Hitachi vs. Seagate 400 GB Hard Drive Comparison
 

So today we will review two of the biggest hard drives currently on the market. The first drive is the 400GB Hitachi Deskstar 7K400 which features five 80GB platters, 8MB of cache, a 7,200RPM rotation speed, and a 8.5ms average seek time. We will also look at the 400GB Seagate Barracuda 7200.8 which carries basically the same specifications as the Hitachi drive except that the Seagate has a 8ms average seek time rather than 8.5. Both the drives in this review use the SATA 1.5Gb/s interface. However, they are also available in PATA if needed.
