I'm afraid I don't know that for certain. I know the card HAS firmware since I've updated it once before. I'll see if those patches solve the problem. If not, maybe I can figure out more about the card to help us along. I can tell you that the card uses this controller chip: https://www.marvell.com/content/dam/marvell/en/public-collateral/storage/ma= rvell-storage-88se94xx-product-brief-2011-04.pdf I'm not accustomed to interpreting hardware information at such a low level myself, but it mentions offering "native 6Gb/s SATA interface support." --=20 You may reply to this email to add a comment.
