The Caviar SE16 WD7500AAKS is the top of the line high capacity (750 GB) drive from Western Digital. The drive uses a four platter desing with 16MB of buffer, which is the norm in this segment. Like other Western Digital drives, the WD7500AAKS implements SecurePark and ItelliSeek for improved shock tolerance in powered off mode and improved power management respectively.
The cost per GB comes to about $0.40 which is good enough. The Price of $299 is a little too high for those who are looking to update specious secondary drive, though its a decent purchase as a primary hard drive.
We have compared this drive and the Segate Barracuda ST3750640AS (750 GB). The Caviar SE16 WD7500AAKS is a clear winner.
