SK hynix today unveiled the Platinum P41, the fastest M.2 NVMe SSD under the NAND flash and DRAM manufacturer's own marquee. Built in the M.2-2280 form-factor, the drive is targeted at the DIY PC enthusiast segment, and is the company's first client-segment drive to take advantage of the PCI-Express 4.0 x4 host interface. The drive combines an in-house controller design by the company, codenamed "Aries," with the company's latest 176-layer 3D NAND flash, and a DDR4 DRAM cache.

The SK hynix Platinum P41 comes in three variants based on capacity—500 GB, 1 TB, and 2 TB. All three feature a compact design. The company didn't release variant-specific performance numbers, but made broad performance claims for the series. It offers sequential reads of up to 7,000 MB/s, with up to 6,500 MB/s sequential writes, up to 1.4 million IOPS 4K random reads; and up to 1.3 million IOPS 4K random writes. The endurance claims for the 500 GB variant are 500 TBW, for the 1 TB are 750 TBW, and for the 2 TB variant are 1,200 TBW. The drives are backed by 5-year warranties. The company will release pricing and availability later into Q1 2022 (before April).

Update Jan 4th: Additional technical details on the 176-layer NAND flash can be found here and here.

Hynix also confirmed to us that the Platinum P41 uses Hynix components exclusively: "The P41 uses TLC, SK hynix Aries controller, SK hynix NAND & DRAM." This also clarifies that the drive is TLC, so there's no chance for stealth component changes to QLC like on some other vendors.
