OS X only supports Trim for their Apple’s own approved drives. Trim is a feature, build into OS’, that makes better use of SSDs. Yosemite and TRIMīefore we go any further, I need to make mention of an “issue” with Yosemite. Taking all into account, it’s definitely worth it if you’re worried about following this process yourself. They will fit a 480GB drive for you, including the following cloning process, for £220. If you’re happy to avoid Samsung entirely then you can plump for a Crucial 480GB model, which costs £149. If you’re wanting to save money the previous generation 840 will cost about £166 for the same capacity. I did think of saving money but simply doubling my storage to 240GB, but didn’t want to have problems another year or so down the line and have to upgrade again. The Evo is the standard version – a Pro version is also available. Yes, it costs a little more but it’s worth it. The 850 is a new model, much quicker than previous models and with a much improved life-span. Which Drive to Choose The recommended Samsung 850 EVO SSDĪfter much looking I decided on the 500GB Samsung 850 Evo, which costs about £200 at Amazon ( see my review here, including a speed comparison with the existing SSD).

So, the guides from iFixit for their general drive replacement will work just as well. However, looking at the underside of the box I found a model number which, when Googled, showed it to be a 120GB Samsung SSD. At first I thought this was some kind of filler, with the actual SSD being a slot-in model hidden away somewhere. Where the drive should be was, instead, a plastic box. To do this, you just need a small Philips screwdriver.

Not 100% sure, therefore, of how to swap it I took the bottom of the Macbook to take a look. Removing the underside from the Macbook Pro Sadly, for me, it wasn’t that easy as I couldn’t find something specifically for my model that already has an SSD equipped. If you have a mechanical drive then it’s relatively easy to find the answer. With lots of “teardowns” available for the Macbook, I thought it wouldn’t be too hard to work out how the drive can be replaced. Thankfully, since, SSD prices have dropped, so it’s time for a replacement. However, although storage of media is still not something I do on it, I do make extensive use of iMovie. As I wasn’t storing music, videos or photos on it I felt that 120GB of storage would be plenty, and the SSD would add extra resilience. It wasn’t a standard build as I opted for a 120GB SSD, instead of the usual mechanical drive. It’s still going just as strong today, now with the latest version of OS X (although battery lift is not what it was). It was back in August 2012 that I bought myself a Macbook Pro.
