+

great hard drive

This hard drive is meant for 24/7 surveillance DVR's

This hard drive is great.

Running for months and no problem at all ,great hard drive , never use wd green our other type of drives for cctv ,always use those , I was using a wd green drive for my cctv system ,bad idea

Best drive for surveillance!

just what I had order and came fast to me also,Great price and great hard drive also..

The drive works OK but my Directv DVR stutters fairly often (every 30-60 minutes) with this

Maybe after the logo on your hard drive where it says

I went ahead and ordered a 4TB WD Purple drive to try to rule out the hard drive being my issue one last time, and low and behold, that's exactly what the issue was all along

This is another quality WD product that I installed as an upgrade to my CCTV, and the results are very impressive with virtually no visible video frame drops thanks to the "AllFrame technology" that were present with my legacy "Green" Hard Drive.

Have it for about 6 months now and still running good in my nvr surveillance system which I added to the existing 1 terabyte hard drive.

I rebooted my NVR and it showed this drive dead and thank

This drive has been running more than a year now and the S.M.A.R.T. data shows an absolutely perfect drive

Good Hard Drive

Great hard drive

Reliable drives

but when I put in a different hard drive the NVR worked fine

Very Very nice surveillance hard drive, its quite and on my system which has 4 cameras I get 2+months of record time

This Hard Drive died in less than a year

I'm using this drive in a Thermaltake Max 5 G active cooling Hard Drive Enclosure

WD Purple hard drives are all i will buy

Most systems with an optional hard drive do not supply mounting screws

As always WD puts out a superior drive I always use WD drives.

I highly recommend this drive for anyone with a surveillance system, hands down.

Hard drive has been working in our security dvr for months now without any issues

I like WD hard drives and have not had any trouble so far with them.

Attempts to replace an older WD 2TB green drive in a Tivo Premiere though failed so far

but it's far better than any standard eSATA external hard drive you could buy in this price range

Great hard drive for surveillance

we realized the drive was a dud.

Both types of hard drives use the same error correction code (ECC) to protect the data

You need determine your needs before you purchase a hard drive

Perfect hard drive for my computer!

i good 10 secondsswapped out drives used my "normal" drive on same cameras and working just fine
