XPG GAMMIX S70 1TB PCIe 4.0 SSD

The XPG GAMMIX S70 is a 1TB internal solid state drive built for consumer desktops and laptops. It uses an M.2 2280 form factor and connects through a PCI-Express 4.0 x4 interface. The drive targets gamers, overclockers and PC enthusiasts who need fast storage for large game libraries and heavy workloads.

Aluminium heat spreader with terraced design

An aluminium heat spreader with a terraced structure and hollow chambers ships attached to the drive. This design increases surface area and airflow to lower operating temperatures by up to thirty percent. The SSD is rated for an operating range of 0°C to 70°C and a storage range of -40°C to 85°C.

NVMe 1.4 compliant with 740TB endurance

The drive complies with NVMe 1.4 and uses 3D NAND flash paired with an InnoGrit IG5236 controller. Endurance is rated at 740TB written and MTBF at 2,000,000 hours. The M.2 2280 form factor fits standard motherboard slots and the PCIe 4.0 x4 interface remains backward compatible with PCIe 3.0 platforms.

Questions about this item

How do I install the M.2 2280 GAMMIX S70 into my motherboard slot?

Insert the drive at an angle into the M.2 2280 slot, press it flat, and secure it with the motherboard screw; the pre-attached aluminum heat spreader must stay in place to keep temperatures down.

When will the 1TB GAMMIX S70 reach its rated endurance limit?

The drive is rated for 740TB of writes, which typical consumer workloads reach after several years of heavy daily use.

What stops the GAMMIX S70 from sustaining its 7400 MBps read speed during long transfers?

The controller throttles performance once the drive temperature approaches the 70°C operating limit, even with the aluminum heat spreader.
