Tan, 64 bit 60Mhz Bus Green 64 bit 100Mhz Buss Dell PowerEdge 1600SE I got two spare SCSI HD's so I wanna buy another PERC RAID controller plug it in and move our data files to these, and leave the first for SBS. The newer one might be better, so I would pull the old, put the new one in with original drives and get it running on that. Or is it not that simple? Thank you, Eric Vogel Computer Running Slow?
