Popping open the Samsung 845DC PRO reveals a standard looking SSD. Unlike the 850 PRO and 840 EVO, there is a full-sized PCB that fills out the aluminum case. As we mentioned earlier, the 845DC PRO utilizes existing components, including the flash controller.
The MDX controller, used in the 840 PRO, is a triple-core ARM Cortex R4 clocked at 300MHz. This is an 8-channel design that is clocked slightly lower than the 400MHz MEX controller used in the 840 EVO.
Next up we have the star of the show, the 24-layer 3D V-NAND. We won’t go into a lot of details about 3D V-NAND, as we have covered it in our 850 PRO Review, but we will say that the benefits of 3D V-NAND really show up on enterprise products. Not only does it deliver great write speeds, it is able to hit the industry standard of 10 DWPD without any tricks.
Our 800GB sample consists of 8 NAND packages, each consisting of 128GiB, giving us a grand total of 1024GiB, which is very typical for this class of product. On the 400GB model, there are half as many packages.
Our sample also came equipped with 1GB of LPDDR2 DRAM across two packages.
Finally, we have a row of capacitors that provides power-loss protection of all data that is in flight when power loss occurs.
