Micron’s client model Crucial has launched two new NVMe SSD product strains, together with their first high-end NVMe SSD which options Micron’s in-house SSD controller design. However, Crucial’s adoption of NVMe continues to lag behind most manufacturers as each new fashions are nonetheless utilizing PCIe Three interfaces whereas the high-end market is migrating to PCIe 4.
The Crucial P5 is the primary retail SSD to make use of a controller designed by Micron. Their in-house SSD controller design efforts date again not less than so far as their 2015 acquisition of Tidal Systems, however the first product with a Micron-designed SSD controller solely confirmed up a yr in the past: the Micron 2200 collection shopper OEM SSD. The Crucial P5 is a transparent step up from that, however nonetheless makes use of a PCIe gen3 interface, so it will not be setting any efficiency information and can face an growing variety of PCIe gen4 opponents because the yr goes on. However, it ought to nonetheless ship stable efficiency for all however probably the most demanding prosumer use instances, particularly because it appears like Intel will not offer PCIe gen4 host assist this yr. The P5 additionally consists of assist for all the standard encryption requirements, options which might be lacking from many high-end NVMe SSDs that focus on the buyer market solely and never enterprise prospects.

The Crucial P2 is their second entry-level NVMe SSD, however it’s not a direct substitute for the QLC-based P1. The P2 is not less than initially solely obtainable in low capacities of 250GB and 500GB, and cuts prices through the use of a DRAMless controller with TLC NAND reasonably than the P1’s mixture of cheaper QLC NAND however a controller with a DRAM cache. Micron hasn’t disclosed what controller is used on the P2, however it appears possible they’re sourcing from a 3rd social gathering as with earlier Crucial SSDs—and it may not even be the identical controller for each capacities. While each capacities have efficiency specs that fall inside the ranges we count on for a four-channel DRAMless NVMe SSD, the 500GB mannequin is definitely the slower one by most metrics. This signifies that not less than one in every of both the NAND or the controller is meaningfully completely different from the 250GB mannequin. The 500GB could be utilizing NAND components with the next per-die capability and thus not have any larger parallelism, or it might be utilizing a wholly completely different controller (or each). The 500GB mannequin’s endurance ranking can be the identical 150TB because the 250GB mannequin, which places it in QLC territory (although nonetheless higher than the 500GB P1’s 100TBW ranking).
Micron’s press launch for the P2 mentions that it is going to be obtainable in capacities as much as 1TB, however the spec sheets make no point out of the 1TB mannequin. This could also be one other scenario just like the 2TB Crucial P1 that was introduced as coming a bit later than the remainder of the lineup, however by no means hit the market.
