Intel launches Optane DIMMs up to 512GB
By Thom Holwerda on 2018-05-31 00:54:30

Intel today announced the availability of their long-awaited Optane DIMMs, bringing 3D XPoint memory onto the DDR4 memory bus. The modules that have been known under the Apache Pass codename will be branded as Optane DC Persistent Memory, to contrast with Optane DC SSDs, and not to be confused with the consumer-oriented Optane Memory caching SSDs.

The new Optane DC Persistent Memory modules will be initially available in three capacities: 128GB, 256GB and 512GB per module. This implies that they are probably still based on the same 128Gb 3D XPoint memory dies used in all other Optane products so far. The modules are pin-compatible with standard DDR4 DIMMs and will be supported by the next generation of Intel's Xeon server platforms.

Are these supposed to speed up access to hard drives/solid state drives like the existing Optane SSDs, or can these be used as standalone storage? It's a little unclear to me what advantages these would offer over regular drives.
