Sata 3 (6Gb) connection for SSD desired

Is it possible to install a PCi card with a Sata 3 (6Gb) internal connection for my new SSD to achieve my desired 6Gb speed rather than use the mobo Sata 2 connection?

Re: Sata 3 (6Gb) connection for SSD desired

If the card is going in a PCIe 2 x1 slot (~500 MB/s theoretical bandwidth), then maybe.  With the overhead you might get between 340 and 440 MB/s.  So, a little bit better than 280 MB/s or so actual with SATA II.

While it is possible its not usually stable.

There are lots of incompatible host bus adapter cards.

Western Digital OEM bundled this card a while back to handle drives larger than 2TB.

There are lots of horror stories about

Not working at all.

Re: Sata 3 (6Gb) connection for SSD desired

You don't say what model, but if it's only SATA-2 on-board, likely just an old Legacy-BIOS system.

On those, you can install a PCIe SATA-3/600 addin card, and it will likely work.

HOWEVER, due to non-UEFI BIOS, it will be hard-to-impossible to get the machine to boot from that drive.

Finally, SATA-3/600 isn't even a fast SSD any more.
