Everything that decides whether the SK Hynix Platinum P41 is the right drive: controller, DRAM, NAND, rated endurance, PS5 and laptop fit, and how it compares with the obvious alternatives. Hardware facts are taken from the reviews and datasheets listed at the bottom; capacities and speeds come from our comparison of 60 drives.
Who it’s for: Gen 4 builders who want flagship-class speed and efficiency: Tom's Hardware rated it the best consumer PCIe 4.0 SSD it had tested at the time. Skip it for: Anyone needing 4TB (the line stops at 2TB) or a PS5 drive without adding a heatsink — reviewers noted it runs warm bare.
| Controller | SK hynix Aries (in-house) |
| DRAM cache | Yes |
| NAND | SK hynix 176-layer TLC |
| Interface | PCIe 4.0 x4, NVMe, M.2 2280 |
| Heatsink version | Not in our data — sold bare |
| Capacity | Seq. read | Seq. write | Endurance | Warranty |

Rated endurance is 1,200 TBW at 2TB. We could not confirm the rating for the 1TB model from a primary source, so it is left blank. Speeds are the manufacturer’s sequential ratings.
Every SK Hynix Platinum P41 capacity in our comparison, smallest first.
Full list of qualifying drives: PS5-compatible SSDs.
Samsung 990 Pro: the other Gen 4 flagship with DRAM, available at 4TB.
Crucial T500: a Gen 4 DRAM drive with a factory heatsink option.
We show retail prices only while we can refresh them at least every 24 hours. For market context: TrendForce’s 16 Oct 2026 retail sample runs $133–$250 per TB for mainstream 1–2TB drives, and NAND contract prices are forecast +15 to +20% for 4Q26. Check any listing against that range with the price per TB calculator, and see the SSD price chart for the trend.
