Sata 6Gb SSD on Sata 3Gbs platform

Hello,

I'm currently interested in getting a Sata 6Gbs SSD but don't want to get a new motherboard just yet because it's a pain in the butt to uninstall/install. If I use a Sata 6Gbs SSD on the old Sata connection, will the SSD run at its max potential for the Sata 3Gbs bandwidth?

thanks,
Andy

Assuming the SSD's throughput doesn't exceed the bandwidth provided by SATA II (which is *theoretically* 375MB/s, so you should be good), it should work just fine using the older interface.

Theoretically its 300 MB/s. Really its about 280.

I would recommend getting a SATA III controller if you are going to buy a SATA III drive. Otherwise, you will be bottlenecking the drive by the SATA II connection.

You can get an Asus SATA III controller that also has USB 3.0 on it for $25. Since it will increase the sequential speed by about 80 MB/s to the full 355 MB/s that the C300 has to offer, I'd say its well worth it.

I was considering this but I read a review from a euro post regarding the pros and cons of using a sata expansion drive. The results were only about an 80mb/s gain in read/write speed. Rather then spend about 30-50$ for a minor improvement in transfer rates I'd rather invest in a new mobo. Any recommendations on a good mobo would be great. Currently I have a Asus P6T6 WS Revolution.

I'm failing to see how a SATA 3 drive on a SATA 2 port would do anything at all besides simply bottleneck the SATA 3 SSD's full potential. I put a SATA 3 SSD into my wife's laptop which has SATA 2 ports, and that sucker screams like no other. She's never been happier. I don't doubt that a SATA 3 port would bring out some more color in the SSD's performance, but I fail to see why this wouldn't be a rather suitable and logical idea for now until you do upgrade motherboards.
