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.

Questions about this item

Does the XPG GAMMIX S70 2TB include a heatsink or do I need to buy one separately?

The drive ships with an integrated aluminium heatsink that uses a terraced structure and hollow chambers for airflow, so no separate cooler is required.

Should I choose the 2TB version or a different capacity for best endurance?

The 2TB model is rated for 1480 TBW and 2,000,000 hours MTBF, giving higher total write endurance than smaller capacities in the same series.

Will I actually see 7400 MB/s reads on my PCIe 4.0 motherboard?

Sequential reads up to 7400 MB/s are possible on a PCIe 4.0 x4 slot with NVMe 1.4 support; on a PCIe 3.0 slot speeds will be limited to the 3.0 ceiling.
