3D XPoint Storage On The Way

The Optane Memory M15 addresses both the capacity and performance challenges associated with the first-gen products. The M15 comes with a doubled peak capacity of 64GB, but also comes in the same 16GB and 32GB capacities as its predecessor (all in an M.2 80mm form factor). Intel also widened the data pipe from a PCIe 3.0 x2 connection to x4, allowing access to twice the bandwidth. Intel's new proprietary controller doesn't fully saturate the bus though, but peak sequential read speeds improved by 550 MB/s, now reaching 2 GB/s, and write speed improves to 900 MB/s. Random performance also jumps considerably to 450,000/220,000 read/write IOPS.

The Optane Memory M15 seems to address some of the concerns of the relatively tiny (capacity wise) and limited performance of the first-gen models, but we don't have pricing or availability information yet. Stay tuned.
