user2 Posted February 28, 2013 Share Posted February 28, 2013 Dear Corsair Forum, I have recently purchased the Corsair Force GT 480GB drive because it was promised on the corsair's website that I will get 550MB\s speed, but it is not true. Maximum I can get is 250MB\s which is more than twice as low as promised. Is this a joke? Why do you lie, Corsair? Here I have ADATA SSD results and Corsair SSD results. ADATA didn't lie - I can see 550MB\s speed but Corsair simply lies and real speed is only 250MB\s. My question is why? Both drives are using identical cables and connected to identical SATA3 ports. Where are my 550MB\s? Where??? Thank you. Link to comment Share on other sites More sharing options...
Toasted Posted March 1, 2013 Share Posted March 1, 2013 Corsair isn't lying. Please make sure the Corsair SSD is connect to a Intel SATA III 6.0Gb/s port which would be the brown ports. The Corsair SSD looks like its plugged into a SATA II 3.0Gb/s port while the competitor drive is on the correct port. If i'm correct. I believe you are confused about the SATA II/III thing. SATA II = 3.0Gb/s SATA III = 6.0Gb/s Intel® X79 chipset : 2 x SATA 6Gb/s port(s), brown 4 x SATA 3Gb/s port(s), black Support Raid 0, 1, 5, 10 Marvell® PCIe 9128 controller : 2 x SATA 6Gb/s port(s), gray ASMedia® ASM1061 controller : 1 x Power eSATA 6Gb/s port(s), green 1 x eSATA 6Gb/s port(s), red Source: ASUS Link to comment Share on other sites More sharing options...
Administrators Technobeard Posted March 1, 2013 Administrators Share Posted March 1, 2013 I would agree with Toasted. The drive simply seems to be in a SATA II port that is limiting the bandwidth to and from the drive. Please do as he suggested and plug it into a brown SATA port and then re-test with ATTO.

user2 Posted March 2, 2013 Author Share Posted March 2, 2013 I agree, indeed you have right to believe that it is connected via Sata II port, but it is not. It is connected via SATA III port. The problem was in default settings of Mboard BIOS. Corsair should update their information where they say that there no actions needed and that speed will be at its maximum right away. They should warn people that almost every new motherboard uses a power saving feature. This power saving feature limits the SATA III speed to 3gb\s. Tested and confirmed.

Synthohol Posted March 2, 2013 Share Posted March 2, 2013 Corsair should update their information where they say that there no actions needed and that speed will be at its maximum right away. thats true, there is no action needed in regards to the drive itself, its up to you the owner of the motherboard to have the BIOS prepared for the install. most motherboards you just plug it in and you are good to go, yours on the other hand required other preparation that Corsair is not responsible to tell you about and this was probably covered in your motherboard manual. im sorry, i just dont see why you may think this is a Corsair problem. either way its all good now i take it so enjoy :): Link to comment Share on other sites More sharing options...
