Slow read and write speeds on SSD

Hey,

So I finally got around to picking up a 64gb SanDisk SSD to use as a boot drive for Windows 8, but I am somewhat underwhelmed by the performance "increase".. 

I ran an AS SSD Benchmark as you can see here - http://i.imgur.com/8AiiWL4.png 

I did install in IDE mode unfortunately, and while changing the BIOS to AHCI doesn't cause a BSOD, it does give an error message upon boot and doesn't help with performance.. I have had a look around and did find a guide to editing the registry to successfully change to AHCI mode, however, I was only able to find anything relating to Intel chipsets..

I also ran the SanDisk SSD Toolkit, which says that there is no firmware information for the device..

Is there something I am missing/not doing correctly??

Full specs if it helps: 

AMD FX 8320 @3.90GHz

CoolerMaster Hyper 212 Evo

EVGA GTX 680 SC 2gb

7gb Kingston DDR3 RAM

Gigabyte GA-78LMT-UBS3

CoolerMaster GX Lite 700W PSU

SanDisk 64gb SSD

Western Digital Black 500gb

Seagate Barracuda 250gb

Thanks for taking the time to read, and in anticipation of any responses..

you should reinstall windows on AHCI

I was hoping to avoid this if at all possible, you think that is the only way??

i believe it's the easiest way, not sure if it's the only way. get your windows install on to a usb and installation on to an SDD will not take long , if that's what you have issues with.

man i just made your day.

Thanks for the links man, appreciate it.. I did come across something similar to the first one (OCZ), however, my registry doesn't have "msahci" under HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\.. 

Again, I'm not sure if there's something I am missing or what.. If I can figure out what I need to change in the registry, then that second link would be a godsend..

Thanks for your help..

That may help methinks? 

Being a small model of a low tech drive running off a 3GBps interface those numbers aren't looking too bad. Getting into AHCI mode is still recommendable, but it won't change a whole lot. It's still a worthy upgrade from a mechanical drive.

Enabling AHCI, will fix your problem.   >> http://www.ithinkdiff.com/how-to-enable-ahci-in-windows-8-after-installation/

Unless something has changed over the last couple years you will never get quite as good speeds as intels SATA3 chipset. AMD's chipset is lacking compared to intels. But yes get it switched to AHCI and you will be much better off.
