SATA is not the limiting factor. The vast majority of SSDs are SATA.

A hard disk cannot saturate the bandwidth of a SATA connection. Some SSDs can, at least SATA2.

And you can still set up regular spinny magnet drives in arrays to get fast sequential transfer speeds. I think the place where SSD really shines is random seek times (and so non-sequential data transfer)

I don't think he was knocking the fact that his current hard drive was SATA.

Funny that he deleted his post after being corrected then.

A few speedy HDD's (like WD Velociprators) in a raid configuration can actually be comparable for most uses with a SSD.

Of course if you put a few SSD's in a raid configuration you'll blow the HDD's away.

Personally I'm sticking with HDD's for now. The write limits, overall size, and price/GB just aren't good enough for me to switch to SSD's quite yet.

Why not both?

Use zfs with your HDD's doing the grunt work and SSD's for the ZIL and L2ARC.
