WickedPC heeft een review gebouwd van de 22Gig dikke 22GXP drive van IBM. Het ding draait op 7200rpm, ondersteund ATA/66 en heeft een vette cache van 2Meg:
The benchmarks pleased me. The 22GXP hard drive is faster bit a significant margin over the 8.4GB 5400RPM drive. Our only complaint is that the CPU usage almost doubled. Then again, that's what IDE is supposed to do, so no really harsh complaints there. It's worth mentioning that after installing the 22GXP, there is an obvious increase in speed not only with the hard drive, but also with overall system performance.
SCSI owners will want to stay SCSI if CPU utilization is a big issue for you, since SCSI hard drives have a lot less of a CPU load requirement, however SCSI is a lot more expensive for a drive the same size. Figure about $1000 for a 22GB SCSI drive that is any good.
