I don't use RAID so I can't say much.  What I can say that for RAID, the HD's
are "supposed" to be exactly the same.  That MIGHT be the problem since these
are not even the same size (one is smaller).  If the RAID array works for the
two that are 36gb, then that would verify that.

Your best bet is RAID 0+1 since that is striping for increased performance,
plus fault tolerant redundancy (RAID 1).  I believe you need 4 drives for
that.

On this computer, I previously had three Seagate 15000 RPM SCSI hard drives
(ST336752LW, ST336752LC, and ST318452LW) which all worked fine independently
(or NOT as RAID 0) with an Adaptec 29160 SCSI controller card. I then later
bought an Elite 1600 Megaraid SCSI controller card so I could to attempt a
RAID 0 SCSI array for performance which was successful for quite some time.
Then it began random intermittent system reboots. I was finally able to
realize this was happening only when the SCSI RAID array was active as it
will never happen in any other configuration. I suspect the Elite 1600
controller is the problem and I do not have another one to replace it with
for the substitution method. I may even choose to replace it with an Adaptec
SCSI RAID controller instead but since they are so expensive, I thought I
might throw it out here first to see what anyone else may have to say.
