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 use the PCI-Express 3.0 x4 interface, the Gammix S50 Lite 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 one DRAM chip.
Chip Component Analysis
The Silicon Motion SM2267 is a four-channel flash controller with support for NVMe 1.4, TLC, and DDR3/DDR4 memory. Its biggest innovation is the support for the PCI-Express 4.0 interface.
The four flash chips are rebranded Intel/Micron 96-layer 3D TLC NAND. Each chip has a capacity of 512 GB.
A Hynix DDR4-3200 chip provides 1 GB of fast DRAM storage for the controller to store the mapping tables.
