SATA vs ATA150 vs ATA133 vs ATA100 vs ATA66.... phooey! The real limiter is the data transfer rate at the disk head. Generally Speaking (IIRC), 7200 RPM drives move data to and from the platters at around ATA33 speed. So ATA66 is about as fast as your hardware will exploit with two drives on the cable. ATA100 reduces bus contention for "both rives ready simultaneously" about as low as it will go; ergo ATA5000 is not faster than ATA100 in measurable effect. Buy more RAM... that'll speed you up more than going ATA5000 instead of ATA100.

They're listed as SATA. SATA1, which is currently available, is the equivalent to ATA150. SATA2, due out in a year(?), is supposed to be equal to ATA300, 2x the speed of SATA1. > I'm going to hang on to my home-brew linux RH8 departmental server > with 3x 200GB IDE Drives on PII 300. > > my 2 cents Nod. SATA isn't for everybody, and if you've got a working system, there isn't much need to go and disturb it with new hardware. For new system purchases though, it's something to consider, especially when using them with 3ware cards (Linux supported) for high density hardware raid. -- Jesse Keating RHCE MCSE http://geek.j2solutions.net Mondo DevTeam (http://www.microwerks.net/~hugo/) Was I helpful?
