Dual Ata100 hdd RAID setup, or Single SCSI hdd?

[CP]

I'm thinking of buying 2 IBM 75GXP ATA100 hdds for RAID setup. However adding little more money I can get a 10K rpm SCSI-160 drive + SCSI-160 adapter. But which one will perform better? Any idea on the pros and cons of each setup???

Thanks

I just put together a RAID system with a KT7-RAID and 2 IBM GXP75 30gig drives, and it is FAST. 44000 in the Sisoft Sandra disk benchmark, and it loads windows in like 5-10 seconds.
Plus the install and setup was soo easy. I just setup the RAID 0 array in the highpoint bois, and it worked like a single drive. plus it's ide, so everything works with it

Did anyone compare the performance between

Two 7200rpm ATA/100 drive in RAID Vs One 10000rpm SCSI-160 drive

Besides, can I put two SCSI in RAID configuration? Other than that, what else would be the best setup if I have two SCSI drive??

Thanks

I think they've test IDE RAIDs vs. single SCSI.

single 10k scsi (160) is really expensive...just $100+ for the card alone...

If you have RAID setup on the KT7, can you still dual boot between two OS? say ME and 2k? What if the OS or hard drive all of a sudden dies, does that mean all your data on the hard drive is unretrievable (ie could I boot into DOS and backup those files)?

Well, it woudl be hard to boot into dos and pick the data off the hard drive, because the whole idea behind raid 0 is to write some of the data to one drive while writing the rest of the data to the other drive. In other words, if say you have a word document, half of it could be on drive a and half on drive b, so you woun't be able to retrieve that word document. If you want the advantage of striping with some fault tolerance behind it you would have to go with either raid 0+1 (striping with parity), or raid 1 (mirroring). With raid 0+1 you need at least 3 hard drives, raid 1 only needs two, but that offers no performance enhancements.
