Intel releases Optane Memory H10 specification

H10 is basically an existing Optane Memory M10 module and Intel 660p QLCSSDIntegrate into a single drive. The Optane portion serves as a cache for the QLC portion, using the M.2 modules and mechanical hard disks previously recommended by Intel for stand-alone optane memoryWindowsOptiane memory cache driver. So far, Optane products are hard to adapt to superbooks, and installing two M.2 slots in them can be challenging.

Optane Memory H10 has three types, QLC NAND capacity ranging from 256GB to 1TB. The 256GB model will have 16GB of Optane storage capacity, while 512GB and 1TB will have 32GB of Optane storage capacity. All three capacities are implemented as unilateral M.2 modules. About half of the cards are dedicated to Optane controllers, media and PMI. The other half includes Silicon Motion SM2263 controllers, DRAM and QLC NAND.

The card as a whole has a PCIe 3.0x4 interface, but each of the two SSD controllers has only two PCIe channels. Intel's caching software will support both reading and writing data from Optane and QLC, so they rated H10 as 2.4 GB/s sequential reading, even though neither of them can read or write more than 2 GB/s separately.4KB randomly reads QD1 32K IOPS, QD2 55k IOPS, and 4kB randomly writes QD1 30K IOPS and QD2 55k IOPS. Write endurance 300 TB. The total idle power is less than 15 mW, with a five-year warranty.

Intel requires H10 to be used with 300 series PCH and 8th generation core U series mobile processors. Intel has not yet promised to use H10 in the retail market for desktop systems, but many 300 series motherboards have firmware updates that can be started from H10.
