In addition to the new internals, the drive includes an already attached heatsink which isn’t just there for aesthetics. On one side are the storage modules, a NANYA DRAM module (512MB total through 2x 2Gb ICs), and the controller, while the other side has another DRAM module and storage modules. Unlike our previous review on the Toshiba OCZ RC100, the ADATA Gammix drives all come in a 2280 size and use both sides of the PCB. Also updated is the NVMe protocol moving from 1.2 to 1.3. This combination of controller and NAND improves performance significantly over the outgoing SM2260 based models (Gammix S10, XPG SX7000/8000). The XPG Gammix S11 uses the latest Silicon Motion SM2262 controller and pairs it with 2nd generation 64-layer Micron 3D TLC NAND. Generationally, the S11 differs from the S10 in both the controller used as well as the NAND. The S11 outperforms the S10/SX8000 from last year due to the new internals. For example, the 240 GB drive is rated at 3200/1100 MB/s Reads/Writes with 200K/240K IOPS while the 480 GB and 860 GB models run 3200/1700 MB/s with 310K/280K IOPS. The ADATA Gammix drives comes in three capacities – 240 GB, 480 GB, and 960 GB with performance scaling up as the capacity increases. Read on to see how the Gammix S11 fared in our testing. We were able to put the drive through our testing suite and see if the paper specs match up with actual results. The S11 should run a bit cooler with the heatsink and performance should be in the same ballpark. The main difference between the two are the included heat spreader on the S11 and branding, but under the hood contain the same bits including the Silicon Motion SM2262 controller and Micron 2nd generation 3D TLC NAND. The Gammix S11 shares the same internals and specifications with the SX8200 but differ on a price level with the S11 costing a bit more. The modules are able to reach speeds up to 3200MB/s sequential reads and 1700 MB/s on writes which, on paper, places it up there with other enthusiast level drives. The Gammix series of products are typically part of a higher performance line and the Gammix S11 drive is no different. Today we get an opportunity to look at another M.2 NVMe based SSD in the ADATA Gammix S11.
