The drive uses the M.2 2280 form factor, which makes it 22 mm wide and 80 mm long.
Like most M.2 NVMe SSDs, the Lexar NM700 connects to the host system over a PCI-Express 3.0 x4 interface.
On the PCB, you'll find the controller and two flash chips, a DRAM cache chip is installed, too.
Chip Component Analysis
The eight-channel flash controller is made by Marvell. Once a leader in SSD controller chips, seeing one of their chips on a modern SSD is quite rare. Their 88SS1092 was released around 2018. Internally, it uses a triple-core ARM Cortex R5 controller running at up to 500 MHz.
The two flash chips each have a capacity of 512 GB. They have been rebranded by Longsys, Lexar's parent company, which buys up bulk unpackaged flash chips, tests them in their facilities, and packages them.
A Nanya DDR3-1866 chip provides 1 GB of fast DRAM storage for the controller to store the mapping tables in.
