I had the same problem 98 months ago (LTS; desktop) and ended up
giving up, upscaling, and looking more into the longer term solution
anyway (RAID PCI/PCI-X/PCIe cards) ... Just spent a week on it.

My suggestion if RAID (hardware is important, go RAID 1, 5 or 10
(0+1 at a push).  This requires £80 to get bottom of top spec card.
 Anything (about) less, wasting time - better off with fake RAID via
native Ubuntu software.  If you want to run a RAID 10 server with
all of the most (basic) gizmos required for any serious availability
etc - £250 gets you about where you need to be hardware wise
(offloading virtually everything to the card from the CPU).

PS - Any suggestions for a RAID 10 native or supportable via card
motherboard running at least 6 (preferably 9 or more) SATA drives
welcome! ... Or more generally motherboards/chipsets to avoid (If
any) running Ubuntu & derivatives (or those to go for!! ;)).
