Samsung could be ready to announce an exciting new SSD.

As spotted by @KOMACHI_ENSAKA, PCI-SIG has updated its Integrators List (a list that “includes all products that have successfully completed the rigorous testing procedures of the Compliance Workshop”) with the 990 PRO, a new SSD from Samsung. The spec revision column can confirm that this is a “PCIe 5.0 at 32 GT/s” drive with x4 bandwidth, and while there’s no indication of what exact M.2 size it might be, its predecessor would suggest the 2280 form factor.

The speeds for Samsung’s 990 PRO are also somewhat of a mystery, but if it’s anything like the company’s PCIe Gen 5 PM1743 enterprise SSDs, 3,000 MB/s random speeds and IOPS of up to 2,500 may not be outside the realm of possibility, as VideoCardz pointed out in its coverage, alongside the expected compatibility.

The Gen5.0 storage can be utilized by some Intel Alder Lake systems and will soon available for all X670 and B650 AMD AM5 motherboard series. While PCIe 5.0 conformity for AMD 600-seires chipset is optional for the GPUs, all mid-range and high-end motherboard series should support the Gen5 storage with at least one M.2 slot.

Samsung’s top NVMe SSD for consumers at the moment is the 980 PRO PCIe 4.0 NVMe SSD. It’s available in capacities ranging from 250 GB to 2 TB, the latter of which features sequential read speeds of 7,000 MB/s and sequential write speeds of 5,100 MB/s.

The 980 PRO PCIe 4.0 NVMe SSD is also available in 2 TB and 1 TB SKUs that come with a heatsink, which, as Samsung advertises, is PlayStation 5 compatible.

  1. Still pissed about the 980 Pro being called "Pro" when it had TLC instead of MLC.
    TLC is the new MLC... QLC is the new TLC ;)

    All else equal, the push to higher density is overcoming the performance advantages of purposefully lower-density flash it seems.

    I don’t mind them selling TLC and QLC drives, I just don’t really want them. A 512GB SLC drive would be fantastic though
  3. I haven't had any issues with a single Samsung drive to date.
    I didn't even get into SSDs until Samsung came out with their V-NAND. An 850 Pro was my very first SSD.

    I'd still like to get my hands on a 3D XPoint drive. Wish Intel was still making consumer versions of Optane drives.
