IBM DTLA-307030
I received a lot of emails from our readers complaining about the missing IBM and Maxtor drives in the recent hard drive reviews at Tom's Hardware Guide. Generally we don't leave out certain products intentionally. If some drives were missing so far, it's simply because they were unavailable to us for different reasons.
First of all I want to apologize that you had to wait until now for us to review IBM hard drives. I'm also expecting to receive the latest Maxtor drives rather soon.
IBM's Deskstar Family
Finally, we received a 30 GByte model of IBM's latest IDE Deskstar series, the 75GXP. The series is called DTLA and follows a tradition which goes back 11 drive generations. IBM launched their Deskstar family with two 540 MByte drives (one IDE, one SCSI) several years ago. Those drives ran at 4500 rpm and came with 96 kBytes cache.

All IBM drives are well known for their excellent reputation regarding performance and reliability.
