I ordered and installed the 9550.
The 9550 was the only card available at the time that worked with the motherboard, that didn't cost $5K and was SATA. (Yes other boards were available, but the PCI spec on the Motherboard forced the choice... as it was currently not supporting certain types of cards)
The Card's firmware needs to be updated seriously.
The kernel Scott *WAS* running was Sarge's, Right? (2.6.8)
There have been some firmware updates that have addressed many issues since I bought the card.
As far as using Adaptec cards... FEH.
I have *MORE PROBLEMS*, in both slowness and data consistency with SCSI and SATA via Adaptec RAID cards than the 3Ware Cards.
Adaptec Firmware updates for "Adaptec brand" cards only, if you have an "OEM" card you have to get them from your OEM which drops your version 6 months after you buy the damn thing.
I've only had *ANY REALLY GOOD LUCK* lately (4-5 years) with MegaRAID series of stuff... and I am still skeptical as they used to Sucksoplenty back when Dual Athlon MP processors were the rage... what 7-8 years ago?
The only server class stuff I REALLY still trust at all is the IBM ServeRAID stuff. Bucksoplenty for them.
