You'll want to get a large enough drive so 1/4 to 1/3 of it is kept free once you install all of your stuff. You'll need to follow this: How to enable TRIM on third-party SSDs in OS X. The only thing here I do strongly recommend is you run the latest version of Yosemite (10.10.4 or newer) as it has TRIM services natively. Here's a good write up: Samsung 850 PRO 2TB SSD Vs Samsung 850 EVO 2TB SSD while they are biased to the Pro, our user's experience over two plus years of use suggest the EVO was just fine. In the real world the EVO will serve you just as well at a lower cost. While many claim the Pro's speed and longer warranty is better. Still a fantastic upgrade, but remember to treat the hard drive in the optical bay as slightly more prone to failure than before.To start with you'll need to follow this IFIXIT guide: MacBook Pro 15" Unibody Mid 2010 Hard Drive Replacement to replace your current drive with a SSD.Īs to who's SSD: We have mostly been using Samsung's EVO SSD's We don't use the Pro version. but the one in the optical drive area definitely no longer can protect itself from rapid movement. I put an SSD in place of the old drive, so I can't confirm if it still works in the actual hard drive area of the computer. Now when I pick up my MacBook when the drive is spinning, there is no click. If you ever pick up your laptop quickly and hear a click, that is what is happening.Īfter installing a hard drive where the computer only ever expected an optical drive, that safety feature is lost.
When the sensors detect motion that is violent enough to risk damaging the spinning hard drive (and it doesn't have to be much), the head gets temporarily disengaged from the disk so that the risk of damage decreases. The MacBook has sensors that detect motion. After finishing this guide, it occurred to me to test out a little known feature in MacBooks.
