The ADATA GAMMIX S50 Lite 2TB SSD Review: Mainstream PCIe Gen4

Today we’re taking a look at ADATA’s XPG Gammix S50 Lite, a mid-range consumer NVMe SSD based on Silicon Motion’s new SM2267 controller. Among other notable features, the Gammix S50 Lite is the first mainstream-focused SSD that supports PCIe 4.0 – though as we’ll see in our benchmarks that support is largely incidental, as the drive’s performance is mostly the same as high-end Gen3 SSDs.
