Does my laptop support SATA-III?

post #1 of 9
Thread Starter 
Alienware M11X-R2, Core i7 model with a Seagate 320 GB hard drive. Does it support SATA-III or is there any free utility I can run that will tell me? I talked to a Dell representative over their free chat utility and they couldn't tell me anything.

I want to put an SSD in it so knowing my interface will help me decide whether to get a current C300 or wait for the newer SSD controllers in a month or two which may not be worth the extra money if I'm limited to SATA-II data rates.

Sorry, but I was asking about SATA, not USB.

Pretty sure it doesn't, since intel boards didn't support sata II natively until the sandy bridge chipset that was released this year. It may have a 3rd party marvell controller on it, but usually laptops stick with a generic intel design. A single SSD isn't enough to saturate a Sata II interface anyways.

edit: Just checked your mobo is a Mobile Intel® GS45 Chipset, which has a ich9 southbridge, so no Sata III I'm afraid.

Thanks for the info, Dman.

tbh even if u had a sata3 drive on sata 2 port it wouldnt saturate the bandwidth, so you wont notice a difference unless you raid like 50000000 drives

I think the Crucial C300 256GB does saturate SATA-II. If so, the newer controllers will be even faster but I'd rather get the slower C300 since I don't want to pay for extra speed I can't use anyway.

I do not think any SATA III laptops exist.

Or not.
Every c300 model has a rated 355 MB/sec sequential read.

IIRC SATA 3 Gbps tops out around ~290 MB/sec due to error checking and bus overhead.
