Hi Tobi,

I'm using LSI exclusively, never had an issue with them. Their 6G SAS
HBAs are very affordable and remarkably solid. As for the ARECA vs LSI
debate, I'd contest that there's going to be any appreciable performance
difference. *IF* you're running in JBOD, the card should essentially be
a simple pipe for SCSI commands to the SAS bus with as little overhead
possible. I know for a fact that saturating a 6G SAS link isn't a
problem with LSI cards, so I'm somewhat at a loss as to where the
performance difference is supposed to lie.

Cheers,
