SK hynix announced the release of Platinum P51 PCIe 5.0 series NVMe solid-state drives. The new products were first demonstrated at the GTC exhibition in March this year. They only reached the shelves now, but since then the manufacturer has improved some of the characteristics of these SSDs.

The company claims sequential read speeds of up to 14.7 GB/s for the Platinum P51 PCIe 5.0. At the time the drive was announced in March, this figure was 13.5 GB/s. Sequential write speed has also been improved, from 11.5 to 13.4 GB/s. Performance in random read operations reaches 2.3 million IOPS, and in random write operations – up to 2.4 million IOPS.
These figures make the new product the fastest M.2 consumer SSD on the market – most other solutions offer speeds of up to 14 GB/s.
The 2 TB Platinum P51 PCIe 5.0 resource is stated at 1200 TBW (terabyte of overwritten information). This is quite average for modern SSDs, which can be somewhat disappointing considering that the drives are based on SK hynix’s advanced 238-layer 3D TLC NAND flash memory chips. The maximum capacity for this series is 2 TB, while it also includes 1 TB and 500 GB models.
Independent tests of the Platinum P51 PCIe 5.0 confirm the level of performance declared by the manufacturer, at least in the CrystalDiskMark benchmark.
Information on the cost of Platinum P51 PCIe 5.0 drives is not yet available.
