Friedman [EMAIL PROTECTED] Mainly I was just curious as to whether the fact that the drive was on a separate contorller would override the fact that it is a slower ATA-33 drive. I do have that many drives requiring that many controllers. The motherboard has 2 ATA-100 controllers and 2 ATA-133/RAID controllers. In addition, there are two add on ATA-100/RAID cards with four controllers each. The machine is being used to do backups over a couple of 100 Mbit networks using multiple NICs.. I have a bunch of 80 GB ATA/100 drives in removable drive carriers. The two adaptec cards are used to keep 2 four drive raid 5 arrays. Weekly and Monthly backups are written to this. The onboard raid is used for the OS, and daily backups. It is configured as a mirrored raid with a small partition for the OS and the rest for the dailies. I have 1 GB of DDR RAM. We used IDE because it is much less expensive than SCSI and much better performance than tape. I ended up with an extra bay in the case and unused spots on the controllers so I just thought it might help to throw an extra drive in dedicated to swap.
