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.


Inside the box, Team Group has included a thin heat spreader foil. It has a copper core, which helps move heat around, but its mass is low, so it can't absorb a lot of heat. Our thermal testing shows that this is much too weak and that you need serious cooling for the GC Pro.

Chip Component Analysis

The Innogrit IG5666 is the company's first client-focused PCI-Express Gen 5 controller. It comes with support for eight channels and is produced using a 12 nm process at TSMC Taiwan. Internally, the controller has eight Arm Cortex-R5 cores with NVMe 2.0 support.


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


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