SK hynix has introduced the updated Platinum P51 PCIe 5.0 solid-state drive (SSD) in South Korea, featuring improved specifications compared to its initial announcement in March. The new model offers a sequential read speed of 14.7 gigabytes per second (GB/s), up from 13.5 GB/s, and a sequential write speed increased to 13.4 GB/s from 11.5 GB/s. Additionally, the SSD delivers random input/output operations per second (IOPS) of up to 2,300,000 for reads and 2,400,000 for writes. These enhancements make the Platinum P51 competitive with SSDs utilizing the Phison E26 controller, especially in terms of random IOPS performance. The Platinum P51 is built with SK hynix's 238-layer 3D TLC NAND technology and has an endurance rating of up to 1,200 terabytes written (TBW) for the 2 terabyte model.

This level of endurance is consistent with other modern SSDs, although it may seem modest given the advanced NAND architecture used. Currently, the SSD is available in a 2 TB capacity, with plans to release 1 TB and 500 gigabyte versions in the future. Preliminary benchmarks conducted by Quasar Zone, a South Korean hardware website, indicate that the drive meets the manufacturer's claimed speeds, as verified by CrystalDiskMark testing.

Pricing information for the Platinum P51 has not been disclosed, making its position in the competitive SSD market unclear. SK hynix SSDs are typically priced higher than many of their competitors, which could influence the drive's market success.
