SK hynix Platinum P41 - M.2 PCIe Gen4 NVMe SSD - 500GB
About SK hynix Platinum P41 - M.2 PCIe Gen4 NVMe SSD
The SK hynix Platinum P41 is SK hynix's flagship Gen4 consumer NVMe SSD. It uses SK hynix's in-house Aries controller, 176-layer TLC NAND, and a dedicated LPDDR4 DRAM cache. Sequential speeds reach 7,000/6,500 MB/s read/write on the 1TB and 2TB models, with the 500GB at 7,000/4,700 MB/s. This puts it firmly in the top tier of Gen4 alongside the Samsung 990 Pro.
In-House Everything
SK hynix is one of the few SSD manufacturers (alongside Samsung) that designs its own controller, manufactures its own NAND, and packages its own DRAM. The Aries controller is purpose-built for the P41, and the vertical integration shows in power efficiency. The P41 draws less power under load than most Gen4 competitors, making it a strong laptop option.
Performance Tier
The P41 competes directly with the Samsung 990 Pro. Both have dedicated DRAM, both push near Gen4 bandwidth limits, and both deliver consistent random I/O under mixed workloads. Independent reviews from Tom's Hardware and TechPowerUp have placed the P41's sustained write performance (after SLC cache exhaustion) among the best in the Gen4 class. Random I/O hits 1,400K/1,300K IOPS across all capacities.
Endurance
500 TBW (500GB), 750 TBW (1TB), 1,200 TBW (2TB). Five-year warranty. Available in 500GB, 1TB, and 2TB only.
Best for: Gen4 builds where you want DRAM-backed performance with excellent power efficiency. One of the best Gen4 NVMe drives for laptops. Competitive with the Samsung 990 Pro at every price point.
Avoid if: You need more than 2TB. The P41 maxes out at 2TB while competitors offer 4TB and 8TB. The Samsung 990 Pro and Crucial T500 are better choices if capacity is a priority.
