OWC SSD help....Mac to windows drive switch

[Tin88]

I recently built a high end gaming computer and I took my 120GB OWC SSD 6G from my '11 13" Macbook Pro to use as my OS drive. I've ran a speed test, switched the cables out and switched ports but the drive does not go over 200MB on file reads. Any applications I can use to test it? (no longer have the one that was on my MBP that I used all the time; forgot the name). Do i need to install drivers? It automatically installed a driver on its own after i switched ports but still no increase in speed. Please help!!!!
