New Era of Optane M.2 SSDs Coming Quickly
Intel's Optane merchandise are at the moment in considered one of two classes. On the prime is the flagship P4800X Enterprise SSD and its derivatives for the fanatic market. On the backside are the small M.2 modules, that are primarily supposed for caching. This final class is being upgraded from PCIe 3×2 to a PCIe 3×4 host interface, transferring cache drives and small Optane SSDs extra in direction of the mainstream NVMe SSD market.
Primarily based on leaked roadmaps, we all know that the authentic Optane Reminiscence and its replace Optane Reminiscence M10 can be changed by the brand new Optane Reminiscence M15 codenamed Carson Seashore. The Optane SSD 800P can be changed by the brand new Optane SSD 815P code-named Bombay Seashore. Capability choices fluctuate barely for the M15 cache modules, which supply 16 GB to 128 GB in M.2 2280 type issue and 16 GB to 64 GB in M.2 2242 measurement. The Optane SSD 815P can be out there with the identical capacities of 58 GB and 118 GB because the 800P.
Plainly Intel is continuous the moderately complicated discrepancy between the out there capacities between the Optane Reminiscence and Optane SSD merchandise. In actuality, the Optane Reminiscence 64GB and Optane SSD 58GB merchandise have precisely the identical useable capability, and the identical goes for the 128GB versus the 118GB. The smaller marketed capacities are extra like the way in which SSD suppliers usually relate the claimed GBs to the precise usable capability, whereas the Optane Reminiscence components announce the nominal uncooked capability of their 3D XPoint reminiscence, with out the error correction used house or house out there for error to contemplate put on administration.
The system necessities for the above Optane merchandise are unchanged from their predecessors. Caching Optane Reminiscence requires a Kaby Lake platform or newer platform, and using Intel Optane Reminiscence Storage Drivers for Home windows. In any other case, each the M15 and 815P are commonplace NVMe SSDs that can be utilized as common knowledge or boot drives in any system that helps flash-based NVMe SSDs.
Optane's third new product is by far probably the most fascinating: the Optane Reminiscence H10 with Stable State Storage, codenamed Teton Glacier. The place earlier Optane reminiscence merchandise are supposed to cache a mechanical disk, the H10 is Optane caching for QLC NAND, with each 3D XPoint and flash reminiscence residing on the identical M.2 module. The H10 bundles 16 GB Optane cache with 256 GB QLC NAND or 32 GB cache with 512 GB or 1 TB QLC.
To this point, Intel has shared just one mock-up rendering that appears like an Intel 660p and Optane reminiscence module packaged on an M.2 2280 card, however with sufficient format adjustments that aren’t simple appears to be a Photoshop of pictures of the 2 current merchandise. The primary half of the board seems to comprise the identical Silicon Movement SM2263 controller used for the 660p, and one DRAM and one QLC NAND packet every. The second half of the board appears like an current Optane reminiscence module with its personal controller and 3D XPoint reminiscence packages. We're unsure if this picture is an correct illustration of the true product, however it does point out that two PCIe lanes are routed to the SM2263 controller and two to the Optane controller. This means that the Optane Reminiscence H10 seems to the host system as two totally different NVMe SSDs and possibly requires help for the PCIe port bifurcation to supply one PCIe x4 M.2 slot as two PCIe x2 slots. To function connections. This will likely presumably restrict compatibility to M.2 slots that use PCH-provided PCIe lanes. The Optane Reminiscence H10 formally requires a Whiskey Lake or Espresso Lake platform. Unofficially, this can be the primary Optane product that doesn’t perform as a typical NVMe SSD on a platform that helps NVMe. As a result of dual-controller nature of the H10, the SSD caching characteristic nonetheless is determined by driver software program and isn’t transparently managed by the SSD itself. Intel must develop a unified 3D XPoint + 3D NAND controller.
Intel has not formally introduced any of those three new Optane merchandise, however we anticipate to obtain extra official data from them quickly, and can replace this text with new particulars. The discharge of the Optane Reminiscence H10 is scheduled for spring 2019, and we anticipate the M15 and 815P to reach on the similar time or earlier.
