The SK Hynix Platinum P41 is a solid-state drive in the M.2 2280 form factor, launched on May 11th, 2022. It is available in capacities ranging from 500 GB to 2 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the SK Hynix Platinum P41 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the Aries (ACNS075 PHC633.00S-2) from SK Hynix, a DRAM cache chip is available. SK Hynix has installed 176-layer TLC NAND flash on the Platinum P41, the flash chips are made by SK Hynix. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The cache is sized at 213 GB, once it is full, writes complete at 2250 MB/s. Copying data out of the SLC cache (folding) completes at 1500 MB/s. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The Platinum P41 is rated for sequential read speeds of up to 7,000 MB/s and 6,500 MB/s write; random IO reaches 1400K IOPS for read and 1300K for writes.
At its launch, the SSD was priced at 150 USD. The warranty length is set to five years, which is an excellent warranty period. SK Hynix guarantees an endurance rating of 750 TBW, a typical value for consumer SSDs.
