You sure that Marvell thing was hardware RAID?  Currently, Marvell  
SATA controllers are not supported by stock Linux kernel.  There's a  
driver source somewhere on Abit's FTP server that should work (more or  
less) stable on 2.6 kernels.  I'm talking here Marvell SATA  
controllers (including fake-RAID ones), not SATA based hardware RAID  
controllers (if Marvell makes any of those at all).

Adaptec and 3ware solutins seem to work nicely.  With Adaptec, I'd be  
carefull to get aacraid based card, not I2O.  In my very limited  
experience, 3ware cards were not as flexible as Adaptec's aacraid  
based cards.  The 3ware you configure once and that's it.  With  
Adaptec, you can migrate data from individual drives into RAID arrays,  
expand arrays (even RAID-5), change RAID levels (migrate volume from  
for example RAID-1 to RAID-5) and so on.  All while the host is up and  
running.  Well, at least with those I had in my hands (like for  
example the SCSI based 2200S).
