    OCZ Vertex 2 120gb installed in a mid-2010 Macbook pro. The speed tests are surprising now. it's been in use since 2011. Is there something wrong with this ssd? Yosemite is laggy and I'm wondering if the SSD has anything to do with it.

    Would replacing it with an 840 evo be a good idea at this point?

    Have you tried running trim enabler??

    This will refresh your ssd and should get yours speeds up if you haven't used it already.

    3 years with no trim will do this to your SSD.

    You can download here, the basic version is free.

    You're using Yosemite? Be careful with trim since it may destroy Yosemite (in Yosemite, you aren't able to modify kernel extension, which Trim Enabler does. You can find more information, and how to fix it, here.

    It's a Sandforce controller drive. OP is best doing a secure erase via the toolbox then restoring from backup to get back the original performance.

    Samsung and Marvell controller based SSDs (e.g. Crucial) offer better long term reliability and performance for OS X.

    An 840 Evo would be a good option.

    See if you can get TRIM enabled even if only temporarily. Then boot to single user mode and from the command prompt enter "fsck -fy" (without the quotes) and that will TRIM all unused blocks on the drive and hopefully restore performance. Then type reboot to restart.

    Secure Erase

    I've done a secure erase and a restore from clonezilla but the issue persists. Really don't know what's wrong at this point.

    That should have fixed it. SSD might be dying, or since you are using 10.10, could be a driver problem of the beta.

    Did you enable TRIM?

    The SSD could be the problem... I thought all the OCZ Vertex 2 had been RMA'd already. :)

    One other problem could be the SATA cable.

    If you had a newer MacBook Pro with USB3, I'd suggest you take the SSD out of the Mac and put it in a USB enclosure and see if it's any faster, in which case I'd think it was a SATA cable or some other problem internal to the Mac. However, I'm not sure that method would be useful with USB2, as the SSD would probably still be slow due to USB2, even if the SSD was good.

    I'm running TRIM on my Crucial M500, but if you have just done a secure erase, then I don't think TRIM will make much difference in the short term. The main benefit of TRIM is in long term performance and some people will tell you not to use TRIM with those Sandforce controllers anyway.
