As said before the casing of this drive is plastic. The screws are hidden underneath the product label on the rear shell of the drive.
Unlike the Ultra Plus, this uses a full size PCB, but all the controllers and flash NANDs are on the single side. Once you pop it, you get to see that thermal pads are stuck in all the flash NANDs and controllers.
The PCB has Marvell 88SS9187-BLD2 controller, followed by 256MB Hynix H5TQ2G63DFR DDR3 Cache chip and 8x 32GB 19nm based eX2 ABL MLC Toggle NAND. This controller has a dual core 88FR102 V5 CPU which support up to 8x flash NAND chips.
Note that SanDisk uses nCache Technology. nCache is one of SanDisk’s Tiered Caching tech which is designed to improve random write performance. According to their research, the modern operating systems usually access storage devices using small access blocks usually in the size of 4KB. In the newer generation flash memory chips they conflict with block structures >1MB.
To take care of this, SanDisk uses 3 types of caching: Volatile, nCache and Mass Storage. nCache is a sizable Caching which works by improving random write performance by accumulating small writes at high speed.
