What I have now, and don't like very much, is an HP SCSI SX-W hard drive array. I have used it with PC's in the past, but it weights ~80 pounds and sounds like a NASCAR race when it is operating. I wanted to replace it with a smaller, sleeker unit. It uses HD-68 pin interface, and I have a cable that adapts it to DB-25, but I think the disks are somewhat unhappy with the communication rate to my Mac (I was planning on hooking it up to an LCIII as networked-storage for all my other mac stuff). I asked about the number of drives because that monster is a 7-disk array, but I have never had more than 6 disks installed. (4x4.5Gb and 2x18Gb). If the bus could handle seven, I'll put them in my case, if not, then I get to build a smaller, more eye-pleasing case.
