From AnandTech: Intel has finally shared the naming and specifications for their first datacenter SSDs using QLC NAND flash memory, after recently announcing that the then-unnamed drive had entered mass production. Intel is also introducing a modification to their enterprise/datacenter SSD naming scheme, and announcing a refresh to their TLC-based SATA SSDs for datacenters.
Intel's new naming system for their datacenter SSDs doesn't drastically change how models are numbered, but it does more clearly delineate between product segments, and resembles the Core i3/5/7 tiers for their consumer CPUs. The Optane DC SSDs will carry on with their current branding, but starting now all the NAND flash-based datacenter SSDs will be slotted into a D1, D3, D5 or D7 tier. From the top, we have the D7 series of NVMe SSDs for mixed workloads using TLC NAND, followed by the D5 series of high-capacity NVMe SSDs using QLC NAND, the D3 series of SATA SSDs, and the D1 series of entry-level PCIe and SATA SSDs that tend to be based on the same hardware platforms as Intel's client/consumer SSDs.
Within each tier, individual products still bear similar model numbers, so the first QLC SSD is the Intel SSD D5-P4320, compared to existing TLC-based drives like the P4510 and P4610 (the successors to which will be in the D7 series).
