I've been one of the lucky ones as my vertex 2 has lasted more than 1 and a half years. I'm using it with a mid-2010 Macbook Pro with ML and a 1TB drive installed in an optibay. I noticed my performance went down and so I did a disk speedtest. The speed is way lower now. Before, it used to be 200 write and 200-something read. Now it's way lower. Is this a sign of a dying SSD? Should I try reinstalling the OS? Thanks in advance.
