Product Showcase

Here we can see the PCB a little better and see the controller. The adhesive cooing sticker was nearly glued on there, to prevent any damage we left it as-is. However, as such we could not take a photo of the controller. We do know what's underneath there, as we tested the regular 2.5" MX500, next photo. 

So that would be this controller, the Silicon Motion SM2258 4-channel controller, SM2258 also features advanced SLC Caching algorithms for optimal sustained performance with that NAND.
 

 
You will also spot a Micron DRAM chip, one for this SSD. That would be a 512MB DRAM cache buffer, however, at the backside, there's another one. I assume the 1 and 2 TB models also get 1024 MB cache, the 250 and 500 GB models have a 2x256MB DRAM cache. The performance rating for all volume sizes remains the same though.
  

And sure, the NAND would be Micron 7VA22 NW926, TLC (writing three bits per cell). The ICs are not recognized in any database just yet, so it's the new batch alright, 64-layer V-NAND.
  

 
Here we see the backside of the PCB, again we see four NAND ICs. Small PCB eh? Missing compared to the MX300 and MX200 are all eh ceramic capacitors preventing data-corruption at power loss. However, Crucial's modified its flash program sequencing for its NAND flash, this results (they claim) into the same function. So they should be able to survive a power loss.
