Pros: Quiet. Large. I got these to store large movie files, each ranging from 4-10GB a piece. I do not run my OS from them. Super easy to format in Win 7 64 Disk Management and then lock and load! I have them set to sleep when not in use. No crashing, etc. I got them along with the silverstone HDD 5.25 Bay box that holds 4 drives. Works perfect.

Cons: Nothin'

Overall Review: I've never had a dead HDD from NewEgg.

Pros: Love Love LOVE this thing. It is EXACTLY what I was looking for. I have the Awesome Thermaltake Level 10 GT case from Newegg, for over a year now, and I was expanding my HDD capacity and looking for something like this device. I couldn't have dreamed one up better; it holds four 3.5 or 2.5" HDDs in a sturdy well cooled box. The box looks awesome from the outside, and what's even better, while it holds 4 HDD's, it only takes up three 5.25" bays. Hence, in my standard 4 5.25" bay area on my PC case, I have this device and a DVD writer. It just looks and works great. Buy a whole bunch.

Cons: Not. A. Thing.

Overall Review: I ran out of thoughts.
