Intel officially announces Intel Optane H10 with a maximum capacity of 1TB by integrating QLC and Optane memory.

Recent SSDs using QLC flash have gradually come on the market. Although these SSDs are very satisfactory in capacity, the original speed after the Cache is full is also upset. Due to the principle that QLC flash stores 4 bits of data per unit, the durability of QLC flash decreases significantly compared with the current 3D TLC and 3D MLC flash. At the same time, there is also a kind of flash with ultra-high durability, good continuity and excellent random read and write performance. It is Optane memory that uses 3D Xpoint technology. Now Intel combines QLC with Optane memory, and has officially released Intel Optane H10 series.
 
Intel claims that Optane memory H10 has ideal mixed random read-write performance at low queue depth. Combining with Optane memory technology, it can provide a reliable, large-capacity storage scheme.
It’s said that Intel combines 3D Xpoint technology with QLC through Intel Rapid Storage Technology (RST), which was previously used to speed up mechanical hard drives with small-capacity Optane memory, and was evaluated by Expreview. Although the entire Optane memory H10 has one PCIex4 interface, there are Optane memory controller and QLC flash controller on it, so the two controllers account for only two channels. As this solution does have a significant improvement in everyday applications, it makes sense for Intel to combine QLC with Optane memory technology.
In terms of performance, Intel claims that Intel Optane H10’s sequential read/write reaches 2400MB/s and 1800MB/s, and 4KB random read/write is 3200IOPS/30000IOPS, together with 55000IOPS/55000IOPS of QD2 4KB random read/write.
Optane memory H10 supports eighth-generation, ninth-generation and updated Core processor platform. According to previous news, Intel has driven both Pentium and Celeron processors using Coffee Lake core to support Optane memory, which also expands the application scope of Optane memory products.
Intel has announced three models, of which Optane memory has 16 GB and 32 GB in capacity, while QLC flash has 256 GB, 512 GB and 1 TB. The specific models are as follows.
256GB version: 16G Optane memory plus 256GB 3D QLC flash. Its durability is 75TBW.
512GB version: 32GB Optane memory plus 512GB 3D QLC flash. Its durability is 150 TBW.
1TB version: 32GB Optane memory plus 1TB 3D QLC flash. Its durability is 300 TBW.
However, Intel has not claimed the price of this product. Intel combines QLC flash with Optane memory, resulting in integrating large capacity of QLC flash with high random read and write performance of Optane memory. It is believed that Intel Optane H10 will become an appetizing product in the market.
