ADATA XPG Gammix S11 Pro (PCIe 3.0 NVMe/3,500 MB/s Read/Classic Gen3 Gaming Drive) Review
The ADATA XPG Gammix S11 Pro is a PCIe 3.0 NVMe drive from ADATA's earlier gaming SSD generation, still relevant for anyone building or upgrading on a motherboard that only supports Gen 3.
At the PCIe 3.0 interface ceiling for speed, its included heatsink and DRAM cache make it a genuinely well-rounded option rather than a bare-minimum budget drive, a step above cheaper Gen 3 alternatives without pricing like a current-generation flagship.
Performance and Speed
3,500 MB/s read and 3,000 MB/s write are right at the top of what PCIe 3.0's interface allows, matching the fastest Gen 3 drives on the market including the SK hynix Gold P31 and ADATA's own SX8200 Pro.
Build Quality for the Tier
Including both a heatsink and a proper DRAM cache at this price point was a genuine differentiator when this drive launched, and it still holds up as a more complete package than many bare-bones Gen 3 competitors.
Comparison to Sibling Products
Against ADATA's own XPG SX8200 Pro, also covered on this site, the two share a similar performance ceiling, with this drive's included heatsink being the main practical difference. Against the SK hynix Gold P31, also covered on this site, that drive's lower power draw makes it the better pick specifically for laptops, while this drive's heatsink favors desktop use.
Who This SSD Is Actually For
Desktop builds on older PCIe 3.0-only motherboards wanting a well-rounded drive. The included heatsink and DRAM cache make this more complete than bare-budget Gen 3 options.
Buyers upgrading an existing Gen 3 system without replacing the motherboard. This drive maxes out what that platform can deliver.
Not for anyone with a PCIe 4.0 or newer motherboard. A Gen 4 drive like ADATA's own Gammix S50, covered elsewhere on this site, delivers real additional speed there.

Expert rating7.6 / 10
A well-built PCIe 3.0 drive that makes sense specifically for older platforms still worth upgrading.
Best for
- Desktop builds on older PCIe 3.0-only motherboards wanting a well-rounded drive.
- Buyers upgrading an existing Gen 3 system without replacing the motherboard.
- Anyone who wants a heatsink-equipped Gen 3 drive rather than a bare PCB option.
Not for
- Not for anyone with a PCIe 4.0 or newer motherboard. ADATA's own Gammix S50, covered elsewhere on this site, delivers real additional speed there.
- Not for laptop upgrades where power efficiency matters more than a heatsink. The SK hynix Gold P31, covered elsewhere on this site, is the better laptop pick.
- Not for buyers wanting the largest available capacities; this series tops out at 2TB.
