Hello there,
I recently bought a Kingston SSDNow 64Gb SSV200S37A64G and reinstalled Windows 7 on it (clean install with only that disk installed). It's working quite well, and I can see the improvement over my old HDD, however, the benchmarks I've done got me worried.
At first, I didn't do any benchmarks, but my Windows Score for the disk was 6.9, so I wasn't worried. However, after adding 4Gb of RAM to my system (there was a struggle because of the overclock and the other RAM module, but now it's working), I did the test again, and it showed me 5.9 (same score for my old HDD) for the SSD. I found it odd and began to benchmark, which revealed some worrying results.
Before I show the results, I must say that the SSD is connected to a M4N68T-M LE mobo, which doesn't have SATAIII (it's SATAII) and has Geforce 7025/nForce 630a as chipset. The drives are updated (though they go way back to 2009/2010).
So, these are the benchmarks results.

I don't know about the read values, but the write values are awful. Sequential writing goes way down to 26MB/s, this is 1/4 of a regular HDD. I tried this in practice and it's real, copying a file inside that SSD is a slow process (but copying from a different drive to it it's kind of fast.).
I know there are other people with this issue here, and I followed some posts, but couldn't work it out. And none of them have such bad results.
Some things I've tried:
I checked that TRIM command is on;
In the BIOS, ACPI and other option are enabled;
I tried to search drivers with SlimDrivers;
I tweaked Windows7 (Defrag was off already, hibernation is off, searchindex is off, power options are set to performance and no sleep, reduced paging file, no more prefecth, write caching is enabled, MBR is in this disk etc.)
Lastly, here are some screenshots of how Windows is seeing the drive and controllers:

I hope I can figure it out with your help, guys. Thanks a lot.
Edit: Currently 40GB free (of 60GB).
