Packaging
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 SSD controller and two flash chips. A DRAM cache is not available.
Netac includes an optional heat spreader with their drive. If you plan on using your motherboard's M.2 heatsink, no need to install it, otherwise you should definitely install it.
The heat spreader contains a thin metal layer, which helps with heat transfer.
Chip Component Analysis
MaxioTech's MAP1602A controller is produced on TSMC's 12 nanometer node and uses several Arm Cortex R5 CPU cores.
The two flash chips are YMTC 232-layer 3D TLC NAND.
