i`m running SATA RAID0 array, and so far (3 weeks now) all is good. no data
corruption, loss, pauses or anything negative. just 71mb/s rather than the
30mb/s i was running before on an ATA133 maxtor :D

Madman. Why would anyone pay twice as much for something that's half as
reliable?

Even with regular (presuming you're meaning parallel) IDE, you'd have to be
stupid to run two disks in a RAID set on the same channel. You can only have
one outstanding request, so you would be effectively halving the performance
of your array.

Note this is *not* the case with SCSI, where you can have multiple
outstanding requests per channel (and possibly per drive, I can't remember
exactly).

The scsi controller handles all IO on the scsi bus and can multitask
IO. I am
running:
adaptec 2940UW controller on a K6-3 400
9GB UW IBM hard drive
scsi cdrom and zip drive

Consider 1.6GB on to the harddrive from the cd through decompression
in less than four minutes. The only drawback to scsi is the cost.

the same reason people buy ferrari's. all about speed and image.

also, i have no valuable data on my pc that i dont mind loosing. ok, an
inconvience if a drive fails and i lose all data, have to download drivers,
software etc etc all again. then again, redownloading everything i get rid
of the many files i downloaded but never used, and get the latest versions!
