Kinda loud but not too much care about itMoreover, the performance is most important thing, of course, WD wont let you regretly when you purchase this HDMr

Overall love the performance of this drive and would recommend in a heartbeat.

I added this drive to my Mac Pro Workstation and the performance is outstanding.

Downtime is not an option!This drive offers the best performance and reliability compared to any other HD on the market by far!

For the storage space you get, the reliability, and rock solid performance, you cannot go wrong

Great performance and value.

Significant performance improvement with this drive

This is a very quick hard drive -- positioned (performance-wise) between an SSD on one side and a standard 7,200 rpm SATA III on the other.

Great performance and value!You can't go wrong with Western Digital frankly.

Best performance for local storage

This is a very quick hard drive -- positioned (performance-wise) between an SSD on one side and a standard 7,200 rpm SATA III on the other.

Moreover, (3) VR's will saturate your SATA III bus, so more drives won't improve your performance.

their performance is really good especially using RAID

You can get pretty insane performance if you RAID these together

Would recommend this to anyone who wants good performance and decent storage at an affordable price.

Performance is superb, operation wise, they are way way quieter than the original Raptors

Greatly improved performance all around

WD VelociRaptor is excelent, this performance is cool with 10.000 rpm and 200 Mb/s, in my case I buy an used HD, the only bad is my hd had 20.000 hours to work

performance is great

works as it is supposed to

This hard drive is super fast not as a

Even for non gamers, I don't think I have ever seen any Office product open as fast as with this drive

A bit of noise ramping up, but not as bad as
