<Based on the info I found there about three months ago it looks as if the <UMDA/66's are about the same as a U2W drive. To get the real advantage yo <have to go with RAID and disk stripping. Also, unless I'm misreading thing <UDMA/66 puts about the same load on the processor as SCSI. Yes, SCSI is <still superior, BUT the difference is so slight that you have to ask if th <added cost is worth it. Yes this is all bogus. As a single drive UDMA faster but two scsi drives are still faster as with UDMA (Still IDE) you can only talk to one spindle at a time. SCSI you can have seven on like and with some of the fancier stuff you have the ability to talk to all of them! This makes a real difference if you have system on one, Swap on another and Data on a third. When you interleave like that with queued IO then the difference is substantial. Also RAID with IDE is really flakey! Allison
