Hi Chris,
I think a RAID 5 setup should do the trick for you.
It's faster than RAID 0+1 (at least for writing) and
will get you more disk space (66 % on 3 disks vs 50 % for RAID 0+1)
BTW RAID 0+1 (=mirrored sets of striped disks) is quite hard to do with
only 3 disks , 4 would be minimal.
I have no experience with linux raid, so I don't know if
overhead will cost you performance.
As this is a multia , you possibly have only 1 scsi interface , so for
performance,
this might well be the bottleneck with a raid setup.

Here's one you probably don't see much:
I have a UDB with _a_lot_ of disk space. Something like 30GB.
I want to put about 10GB of it as RAID, ~3GB on 3 different disks.
I'm not really sure whether I want to do 0+1 or 5 though. I'm
concerned about the access speed for RAID 5, but want to minimize
space loss. I'm not familiar with RAID and am therefore soliciting
opinions. Speed is secondary to security, but not unimportant, and
I don't want to lose too mcuch disk space. What are people's
opinions for maximizing: space, security, with acceptable speed?
Thanks,
Chris
