I am considering getting a small ssd for my operating system but i am only running sata 2. I know that a sata 3 will work on sata 2 at a diminished speed and will be faster then any platter HDD out there. If i was to get a drive with 500mb/s read and write would i even be able to tell the diffrence on a sata 2 or 3 connection ? . I know sata 2 is 3gb/s and i know that it will never actualy max out at said speed but surley it is capable for reaching 500mb/s. Or perhaps should i stick with an ssd with half the read write say 250mb/s.
