Wanted to spread the word on a few of the forums I frequent. The main post was over on Overclock.net-samsung-magician-4-6-released

Samsung Magician 4.6 was released and supposedly fixes the read degradation issue on 840 EVOs.
You can download the latest Magician from Samsung here: http://www.samsung.com/global/business/ ... 3-11000279

Download issues on samsung's side of things seems to have gone away.

Some of the history if you are not familiar with the 840 EVO issue:



The process should be straight forward.
What you want to do is Download and Install the latest Samsung Magician 4.6.
Launch Magician and Firmware Update should have a Warning sign next to it. Run the update. It takes a couple minutes, reboots, and your 840 drivers should be re-installed.


After rebooting, launch Magician again, and go to the Performance Optimization section > Advanced tab. This is the new performance fix. Depending on the capacity of your drive this could take 20 minutes to over an hour. If your 840 EVO is a game drive I wouldn't worry about it interfering with general computer use. My 90% full 840EVO took exactly an hour.. It used about 20-30% CPU across 4 cores, but I didn't notice it running.


The new firmware runs this in the background to keep reads up to speed, but you can run it whenever you feel like. I would run something like HD Tune or HD Tach to check your read speeds since Magician does not seem to pick up the slowdown. According to PCPer, it uses something like 1 of your drive's NAND writes (like an insignificant 0.1% of the drive's life), so its not going to hurt the drive unless you do something stupid like run it every day for a year, and there is really no need to. If the firmware doesn't fix it, you might have to run this 6 months from now.
