Although it was revealed back in March this year, SK hynix new Platinum P51 PCIe 5.0 has only just now launched in South Korea and the specs have been boosted since March. The official sequential read speed is now rated at 14.7 GB/s vs. 13.5 GB/s in March and likewise, the sequential write speed has increased to 13.4 GB/s from 11.5 GB/s. We're also looking at a random IOPS read speed of up to 2,300k and random write IOPS of up to 2,400k. This compares really favourably compared to Phison E26 based SSDs, especially the random IOPS are very impressive.

However, it's not all good news, as the endurance tops out at 1200 TBW on the 2 TB SKU, which is pretty much what every other modern SSD offers today and somewhat disappointing considering that we're looking at SK hynix 238 layer 3D TLC NAND here. The 2 TB SKU is also the largest size available for now and the Platinum P51 will also come in 1 TB and 500 GB flavours. Another not so great, is the 10 W power consumption, even though SK hynix claims it's industry leading, but we know that this isn't true, as the Silicon Motion SM2508 controller is more power efficient than that. The drive has already been quickly benchmarked by South Korean hardware site Quasar Zone and it delivers in terms of the claimed speeds from the manufacturer, at least according to the CrystalDiskMark numbers. No pricing has tipped up as yet, so we'll have to wait to see how competitive the drive will be in an already crowded market. However, it's worth keeping in mind that SK hynix tends to charge a premium for its SSDs over many of its competitors.

Update Dec 14th: The 2 TB SKU has a retail price of 473,000 Korean Won, which equals about US$330, making it prohibitively expensive at the moment, even compared to most other PCIe 5.0 SSDs on the market. The 1 TB SKU comes in at 279,000 Korean Won, or about US$195. The Korean prices include 10% VAT/sales tax.
 
Hopefully the price can come down.
