ADATA Legend 800 Review

A third Legend 800 configuration pairs Innogrit's IG5220 controller with YMTC 128-layer TLC NAND over PCIe 4.0.

Same DRAM-less HMB design as the other Legend 800 variants, just built on different silicon, so check the controller in parentheses before buying if a specific one matters to you.
