The Drive

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


PCI-Express 4.0 x4 is used as the host interface to the rest of the system, which doubles the theoretical bandwidth compared to PCIe 3.0 x4.


On the PCB you'll find the controller and four flash chips, a DRAM cache chip is not available.


Lexar's sticker uses a white sticky tape that makes contact with the chips and has a shiny metal foil on top of that. This means less heat transfer, because heat has to travel through the white plastic adhesive first. The metal foil is also rather thin.

Chip Component Analysis

The Innogrit IG5236 is the company's first controller to support PCI-Express 4.0, released in 2020. It uses eight channels to maximize transfer rates and is fabricated on a 12 nm process at TSMC Taiwan.


The four flash chips are Intel QLC NAND with 144 layers. Each chip has a capacity of 1 TB.
