Conclusion

Western Digital WD1200JB is the first 120GB disk drive that arrived in our labs. The drive has an 8MB buffer and according to Western Digital, will increase the drive's performance especially when it is used at Servers, where lot of read/write are occurred at the same time.

As our test results showed, the drive is very fast but it didn't perform better than the 40GB disks at the IPEAK Server test. Intel's IPEAK "Server" test contains lot of write and read operations on the disk. WD1200JB has high seek times (13ms) for both reading/writing tasks. This could be an explanation for the low performance of the drive in this test. SCSI drives are preferred for servers; due to their very low seek times (under 5ms).

Most users who need such a high capacity disk will use it at normal modes, and for this use the WD1200JB will be a good solution. The drive is very fast and the 8MB of buffer does help and delivers the maximum performance at this category. The price of the drive is around 379$, which is high enough but it we believe it is worthy :-)
