The Gammix S11 employs a PCI-E Gen. 3 x4 interface to allow speeds up to 3200MB/s read and 1700MB/s write while conforming to the 2280 M.2 form factor. Due to the use of 2nd generation 64-layer 3D NAND flash, higher capacities have been achieved, as well as better longevity and reliability.

If you remember back to August last year, we looked at the ADATA XPG Gammix S10, a very capable NVMe M.2 SSD that struck a great balance between cost and performance, however, more recently, XPG have shown their hand with the SX8200 which we reviewed in April; this SSD put the cat amongst the pigeons, offering 95% of the performance of a similar capacity Samsung EVO or PRO drive at 60% of the cost.
