Three years after the announcement of the impressive Optane P4800X SSD, Intel has introduced new drives based on the second generation of 3D XPoint chips. These are Intel Optane P5800X devices that have received a new PCIe 4.0 bus with double data transfer rate. The new drives have tripled IOPS performance in mixed workloads and are 67% more wear-resistant, allowing 100 full rewrites per day.
Note that Intel has not yet revealed all the details about the next generation 3D XPoint memory. This information will appear later. So far, we can assume that the company has switched from two-layer 3D XPoint chips to four-layer ones.
The company’s declared read and write speeds reach 7.2 and 6.2 GB / s, respectively. IOPS values for random 4K blocks will be 1.5 million for reading and the same amount for writing. For mixed workloads in a 70/30 ratio, the IOPS reaches 1.8 million units. The minimum delays for reading random 4K blocks with a command queue depth of exactly one are less than 6 μs. For mixed modes of reading and writing, the delay is not more than 25 μs.
Thus, the Intel Optane SSD P5800X largely takes on the capabilities of RAM, which eliminates the modern bottleneck between the central processor and storage arrays on hard drives and SSDs.
The improved reliability and durability of the new products are also a feature of 3D XPoint memory and a source of pride for Intel. The Optane P5800X models allow 100 full rewrites per day for five years, which provides wear resistance at a write level of 584 PB. Intel Optane SSD P4800X models, we note, allowed 60 full overwrites per day for five years.
We add that at the time of the publication of the announcement, the company did not disclose the range of new products and the recommended cost. Model Intel Optane P4800X with a volume of 375 GB, we recall, at the start cost $ 1520.
