XPG SPECTRIX S40G RGB 4TB internal SSD

Capacity and interface

The XPG SPECTRIX S40G RGB is a 4TB internal solid-state drive built for consumers who need high-capacity storage in a standard M.2 2280 slot. It connects through a PCI-Express 3.0 x4 link using the NVME 1.3 protocol and includes an integrated heatsink to manage thermals under load. Programmable RGB lighting can be synchronised with most major motherboard ecosystems via XPG control software.

Deciding specification

The drive delivers sequential reads up to 3500 MBps and writes up to 3000 MBps on the PCIe Gen3 x4 interface, with random performance of 290000 read and 240000 write IOPS. A 2560 TBW endurance rating and 2000000-hour MTBF indicate sustained reliability for heavy workloads. Power draw sits at 0.14W idle and 0.33W active across an operating range of 0°C to 70°C.

Who this suits

Gamers, content creators and PC enthusiasts who want a single 4TB NVME drive with RGB lighting and a heatsink will find this model a direct fit. Systems limited to PCIe 3.0 or builds that prioritise Gen4 or Gen5 throughput should evaluate faster alternatives. Users without M.2 2280 support or those needing a 2.5-inch form factor must choose a different drive.
