Crucial MX300 2TB SSD review - Product Showcase

The SSD can be opened up and shows a full size PCB. This 6 Gbps (SATA3) storage unit makes use of Micron TLC 3D NAND. A total of four NAND flash memory ICs can be spotted on each side (thus 8 in total) of the PCB for the entire 2050 GB. The NAND FLASH partitions are assigned directly to the controller.

Notice the HUGE battery of small SMT soldered components next to the memory? These are capacitors. So that would be a single layer ceramic capacitor array, In case of power loss the SSD will have enough momentum to write its data, and you thus preserve drive failures and corrupted data.
  

Here we can see that Marvell 88SS1074. This is a multi-core controller with the ability of a possible 175 MB/s to 200 MB/s per channel throughput, which is a really high value yet becoming the norm for enthusiast class SSDs.  Sitting at its right side is a DRAM cache chip, one out of two in use for this SSD.
  

As stated, the NAND used is the 3D NAND which we're sure is TLC written. This 2 TB SSD is guaranteed at 400 TB written, so it'll likely out-live your PC lifespan. The carry-in warranty ends at 3 years though.
  

 
Here we see the backside of the PCB, again we see four NAND ICs. Less components needed equals a cheaper to produce product. You'll also notice the 2nd DRAM cache chip here, summing up towards to 1024 MB.
