The SAS card I had was an LSI SAS1068 card, with 2 SAS (no SATA), Dell
brand. It worked flawlessly with Linux right up to the day the card
died out of the blue.
With a sample size of 1, I don't have the statistics to justify judging
the card or the controller, but I certainly will be sceptical about
using such a card again.
