Slow write speed Kingston SSDNow V200 256GB

I bought the SSD drive (Kingston SSDNow V200 256GB) for greater performance on my pc. Overall it feels much faster than the regular HDD however when i did some SSD speed checks they`re nowhere near the product specs.

Below are screenshots from CrystalDisc and AS SSD Benchmark

As you can see write speed is really bad.
Is there any way to make it faster?

I`m sitting on Windows 7 64 bit my mainboard is quite old Gigabyte G31M-2SL i have the drive connected via Sata cable (i think its only SATA II) on which the system is installed and i also have another HDD drive connected (i dont know if that changes anything).

Any help would be appreciated.

  1. Yes, your motherboard is old and does not support AHCI mode.

    Your benchmark results are probably the best you're going to get.

    It's possible (but I doubt it) that connecting your SSD to port SATAII0 (see page 24 of your motherboard manual), and changing the On-Chip SATA Mode to Enhanced (page 40) may give you slightly better performance.
