For those who watched last night's podcast live, I predicted that Samsung would be posting their 840 EVO Firmware and new Magician 4.6 software 'soon'. Turns out that 'soon' was actually this morning, but there's a catch - Samsung decided to limit the daily downloads:
If you went to the Samsung SSD Download Page and got the above error, don't fret, there are a few mirrors out there:
I downloaded from these three sources and at the time of this posting can confirm all three are identical to the Magician 4.6 download available from Samsung.
Once installed, you *should* be able to use Magician to update the firmware on your 840 EVO and (hopefully) see its performance come back to where it should be. There have been some reports of users unable to update, but that appears to be Samsung's servers being hammered and Magician's default / timeout is to report that you are on the latest firmware. Restarting Magician may force it to re-check and get the update.
Linux and Mac users are not yet able to update as the ISO updater has not been released for the new firmware. Those capable can update their Linux or Mac 840 EVOs connected as a secondary drive under Windows with Magician 4.6 installed. Also, if you're running Linux and happen use fstrim during boot, read this post prior to updating.

Along with Al's review of the new EVO line you can get a second opinion from The Tech Report about the performance of the new SSD with a fast cache. The majority of the storage is 19nm TLC NAND but there is an SLC cache sitting between the controller and that long term TLC storage to help with the overall responsiveness of the drive, aka TurboWrite. In the 120 and 250GB models that cache is 3GB while in the larger models you get a 6GB cache. In their real world testing the new EVO drive is incredible at large file copying though Sandforce drives can beat it in small file copy speeds, likely thanks to the compressed write trickery that controller family is so good at. Check out the review here and keep your fingers crossed that MSRP is the acual price these drives sell at.
"Samsung's entry-level 840 EVO SSD combines affordable TLC NAND with a server-style SLC cache. We explain the drive's unique buffering tech and explore how it affects performance."
