The drive uses the M.2 2280 form factor, which means it is 22 mm wide and 80 mm long.
Instead of PCIe x4 3.0, Apacer has opted for a narrower x2 interface, which has a theoretical transfer rate limit of 2 GB/s.
You will find the SSD controller, four flash chips, and the DRAM chip on the PCB. The other side of the PCB is empty.
The Phison PS5008-E8 is a 4-channel SSD controller with support for TLC flash. It is designed to optimize price/performance, which is why the interface is limited to two PCIe lanes. It is produced using a 40 nm production process at UMC Taiwan.
The four TLC flash chips are made by Toshiba, using their 64-layer 15 nanometer 3D NAND production process.
A Kingston 512 MB DDR3L-1600 DRAM chip provides fast DRAM storage for the controller to store the mapping tables in.
