With the Platinum P51, SK Hynix’s first mainstream PCIe 5.0 SSD is approaching its market launch. This applies at least to the domestic market of South Korea, where the first editorial team has already received a sample. These, as well as local retailers, provide further details on the very fast SSD with components from a single source.
SK Hynix wants to beat Phison’s E26 with P51
The Platinum P51 starts with 14,700 MB/s read and 13,400 MB/s write, two maximum values for sequential transfer. The fastest SSDs powered by Phison’s E26 controllers to date aren’t just outperformed in sequential throughput. The maximum IOPS is an entire league higher, at over 2 million. At least according to the marketing slide, the latencies are very low, at best 33 µs for read access and 10 µs for write access.
The Quasarzone editorial team received a 1TB sample which, according to the screenshot, achieves at least 14,600 MB/s read and 13,200 MB/s write, which is slightly lower than the key figures announced . A full test will follow.

There are other details, citing information from an online store. The Alistar controller is supported by LPDDR4 as cache and 238-layer TLC NAND. All these components come from SK Hynix. Like Samsung and Micron, this manufacturer is capable of it.
Power consumption is given as 10 watts at any given time. This would be slightly less than SSDs equipped with E26 controllers, which reach up to 12 watts.

However, it is unclear when the SK Hynix Platinum P51 will be available. An introduction at CES 2025 is possible, but this has not yet been confirmed at the request of the editors.
