New SSD user needs help


Recommended Posts

Hi, I'm a new to using SSDs, I just bought a Corsair Force GT 120gb SSD and It is currently the only drive in my system. I have it hooked up to Sata 3 and It is running in AHCI under bios.


On the box the advertised speeds are 555mb/s Read and 515mb/s Write

I downloaded CrystalDiskMark to test if the speeds were working and I got this as my results, I was trying to figure out what I can do to fix the speeds on the Drive. The read is a little lower than it should be and the write is just no where near where it should be hitting.

The advertised speeds are taken from a P67. However, you should test with ATTO, as ATTO is much more accurate for sequential tests (it tests the speed across different file sizes) and gives you an accurate indication of how the drive is performing sequentially at least.
