What kind of disk setup does RAID require.  Do all disks have to be
SCSI.  The same size?  Can you have Mixed EIDE/SCSI?  Just trying to work
this out before purchasing so I can play with RAID 0.

If you mean software RAID 0 using md, according to the docs you cannot mix
(E)IDE & SCSI disks. You have to use one type for every RAID 0 device
instead ((E)IDE or SCSI). Disks do not have to be the same size.
I tried it with my EIDE disks (540MB and 105MB) and it worked OK.

A commercial RAID solution is going to have its own requirements.
Usually, all SCSI disks and a specialized RAID controller card. There
are some IDE RAID cards out there, but none are supported by Linux.

However, if you're talking about the "md" driver, there is a mini-HOWTO
on the subject that I suggest you read. Your answers are there.
