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 Seagate FireCuda 510 connects to the host system over a PCI-Express 3.0 x4 interface.
On the PCB, you'll find four flash chips, the controller, and two DRAM chips.
Seagate rebranded a Phison PS5012-E12 controller; it uses eight flash channels and supports 3D TLC, QLC, and PCI-Express 3.0 x4. It is produced on a 28 nm process at TSMC Taiwan.
The four TLC flash chips are made by Toshiba, built using 64-layers on a 15 nanometer 3D NAND production process.
Two SKhynix DDR4-2400 chips provide a total of 1 GB of fast DRAM storage for the controller to store the mapping tables in.
