XPG GAMMIX S70 2TB internal SSD PCIe 4.0 x4 M.2 2280 with Heatsink

Product identity

The XPG GAMMIX S70 is a 2TB internal SSD built on the PCIe 4.0 x4 interface and the M.2 2280 form factor. It uses 3D NAND flash with an InnoGrit IG5236 controller and a DDR4 cache to deliver sequential reads up to 7400 MBps and writes up to 6800 MBps. The drive targets gamers, overclockers and PC enthusiasts who need high throughput for large game libraries and content workloads.

Compatibility check

Verify that your motherboard has an M.2 slot wired for PCIe 4.0 x4 to reach the advertised speeds; the drive will fall back to PCIe 3.0 if the platform only supports that generation. Ensure the slot can accommodate a double-sided module with the pre-installed aluminium heatsink, as the terraced spreader adds height. The operating range is 0°C to 70°C, so confirm case airflow can keep the drive within those limits.

Build and daily use

The bundled heatsink uses hollow chambers and a terraced profile to increase surface area, lowering temperatures by up to thirty percent during sustained transfers. The drive is compliant with NVMe 1.4 and rated for 1480 TBW with an MTBF of 2000000 hours, indicating a high endurance ceiling for heavy write cycles. Random performance reaches 750000 IOPS for both read and write, keeping load times consistent across repeated sessions.
