Mark, thanks very much for the reply.  Sounds like the 88SX7042 is a good solution.  A couple more questions:

1) There seems to be talk on the mailing list about a bug where on highpoint controllers using this chip the controller corrupts some data on non-raid disk members.  I assume this is caused by the specific firmware on highpoint controllers using this chip, and that if I use a non highpoint version of the 88SX7042 that I won't see this problem.

..

The firmware on the Highpoint RAID cards unconditionally overwrites
sectors on any attached drives, before booting any O/S.

Never plug a drive that already has data on it into any Highpoint RAID card.
But for new drives, just partition around the firmware areas and you'll be fine.
There are notes (and a WARNING) in the driver source code regarding those.
Avoid sectors 1..63 (cannot boot from this controller as a result),
and avoid the final (full!) GB of each drive.

2) You said this is the best marvell solution for Linux at this time.  Is there a better SATA controller that I should be thinking about other than the 88SX7042?  I know the ICH9R's had good performance, but no FIS switching for PMP's.

..

Dunno.  I think everyone in the biz is going to AHCI style controllers now.

Cheers
