    Hi guys,
    I've just installed a new kingston v300 120GB SSD on my MBP 2012.
    The Mac was insane slow already during the OS installation, I tried to install El Capitan, but it took too much time and it kept freezing at 80%.
    So I decided to install Maverick, and it went quite good despite the fact that it was still too much slow.
    I hoped it would have been better after the installation was complete, but instead now it's pretty unworkable. It took ages to do whatever action.
    I have a SATA 3 interface, and 4 GB RAM.
    Thanks!

    Kingston V300 is not a fast SSD, but you shouldn't be seeing what you're describing.
    It's feasible you have a bad SATA cable. You might try taking the SSD out and connecting it externally to see how that works.

    Probably something got damaged in the install? That said, should have gotten an 850 evo. I've got 2 1tb evos in my 2012 MBP and they're super fast and going strong 13 months in.
