Frequently Asked Questions

  • Is this compatible with my Mac Book Pro Mid 2009 laptop?

    It's compatible with any SATA equipped Mac, which means you are good to go. Just make sure you have TRIM enabled after installing it on OS X. The utility I use is called Trim Enabler. With regards to the previous poster's comment, I've taken my Mac apart many times now and I've never had a problem. iFixIt has great tutorials for every Mac that covers how to disassemble your laptop safely. I recommend printing out their guide's and then putting the screws on top of the guide's pictures, so you know where to put them back.

  • Why the 830 series cost more than the 840 pro, this one seems faster. what am i not getting?

    830 supply is running dry, so you are probably only seeing the 830's being sold on the marketplace by stores with less competitive pricing than amazon.

  • Will this fit in a Mid 2012 Mac Book Pro? It holds a 2.5in and up to 9mm.... Thanks in advance!

    Yes, using it now. Macs do support TRIM. It can be turned on using third party widgets and tools. Apple turns on TRIM for APPLE SSD's but others can also be turned on.
