Personally, I would rather have the unnoticeably slower speed since it gives me all of these benefits

Good speed and temp

Speed is pretty decent for a Green model.

Really good drive, nice speed and really quite under writing/reading circumstances

Runs cool and virtually silent, plenty speed for data storage, big improvement over older and failing WD Green Caviar.

and I copy files up to 220 MB/s!!!. Good price, good size and excellent speed.

Nice size and speed for the price but the noisiest hard drive I've ever owned; its white noise easily over powers cooling fans and even the high speed DVD ROM

Knowing that I just needed a mass storage, speed wasn't a concern.

All you can expect for a HD from WD, using it as a storage disk for media in a home computer works really great, nice temperatures, good transfer speed, great for home use.

I would recommend this HDD as it still puts out great transfer speeds and has been very dependable so far.

This HDD has slow speeds

High capacity, high speed, easy to install.

It has good transfer speeds, and hasn't died out considering the amount of information transfers I've done on it since November 15, 2014 when I originally purchased it

That way I could switch to a faster speed when the power-saving, heat-reducing properties aren't needed (a sort of hard drive overclock)

Pretty consistent write speeds of 95-110MB/s which is better than I was expecting

Nice size and speed for the price but the noisiest hard drive I've ever owned; its white noise easily over powers cooling fans and even the high speed DVD ROM

The RAID worked fine for a couple hours then I started experiencing extremely slow write speeds while migrating my data over (nearly 2TB at the moment).

Runs cool and virtually silent, plenty speed for data storage, big improvement over older and failing WD Green Caviar.

The speed of this drive is pretty decent and works great for me for my bulk storage

Works at decent speed and even survived 4 power outages

Drive works fine, but the slow read speed is VERY noticeable

nice speeds...

It has run great, good speeds, no hiccups for almost a year now

However, to list the slow speed as a con is only a con if you truly require a drive for very fast applications, or are using it for a RAID setup

Shipped at reasonable speed and works fine.

Good speed, high capacity, no negatives

Cheap and regular speed shipping

Excellent low price storage for media and data that is not speed sensitive.

I have been buying wd drives for 15 years and this is no exception, quiet, cool, speeds 150 mbps on older machine, use it for audio and video editing, highly recommend!

The reason I bought this hard drive specifically (even though is considered "old") was because I have two more just like this one that have serve me well for a few years already, never a problem, speed is good, overall I don't have a complain about it

I don't use it for things where I need super-fast speeds, so I can't speak to benchmarks or the like, but it's worked very well for my needs, and I've had no issues with it thus far
