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 two flash chips, a 2 GB DRAM cache is present.


Lexar's heatsink uses four screws, which ensures a good connection between SSD and thermal pads.


Inside the heatsink enclosure we find a regular NM800 Pro SSD, even including the sticker.


Thick thermal tape ensures there's good contact between drive and heatsink.

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 two flash chips are Micron 176-layer 3D TLC NAND. They have been rebranded by Longsys. Each chip has a capacity of 1 TB.


A single Foresee LPDDR4x chip provides 2 GB of fast DRAM storage for the controller to store the mapping tables.
