The drive uses the M.2 2280 form factor, which makes it 22 mm wide and 80 mm long. The PCB has four flash chips and the controller. A DRAM chip is not installed.
Like most M.2 NVMe SSDs, the BIOSTAR M700 connects to the host system over a PCI-Express 3.0 x4 interface.
Chip Component Analysis
We've encountered the Silicon Motion SM2263XT controller on several M.2 SSDs before. It is a fairly new model with four flash channels, solid performance, and support for DRAM-less TLC.
The four TLC flash chips are made by Intel, using their 64-layer 3D NAND production process.
