GAMMIX S11 Pro 1TB NVMe SSD with heatsink

This internal solid-state drive uses a PCIe 3.0 x4 interface and NVMe 1.3 to reach sequential reads of 3500 MB/s and writes of 3000 MB/s. It is built for gamers, overclockers and rendering professionals who need sustained speed. The integrated heatsink lowers drive temperature by up to 10 °C.

PCIe 3.0 x4 interface limits real-world throughput

The bus caps sequential bandwidth near 3500 MB/s read and 3000 MB/s write, so heavier workloads cannot exceed that ceiling. Random performance tops out at 390000 IOPS read and 380000 IOPS write. Endurance is rated at 640 TBW with a 2000000-hour MTBF.

Check M.2 2280 slot and heatsink clearance

Verify the motherboard has an M.2 2280 key-M slot wired for PCIe 3.0 x4 and NVMe 1.3. Ensure the heatsink fits under any motherboard shield or graphics card backplate. Confirm the BIOS can boot from an NVMe drive before installing.

Questions about this item

Should I pick the 1TB GAMMIX S11 Pro or a smaller capacity?

The 1TB model delivers up to 3500 MB/s sequential read and 3000 MB/s write with 640 TBW endurance, so it suits heavy gaming and rendering workloads better than lower-capacity variants.

What do the 3500/3000 MB/s figures mean once the drive is installed in my PC?

Those are peak sequential speeds over the PCIe 3.0 x4 link; real-world throughput depends on your motherboard's M.2 slot wiring, thermal headroom and the workload mix you run.

Does the PCIe 3.0 x4 NVMe 1.3 interface cap performance in practice?

The four-lane Gen 3 ceiling sits near 3500 MB/s read, so this drive already saturates the bus; a PCIe 4.0 platform would not raise its sequential numbers further.
