A while back I bought a crucial C300 specifically to take advantage of the sata 6Gb/s capability on my motherboard but my read speeds over sata 3 were no where near what they were supposed to be (around 190 MB/s when the drive is rated for 355 MB/s). I posted a few threads in various forums including one on here but I never had any luck getting my speeds right. When I use the drive through sata 2, the speeds are right around what they are supposed to be so I know the drive isn't bad. I got so sick of messing with it, I stopped using it and starting using my F3s in raid0 for my boot drive. It's been a few months and I think it's about time I start using what I payed for.
Things I have tried:
I have done a fresh install of Windows in IDE and AHCI modes.
I have been told that there was a difference between Sata 2 cables and Sata 3 cables so I tried them both.
Enabled and disabled write cache on the drive.
My board has two ports for sata 3, I tried them both with various cables.
I have updated the firmware on the drive to the latest version.
I ran the benchmark with and without the sata 3 drivers installed.
I have tried everything that has been thrown at me and I never got anywhere. The only thing that made a difference was the write cache but it only lowered my speeds when it was disabled (to around 140 MB/s). I personally think it is something in the BIOS that is causing this issue. I read that some people had this problem with a different motherboard and the I/O level up setting in their bios was the problem but I can't find anything like that in my BIOS.
If anyone has any ideas at all, I would appreciate the help very much!
