ADATA Legend 850 Lite Review

The ADATA Legend 850 Lite is a budget PCIe 4.0 NVMe SSD built around ADATA's SM2269XT controller and Micron 176-layer TLC NAND.

It's a DRAM-less design running on 64MB of host memory buffer, so we'd treat it as a value pick for general storage rather than sustained heavy workloads.
