I've got a few Ultra 320 SCSI hard drives (Seagate Cheetahs :-D) but I need something to interface with them... I know with all these servers around here, someone must have at least one they could sell...if not, then does anyone know of a cheap place I can find one? I've tried Ebay, craigslist, pricewatch, newegg, etc. and cannot find one...at a reasonable price anyway. Your help is greatly appreciated. Let me know if you need more details..

If you can get by with software RAID, a conventional SCSI HBA would be much cheaper. These SCSI RAID cards can be tremendously expensive.

So I've heard... so if I find a standard SCSI card (without built-in RAID), then will the software RAID be too much slower? I'm already sacrifcing speed by using the 32-bit bus on my computer, so it can't be much slower than that. I'm looking for faster access (and random access) speed, I know my throughput will be bottlenecked with the method and hardware I'm choosing to run this on, but it's still better than IDE and SATA.

Well, if the 32bit/33MHz PCI (which maxes out at ~130MB/s theoretically, but I've never seen more than ~120MB/s, often even less than that, e.g. 100 or 110MB/s) is the bottleneck anyway, I think you won't lose much by using software RAID. I've had some quite good experience with it, it was at least as fast as these cheap "fake RAID" cards, but I can't say much about it compared to real RAID cards with own CPU and cache. Two of these drives in a stripeset (assuming they're fairly new) should easily reach or exceed 100MB/s. I've had a SW RAID of four 10kRPM SATA drives once and managed to hit 220MB/s which was what the drives could deliver (55~60MB/s each).

I got one I pulled out of a Compaq ProLiant 3u server. Worked last time I was aware. No gaurentee though, and I have no use for it. Name a price.

If you want it, name a price.

ADD: reading up on scsi, this is probably not what you want, if you do want it, name a price.

Hmmm... is this an Ultra 160? If so, I'm kinda looking for something a bit faster, but if it's 320, I'll take it off your hands. (The only reason I mention it is because of the details say Ultra2) Does $10 sound good or is that not enough? Let me know...
