Product Showcase

The SSD can be opened up easily enough after which the PCB and its components become visible. The controller has a thermal pad applied to it and as such the shell casing helps cooling as well. To the right you see the SATA 3 connector. This 6Gbps storage unit makes use of A15nm Toggle NAND from Toshiba.

For the 256 GB version which you are looking at, 8 NAND flash memory ICs are needed on the PCB, they make up the volume capacity. The NAND FLASH partitions are arranged directly towards the Silicon Motion SMI-2246 controller. 
 

In the photo above we zoom in a little at the DDR3 memory cache chip from Hynix, depending on volume size (128/256/512GB) DRAM cache sizes are 128 MB, 256 MB, and 512 MB, respectively.
 

As stated several times by now, the Toggle NAND used is 15nm in architecture, a batch of Toshiba NAND memory. For this 256 GB model you will spot 8 ICs on this side of the PCB.
 

And yes, if it was the 512 GB model, the backside would get 8 NAND ICS here on the SMT traces.
