Let's look at the regular SSD first. 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 left you see the SATA 3 connector. This 6Gbps storage unit makes use of 15nm TLC NAND from Toshiba, in total it makes use of eight NAND ICs configured as Toggle TLC.

The NAND FLASH partitions are arranged directly towards the Marvell 88SS1074B1 controller. The controller is covered by a thermal pad that connects to the metal shield. We've seen this controller reach 60 degrees C under heavy load, which is normal.

In the photo above you can also see the DDR3 memory cache chip from Nanya, the 512GB SSD gets a 768MB DDR3 DRAM cache. As stated several times by now, the TLC NAND used is 15nm in architecture, a batch of Toshiba TLC NAND memory. The drives start to be more price competitive at roughly 30 cents (EUR/USD) per Gigabyte depending on the region where you buy it.
