The Drive

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


While most other M.2 NVMe SSDs transfer data over the PCI-Express 3.0 x4 interface, the XPG Gammix S70 Blade connects to the host system over a PCI-Express 4.0 x4 interface, which doubles the theoretical bandwidth.


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


You can use the drive without the heatsink or install the optional, included heatsink. It's just a simple strip of metal with sticky tape on one side.

Chip Component Analysis

The Innogrit IG5236 is the company's first controller to support PCI-Express 4.0. It uses eight channels to maximize transfer rates and is fabricated on a 12 nm process at TSMC Taiwan.


The four flash chips are Micron 176-layer 3D TLC NAND. They have been rebranded by ADATA. Each chip has a capacity of 512 GB.


Two Samsung DDR4-2666 chips provide a total of 2 GB of fast DRAM storage for the controller to store the mapping tables.
