I'd like to use SCSI RAID on a single processor motherboard. If the board comes with IDE RAID, what will I need to make SCSI work, just a SCSI controller card or a SCSI controller card that also incorporates RAID? I'm thinking of ABIT's KR7A-RAID or similar, but it would be better if there's a socket A/KT266A board with a built-in SCSI RAID controller. Point me towards a link if this is the umpteenth time this question has been asked.
Thanx for the info. I'm putting together a box to run Photoshop (swapping/scratch disk intensive when RAM is depleted) and scan photos in parallel. The scanner's interface is SCSI. I also want a MBO that can handle a lot of RAM--the afformentioned ABIT KR7A-RAID is one or the few fast boards that has 4 184-pin DIMMS. Since I need a SCSI controller for the scanner, I might as well go a little further and get a SCSI board with RAID so that I can feed two disks.
BTW, there are fine Photoshop forums out there, but none that dispense good h/w advice.
"What's the frequency?" you ask. You mean the disk speed...It'll be 10,000 RPM. So a little slower than two 7200 IDE drives.
If you've only got 1 SCSI disk, RAID won't help..
Also, I've never seen any real comparisons on this, but if you're running XP or 2000, and you do happen to install a second SCSI disk, AND you don't feel like spending extra on RAID capable SCSI card, then windows can do it for you. I know there isn't much hit to the CPU (with GHz laying around since the whole RAID 0 function is dead easy to do.
One other thing to note: If you're considering a high-end drive (Quantum Atlas(now maxtor) or Seagate Cheetah) Those drives really get the peak performance when they're slammed by many requests for data simultaneously (as in a server for banks). Other than that, streaming 1 or 2 files through photoshop won't allow those drives to do their thing, and a 7200rpm drive would be just as good. And with the money you saved you could get double the ram and really see a performance improvement.
