Yup each SAS connector can support 4 SATA drives without anything else.

yes I had a SAS controller once doing raid 0, SATA drives work fine on SAS controllers but SAS drives do not work at all on SATA controllers. I think that card will do the job just fine.

RAID isn't about backups, it's about keeping the system running in the event of a drive failure by providing drive redundancy (which is why RAID 0 is a serious oxymoron).

The two cards I mentioned will also run in JBOD mode (just a bunch of disks) so you can use it as just a multi-drive controller if you wish.

The Supermicro is a decent card for its type though there are some reports that the Marvell controller is slower than LSI's. It is also a SATA II not a SATA III controller.

Do you know any mechanical HDD that is bottle-necked by the transfer rates of the SATA II specs? Me I don't, so this is a moot point here.
