Pros: Large size, good speed, better energy efficiency than most other hdds.

Cons: Built my own computer using two of these in a raid array, worked fine for a few months, then the slaved hdd failed bios, degrading the raid. WD sent a new one through their rma, but recently the other hdd failed the exact same way. Finally had both fail the other night, I have heard from several of my techy friends that the green series can be fickle. Looks like they were right.

Overall Review: I'll probably upgrade to the black series.
