    Okay so I've been reading up on so many people having problems with their SSD with yosemite and would like a little clarification.

    I'm planning on buying and installing a Crucial m550 ssd with my 2012 Macbook Pro with a fresh install of Yosemite. I'll also be getting the most current TRIM Enabler from Cindori and was wondering if there was anything else I need to do besides back up my current hard drive?

    The reason why I'm confused is because I first was planning on getting the Samsung 840 evo which I read so many people having problems with but was wondering if I would come across any problems with the m550 like those who have the 840 evo...

    From what I read, slow read and write speeds were somewhat affected with people who have the evo but can be fixed with an update that people were having a hard time doing? Are all ssd drives like this?

    Sorry for the long post. I just want to make sure I buy the something that won't give me any problems while installing.

    The M550 is fairly new; it is always possible that there are issues that haven't been discovered yet. But given the known issues with the Evo I would say the Crucial is a much safer bet at this point.

    Not entirely out of topic. I just installed a Crucial MX100 512 GB SSD into my 2012 MBP. It worked like a charm!

    I also have the MX100 512GB and it's working flawlessly with Yosemite on my 2010 17" MBP. I did install the drive prior to upgrading to Yosemite, however, although I didn't experience a single issue with the upgrade to Yosemite or since.

    Get the MX100, have a good price. Make a clean install. NO TRIM, if the SSD does not come with it activated by factory, Do not TRIM it, I all ready have a lot of problems in the long run with trim enable on some drive.

    The MX-100, come with a build in Garbage recollection System, that works ok and is safe and automatic.

    Just disable the sleep properties in energy saver in System Preference and you are set to go. No problems, for me and I am a power user.

    There is a alternative, but i need to check reviews, is the Transcend JetDrive and the small reviews are very promising and come with a software that monitor the drive, activate the trim, and a USB caddy to make the transfer to the new SSD. make sure you run the firmware update from their website, and is easy to follow.

    If what you want to have full averythinh get the OWC. prices are almost the same and it comes with trim enable (warranty is fantastic also the CS they give a lot of tips and notes). Since i did not have the extra 150 USB for the OWC, i get the MX100 512 for 200us and i am very happy with the performance. No regrets

    Macbook Pro + Crucial M550/MX100

    I have both Crucial M550 1TB installed on MacBookPro Early 2011 & have currently (just changed to use 1TB SSD on another project) Crucial MX256GB - the M550 Writes nearly off the scale on BlackMagic Speed Tester & Reads off the scale. With the MX100 it is slower on the Read but off the scale on the write. However - nothing to do with the MacBookPro Early 2011 17 i7 2.2Ghz 16GB issues, of which, there are plenty that Apple/Mac have to address... but be aware of issues with the New Belkin Thunderbolt 2 Hub & using Inateck Enclosures that are Not Powered Separately - they will either erase header data or will give an almost Non Speed on BlackMagic Speed Tester - this could be a conflict with Belkin - Crucial - Inateck ... with powered Inateck Enclosures I'm getting USB 3 (via the Belkin Hub) almost that of Thunderbolt (SSDs of course). Hope this helps. As to the issues with Apple/Mac & Early 2011 MBPs that's another matter.

    Do you happen to have experience with the m550? I know you recommend me getting the mx100 but from a little research, the m550 beats the mx100 in every aspect and is only $10 more on amazon.

    just installed the m550 and I'm stuck at the steps where I Erase and Format the SSD. Its stuck at "Partitioning. Estimated time: 12 Minutes" and the minutes part continues to go up while the blue bar has been on the middle for awhile and doesn't look like its moving.

    any ideas?
