I have 4 of these configured in a RAID 5. Going on a month and they are plugging away just as expected. The green series from WD definitely saves on power which is great in terms of heat and money.

I purchased two of these on sale for around $160 each. Good ratio price/GB. Plenty of storage space. Not suitable for Video encoding jobs since it's slow, but it's good for anything else.

Good quality; Good ratio price/GB

A bit noisy; Slow

Works as advertised. I chose the WD green because of higher reliability. Warranty is 2 years. I use as an external backup HDD for my MacBook Air connected via a USB dual docking station by Startech.

Will buy again

This drive stores and loads all of my applications and games. I see a lot of people talk about game load times on SSD's, but the performance of this drive is such that I've never thought about putting all my games on a SSD to squeeze out a half second faster load times.

This drive has lots of storage and so far has worked flawlessly. Since it is only a 5400 rpm drive it would be quite slow a a main hard drive but is awesome for mass storage. I hope to purchase one more to help with backups.

SO FAR NO PROBLEMS. WILL UPDATE LATER...

2 years and 1 month since purchase and the drive has just failed with bad sectors. Not impressed.

Great R/W speeds. Bought 3, no issues 10/10 will buy more when the wallet allows

This product lasted 3 months before conking out on me I attempted to get a return merchandise authorization (RMA) and found out that the product warranty is void. According to Western digital's website, the product with this serial number should have been inside a MyBook.

I have bad luck with WD drives. These are supposed to be quiet drives so I gave it a try, but the vibration is high enough to shake the whole case. It'd be fine for office use, but not for a quiet PC.

Large capacity; inexpensive; works well enough

Vibration and noise
