SK hynix is set to unveil their first Gen5 consumer NVMe SSD lineup shortly, based on the products at display in their GTC 2024 booth. The Platinum P51 M.2 2280 NVMe SSD will take over flagship duties from the Platinum P41 that has been serving the market for more than a year.

Similar to the Gold P31 and the Platinum P41, the Platinum P51 also uses an in-house SSD controller. The key updates are the move to PCIe Gen5 and the use of SK hynix's 238L TLC NAND. Other details are scarce, and we have reached out for additional information.

SK hynix Platinum P51 Gen5 NVMe SSD Specifications
Capacity 500 GB 1 TB 2 TB
Controller SK hynix In-House (Alistar)
NAND Flash SK hynix 238L 3D TLC NAND at ?? MT/s ('4D' with CMOS circuitry under the NAND as per SK hynix marketing)
Form-Factor, Interface M.2-2280, PCIe 5.0 x4, NVMe 2.0
Sequential Read 13500 MB/s
Sequential Write 11500 MB/s
Random Read IOPS TBD
Random Write IOPS TBD
SLC Caching Yes
TCG Opal Encryption TBD
Warranty TBD
Write Endurance TBD TBD TBD

Only the peak sequential access numbers were available at the GTC booth, indicating that the drive's firmware is still undergoing tweaks. It is also unclear how these numbers are going to vary based on capacity. Availability and pricing are also not public yet.

This is a significant launch for the Gen5 consumer SSD market, where the number of available options are quite limited. The Phison E26 controller and Micron's B58R NAND combination is already in its second generation (with the NAND operating at 2400 MT/s in the newest avatar), but other vertically integrated vendors such as Samsung, Western Digital / Kioxia, and SK hynix (till now) are focusing more on the Gen4 market which has much higher adoption.

We will update the piece with additional information once the specifications are officially available.

    Great list of full details/specs! Impressive!

    Imagine getting free food, and then complaining about it being not as tasty as you wanted, without giving one iota of thanks for it. Incredible attitude buddy.

    Umm, suggesting that they wait a second to publish this find until the official release isn't unreasonable.

    Posting something versus waiting has long been proven a necessity to draw page views so the cannot afford to wait if they want to remain competitive. That fact is exhibited with some of the other tech sites and video channels that still publish GPU reviews. They quite literally strive to drop a review within seconds of the non-disclosure lifting.

    While AT hasn't been provided the resources from Future to do that sort of major release review work for a few years, a lot of that intensity to publish as soon as possible carries over to the lesser components like storage that Future allows as content here.

    I thought the P44 replaced the P41, and Hynix storage branding was being shelved in favor of the Solidigm merger between Hynix and Intel Storage...are they having second thoughts about spinning off into a new brand or is Hynix going to continue being the OEM brand (like Micron\Crucial)

    I hope we continue to see TLC NAND in the future.

    I suspect you'll get your wish, nandnandnand.

    I wonder why they're not making 4TB versions on any of their model lines? Thermal issues with so many layers?
