Intel Optane DC P4800X with 3D XPoint Offers 21x Endurance Over MLC NAND
Intel is readying a fleet of new SSDs based on its new 3D XPoint non-volatile memory, a technology that Intel hopes will replace NAND flash in the years to come. The company developed this technology in collaboration with Micron Technology, under its IMFlash Technologies banner. The first Intel SSDs with this memory will be sold under the Optane brand. There are several sub-brands targeting the various market segments (client, enterprise, data-center, etc.), and technical slides of the data-center targeted Optane DC P4800X SSD were leaked to the web.
One of the first Optane DC P4800X SSDs comes in a rather measly capacity of 375 GB. The drive is built in the half-height PCI-Express add-on card (AIC) form-factor, with PCI-Express 3.0 x4 host interface. The drive belts out sequential transfer rates of up to 2400 MB/s reads, with up to 2000 MB/s writes, which may not sound like much given that even TLC NAND flash based PCIe 3.0 x4 drives offer higher transfer rates; until you look at three key metrics - latency, random-access performance, and endurance.
