there is an article at wickedpc (http://www.wickedpc.com/faqs/harddrivetweaking/B) that talks about the new IBM 22GB Drive ATA-66. Basically ATA-66 doesn't add that much in speed (like 8%), but it reduces CPU overhead alot. So you shoudl be rocking with 3 or 4 of those 22GB beasts in a RAID5.

I believe it is 66MBps per channel, but keep in mind that Ultra2 SCSI runs 80MBps per device and has been around for a couple of years. Ultra3 is supposed to run around 160MBps. My U2/5-drive RAID0 has a "theoretical" bandwidth of 400MBps compared with a 2-drive (one on each IDE channel) UDMA RAI
