Thanks. Just to confirm, non highpoint 88SX7042 based cards don't have this issue right? This seems silly for them to do such a thing, but some people like their management tools...

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.
