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 5.0 x4 is used as the host interface to the rest of the system, which doubles the theoretical bandwidth compared to PCIe 4.0 x4.


On the PCB you'll find the controller and four flash chips, two DRAM cache chips are included, too.

Chip Component Analysis

The Innogrit IG5666 son PS5026-E26 is Phison's first PCI-Express 5.0 controller. It is the company's current flagship with support for eight flash channels and NVMe 2.0, using an Arm Cortex design. The controller itself is fabricated using a 12 nanometer process at TSMC Taiwan.


The four flash chips are YMTC 232-layer 3D TLC NAND. Each chip has a capacity of 512 GB.


Two Micron DDR4-3200 chips provide a total of 2 GB of fast DRAM storage for the controller to store the mapping tables.
