Today Intel is asserting updates to most of their SSD product traces. Their merchandise primarily based on 3D NAND are being up to date to make use of Intel’s 144-layer QLC and TLC NAND. On the Optane facet of the enterprise, we’ve got detailed specs for the primary product to make use of second-generation 3D XPoint reminiscence, and an up to date Optane Memory caching resolution for shopper PCs. Intel has additionally revealed the code title for his or her third-generation Optane persistent reminiscence modules, which might be launching alongside Sapphire Rapids Xeon processors.
- SSD D7-P5510 – Datacenter NVMe, 144L TLC
- SSD D5-P5316 – Datacenter NVMe, 144L QLC
- SSD 670p – Client/Consumer NVMe, 144L QLC
- Optane SSD P5800X – Datacenter NVMe, Second-gen 3D XPoint
- Optane Memory H20 – Client NVMe, 144L QLC + 3D XPoint
- Optane Persistent Memory 300 Series: Crow Pass – 3D XPoint DIMMs
Some of those merchandise have already began transport and are formally launching this month, whereas others are merely being introduced at the moment and might be launching in 2021, with full specs and pricing disclosed nearer to launch.
144L 3D NAND For Datacenter SSDs
The first two SSD bulletins are updates to Intel’s datacenter SSDs utilizing 3D NAND. The new D7-P5510 makes use of 144L 3D TLC NAND and is the successor to the D7-P5500 which makes use of 96L TLC. Since the P5500 was an OEM-only product relatively than broadly distributed via the channel, the P5510 can even function the successor to the P4510 for the portion of the client base. Intel has not introduced a 144L alternative for the D7-P5600, the higher-overprovisioning counterpart to the P5500.
Using Intel’s 144L QLC NAND is the brand new D5-P5316 SSDs in 15.36 TB and 30.72 TB capacities in both U.2 or E1.L type components. The E1.L model permits Intel to realize the unique purpose of the “Ruler” type issue by enabling 1PB of storage in a 1U server. Since the P5316 is changing the older P4326 (64L QLC and PCIe gen3), it is a way more substantial improve over its predecessor than the TLC-based P5510 is. Aside from the introduction of Intel’s third-generation enterprise NVMe SSD controller to their QLC product line, a very powerful change the P5316 brings is a serious shift in how the Flash Translation Layer works. The P5316 permits a 16x discount in DRAM by altering the SSD’s Flash Translation Layer to work with a granularity of 64kB relatively than 4kB. We’ve seen a couple of different enterprise SSDs make this type of change, comparable to Western Digital’s Ultrastar DC SN340, which makes use of a 32kB FTL granularity. The DRAM financial savings of a extra coarse-grained FTL assist make high-capacity SSDs extra inexpensive, however on the expense of severely harming efficiency and rising write amplification for small block dimension random writes. The common pattern within the business is to undertake NVMe Zoned Namespaces for such drives, stopping random writes fully relatively than counting on host software program to watch out about issuing small-block IOs. However, Intel would not appear to be able to undertake this strategy but.
Both the TLC-based P5510 and QLC-based P5316 use the identical controller platform as Intel’s different P5000-series SSDs introduced earlier this 12 months. Those drives launched Intel’s third-generation enterprise NVMe SSD controller, their first supporting PCIe 4.0. The new 144L drives do not actually push efficiency or function set any additional, however might be extra broadly obtainable and must be cheaper than the 96L drives. The TLC-based P5510 has already been sampled to clients for qualification and might be transport for income by the tip of this 12 months. The QLC-based P5316 is sampling and might be obtainable within the first half of 2021.
SSD 670p: 144L QLC For Consumers
Moving on to the patron SSD enterprise, Intel might be introducing the 670p QLC NVMe SSD within the first quarter of 2021. This…
