Extremely slow SSD speeds?

Hi guys, first post on this forum. There are probably a lot of questions like this but I couldn't find any threads anywhere with a similar problem, and would appreciate if anyone could help me out.

I recently bought a Kingston HyperX 3K 120GB and installed it into my desktop. I installed it (as a storage drive, not as a boot drive) and the motherboard detected it just fine, and I was able to format the drive from within windows.

Weirdly, games (booting game and loading maps) didn't seem to be any faster than my old HDD, so I decided to run a few tests. Copying and pasting a 15GB .dat file from one folder to another inside the SSD started out at around 120MB/s and slowly started going down to 60MB/s. Running CrystalDiskMark gave me read and writes at around 120MB/s as well.

The motherboard is EVGA nForce 750i, so the SATA ports are SATA II, not SATA III, but shouldn't SSD speeds still be at least double what I'm seeing? Is it something to do with how I've set it up (I picked GTP, not MBR when formatting it) or do I need to do something more to get it working properly?

If it makes any difference, I initialized using GPT instead of MBR. Windows also brings up the AutoPlay prompt for the SSD volume every time I boot my computer up.

Appreciate any replies, thanks!
 
Its not due to SATA2 or SATA3. And SSDs main advantange aint the raw speed. its the seektime. A HD is usually around 14000us. And an SSD around 65us.

Something seems to be wrong tho. Autoplay shouldnt open. GPT vs MBR doesnt matter. But its obvious it aint your boot drive. The copy to itself speed doesnt look that bad either. Its also a sandforce controller...

It might simply be your very old chipset/motherboard thats the limit. I never heard any good stories about nForce chipsets.
 
Run a simple benchmark like crystaldiskmark on the drive and report back the results.

Chances are your copy test is on the same disk, it is 120MB/s read and 120MB/s write, which probably sounds more reasonable. But anyway do the test and then we can comment on if its performing as it should or not and possible remedies.
