What Adobe products do you use under Linux? I did not know
that Adobe offered products outside of Reader and Flash
for Linux.
Besides, where did you read that Adobe products don't
work on RAID systems?
The RAID part will be well hidden under the Logical Volume
Manager even if the first is true.
RAID1 can speed up sequential read speed, as a well
designed RAID implementation can stripe the read requests
across both spindles (and dm-raid does that!).
