RAID-1+0 generally refers to striping a bunch of mirrors,
where RAID-0+1 means mirring two stripes.
RAID-1+0 is generally more fault tolerant (you can lose
multiple drives, as long as you don't lose both drives
from one mirror, as opposed to RAID-0+1, where you can
lose multiple drives **only** if they are on the same
mirror)
I don't know, however, whether Linux's raid tools support
both options or not (true RAID-1+0 is a lot less common
in industry than RAID-0+1, since it is a little more
difficult to implement correctly).
Hope that's a little help...
(I don't have a raidtab to send you, 'cause I've never
built a Linux box big enough to need either option -
I've only ever used two drives at a time so far.)
