Actually, wouldn't that give you 160GB capacity but you could not
lose two drives unless they both happened to be on the same side of
the mirror. Why not go with a RAID 5 card (NOT a Promise one though).
I am guessing that you'll need the read performance more than the
write performance so RAID 5 should be a viable option. SyncRAID might
be worth a look but right now their Linux support in in the beta
stage. 3Ware cards seem to be very popular amongst the Linux crowd.
