Update: (April 28, 2015) PC Perspective reports that Samsung has released another firmware update EXT0DB6Q, with a downloadable ISO image for Mac users, to try and finally resolve the 840 EVO performance problem after it turned out that the first update didn’t completely work. This new version EXT0DB6Q is more recent than the version installed by the software in this article.

Unfortunately, the next challenge was to figure out how to install it. As a Mac user I naturally waited until the Mac version came out and fortunately it became available for download a few days before the end of October. The bug fix came out in October 2014, first as a Windows application, and with a Mac/Linux version promised by the end of October. Soon after, I read on Anandtech that Samsung acknowledged a serious performance bug with the 840 EVO SSD that would dramatically slow down read performance for data that had not been rewritten in a while. Anything involving disk access now seemed instantaneous. Replacing the original hard drive was quick and easy, and the improvement in performance was obvious and profound. In late 2014 Amazon had a great deal on the Samsung 840 EVO SSD, and I took the opportunity to upgrade my aging MacBook Pro with it.
