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.

Nice. Maybe this is the dealbreaker 4.0 drive (price and/or performance wise) we've been waiting for.
 
Cant wait! Love the P31 and S31 lines!
 
If it's anything like the Gold I expect nice things with a name like Platinum! I'll be a bit disappointed if SK Hynix doesn't follow up with a equally compelling drive after the great success they had with the former.
 
Here is the specifications comparison:

MetricGold P31Platinum P41
Sequential Read3500 MB/sec7000 MB/sec
Sequential Write3200 MB/sec6500 MB/sec
Random Read570k IOPS1400k IOPS
Random Write600k IOPS1300k IOPS
Both drives have identical endurance ratings.

Fun Fact - P31 stands for PCIe 3.0 1st generation and P41 stands for PCIe 4.0 1st generation

I have a gold p31 I lost somewhere in my house.
 
Any idea how many layers the NAND they are using are? I am assuming its their 176
 
Let's hope these are as good value as their P31 counterparts but have black PCB's for all capacities. (I know I'll not be able to see it under a heat spreader, but I'll know if it's black or not!).
 
I like the look, and the specs, but its a shame that after moving to 176 layer TLC we still get limited to 2TB capacities. Sabrent has offered a 4TB TLC drive for almost a year now, and nobody else seems to bother making one. Competition is gud. Really hope we get a 4TB P41.

SK Hynix did launch the P31 with just 1TB max, so there is some hope they will increase capacity down the line. But I do agree, 2TB is just holding the line.

Sabrent just announced another 8TB M.2 drive, this one built on the E18 controller.
