Have you by chance enabled AHCI in the bios? If not it is too late and the only way to do that now is with the registry hack or to reload Windows. In case you don't know AHCI needs to be enabled in the bios for windows to use the trim feature with the SSD and for the speed to be optimized. If it were possible to reload Windows then you could put Windows on the SSD and have AHCI enabled , there would be a noticeable performance increase with your computer.
Yes when i plugged the SSD up i went into BIOS and set my marvel ports to AHCI (my SSD is plugged into my marvel ports)
Download & run ATTO benchmark software. If your Read/Write speeds are above 300 MB/s then your drive is ok.
Thank you for the help. After running the ATTO Disk Benchmark it started slow but ended up a little bit over 350 MB / Sec read speed. Not quite the 500 MB / Sec that was advertised but still fast enough for me.
