It has three cores that can execute multiple instructions at once, allowing, for example, one to be used for reading data, one for writing data and another for optimization. The MEX controller itself is based upon an ARM Cortex R4 (400MHz) processor. This is a triple-core ARM-based controller that is of course SATA 6Gb/s compatible and can be paired with the latest 1xnm NAND flash memory. That boost alone is responsible for quite a bit of the performance improvements of the EVO series. The controller however has received a clock frequency change from 300 MHz in the MDX to 400 MHz for the MEX. So basically these are small improved respins of the same controller used, and yes it uses the very same 3-core ARM Cortex R4 base product. That means these are small evolutionary changes based on the same architecture. In fact there's an easy way of explaining that name, the MCX controller was used in the 830, the MDX in 840 and 840 Pro and the MEX is now used in the 840 Evo. Storage Capacity: 120, 250, 500, 750, 1000 GBĬoming from the 840 and 840 Pro you'll notice that Samsung now is using the MEX controller.I hope what i have written come helpful for someone and Samsung reads this.

If what I claim is true SAMSUNG SHOULD INFORM THE USER ABOUT DRAINAGE ON LOW RAM SYSTEMS OR SYSTEMS WITH SHARED GPU RAM !!!! I have been working on the PC some hours and I am currently writing this report with no problems so far. I HAVE JUST INSTALLED 8GB RAM ON THE SYSTEM and REACTIVATED THE MAGICIAN. Therefore if there is drainage from both factors you can run very fast out of RAM and get sudden random crashes (any random moment that u need more ram from the pc and it is drained). Bear in mind that when u share ur ram with gpu the system already is drained in Ram by sharing (I have read somewhere that for some clock reasons it also consumes twice as much and uses half! Not an informatics engineer so I cannot explain or understand why). I read that rapid mode uses more Ram where it saves data, programs or part of programs where it executes it when it needs. I have cross checked it and re activate and got a crash within 15mins. I did not find anything installed there so I assumed that the rapid mode would do the same thing. I have read some threads that uninstall the Enhanced mode in control panel in programs and installation would solve the problem. After the 1903 win10 update i measured about 10-12 per day I have a lenovo Laptop on Win10 with 1TB Evo 860 Magician v5.2.1 and 4gb Ram shared with GPU
