[solved] Slow Disk speed SATA help

hello, it just accured to me that my harddrive is really slow. I used black magic design test and it said I only get about 50mbps write and 50 mbps read.
I took this my drive from an old laptop I had ( not too old ) so its not new or anything but it might be failing? or maybe there is a hackintosh tip I missed about harddrives?got any recommendations? thanks
