Micron® Quality
As a brand of Micron, one of the largest NAND manufacturers in the world, Crucial SSDs are designed and developed in-house with the latest technology. This means four things: hundreds of SSD qualification tests, over a thousand hours of prerelease validation testing, 1.5 billion dollars invested in R&D, and more than 30 years of industry expertise.
Adaptive Thermal Protection
Greater thermal management enables the Crucial / Micron M500 to work with the host computer to dynamically adjust power consumption based on usage demands, which helps address the cooling challenges of ultra-small, thermally constrained systems.
Hardware Data Encryption
The Crucial / Micron M500 SSD offers top-level hardware-based encryption, enabling enhanced data security. Our AES 256-bit hardware encryption engine and TCG Opal 2.0 compliant firmware allow the drive to operate at full speed without the performance loss that's typically found in drives that use software-based encryption technology.

Rating: 5/5 Great SSD for OS X El Capitan and Public Betas January 25, 2016 I installed this 120GB Micron SSD drive in my mid-2011 21.5" iMac about 9 months ago (June 2015), using the OWC installation kit to add an internal SSD to an existing HDD to a mid-2011 iMac. SSD installation is time consuming, and probably daunting to some, because it requires removal of screen, DVD, and system board to install and place the power and data cables, but I had no difficulties with it by following the detailed OWC YouTube video of the procedure. (I also upgraded my HDD at the same time using the revised OWC HDD kit containing the updated temperature sensor module for mid-2011 iMacs, again following the updated OWC YouTube video.)

I use the SSD exclusively for testing the latest Public Beta versions of OS X and apps, and I've had no issues at all. Boot-up and shut-down times are extremely fast, when compared to a 1TB 7200rpm HDD in the same computer.

120GB is enough capacity to contain OS X and all the Apple apps now supplied for free, with more than 70GB free for data and other apps you want to try out.

I would recommend this item to a friend!

Rating: 5/5 Excellent Replacement Drive for Macbook Pro January 30, 2015 Replaced my HD in 2007 Macbook Pro with this drive. Installation was easy after reviewing OWC video and new SSD drive took about 30 minutes to complete. I then cloned the old HD over to the new SSD drive and you are done. This SSD greatly improves read write speeds and is silent in operation. I also feel my battery life is extended with the new drive.
