Editor Notes
Overview
The SK Hynix Platinum P41 launched in 2022 as a PCIe 4.0 successor to the Gold P31. It uses SK Hynix's ACNS075 (Aries) controller and 176-layer 3D TLC NAND—both in-house—with LPDDR4 cache. Sequential read tops at 7,000 MB/s for the 1TB and 2TB models, which is close to the practical PCIe 4.0 x4 ceiling.
The P41 drew favorable comparisons in reviews to Phison E18-based drives (very common at the time), with consistent sustained write performance noted alongside the high TBW ratings inherited from the P31 line: 750 TBW for the 1TB model. It is available in 500GB, 1TB, and 2TB capacities.
