The WD400AB is a 5400RPM IDE hard disk drive, which has a capacity of 40GB. The WD400AB was the third-fastest IDE drive. It scored slightly over 10,000 in Winbench Business Disk and a bit over 20,000 in Winbench High-End Disk. It has three 13GB surfaces and only three heads (one of the two platters has an unused surface). Because the drive was running at only 5400RPMs and not any faster they were able to have higher density surfaces. The WD400AB has a 2MB buffer like its faster brother, the 7200RPM WD400BB. This also means that it has a higher average seek time then the WD400BB. Its direct competitor is the Maxtor Diamond VL 40. The Maxtor was a little slower in all the tests but is $16 cheaper overall. But for an extra $16 it's worth going for the faster hard drive.
