The Drive

The drive uses the M.2 2280 form factor, which makes it 22 mm wide and 80 mm long.


Like most M.2 NVMe SSDs, the Kioxia Exceria connects to the host system over a PCI-Express 3.0 x4 interface.


On the PCB, you'll find the controller, four flash chips, and one DRAM chip.

Chip Component Analysis

Kioxia has licensed the Phison E12C controller and rebranded it. Unlike the E12 and E12S, the E12C is a four-channel design. Like the other E12 models, it has support for TLC and NVMe 1.3c.


The four flash chips are 96-layer 3D TLC NAND made by Kioxia/Toshiba.


A Samsung DDR4-2666 chip provides 1 GB of fast DRAM storage for the controller to store the mapping tables.
