SK hynix announces Platinum P41 PCIe 4.0 SSD with 176-layer NAND

Maxing out PCIe 4.0 x4 bandwidth.

SK hynix has launched a new SSD called Platinum P41 using an in-house Aries controller and running off a PCIe 4.0 x4 interface.

The Platinum P41 arrives in 500GB, 1TB or 2TB capacities, all boasting 7GB/s read and 6.5GB/s write speeds, so pretty much maxing out available PCIe bandwidth when factoring in transmission overheads. Data is stored in 176-layer 3D NAND flash memory, whose cell level is not disclosed but most likely TLC.

Regarding random operations, SK hynix advertises 960K IOPS read and 1,000K IOPS write for the small 500GB drive, alongside 1,400K IOPS read and 1,300K IOPS write for the bigger brothers.

Durability-wise, these SSDs are rated at 500, 750, and 1200 TBW for the 500GB, 1TB and 2TB versions, respectively. For the 500GB variant, that is nearly three years of continuous drive filling each day.

SK hynix also said that the P41 undergoes 1,000 hours of high-temperature operating life (HTOL) testing to ensure reliability, where it has achieved an extensive 1.5 million hours in mean time between failures (MTBF).

The Platinum P41 ships with a five-year warranty and will set you back $104.99, $149.99 and $259.99 for the 500GB, 1TB, and 2TB models, respectively.
