Intel is introducing their second generation of Optane Memory products: these are low-capacity M.2 NVMe SSDs with 3D XPoint memory that are intended for use as cache devices to improve performance of systems using hard drives. The new Optane Memory M10 brings a 64GB capacity to the product line that launched a year ago with 16GB and 32GB options.
The complete Optane Memory caching solution consists of an M.2 SSD plus Intel's drivers for caching on Windows, and firmware support on recent motherboards for booting from a cached volume. Intel launched Optane Memory with its Kaby Lake generation of processors and chipsets, and this generation is intended to complement Coffee Lake systems. However, all of the new functionality works just as well on existing Kaby Lake systems as with Coffee Lake.
The major new user-visible feature for this generation of Optane Memory caching is the addition of the ability to cache a secondary data drive, whereas previously only boot drives were possible. Intel refers to this mode as "data drive acceleration", compared to the system acceleration (boot drive) that was the only mode supported by the first generation of Optane Memory. Data drive acceleration has been added solely through changes to the Optane Memory drivers for Windows, and this feature was actually quietly rolled out with version 16 of Intel's RST drivers back in February.
Also earlier this year, Intel launched the Optane SSD 800P family as the low-end alternative to the flagship Optane SSD 900P. The 800P and the new Optane Memory M10 are based on the same hardware and an updated revision of the original Optane Memory M.2 modules. The M10 and the 800P use the same controller and the same firmware. The 800P is usable as a cache device with the Optane Memory software, and the Optane Memory M10 and its predecessor are usable as plain NVMe SSDs without caching software. The 800P and the M10 differ only in branding and intended use; the drive branded as the 58GB 800P is functionally identical to the 64GB M10 and both have the exact same usable capacity of 58,977,157,120 bytes.
Everything said about the 58GB Optane SSD 800P in our review of the 800P family applies equally to the 64GB Optane Memory M10.
