At its Memory and Storage Day 2019 in Seoul last week, Intel made several announcements concerning its Optane persistent storage as well as NAND flash capacity.
Optane is a new form of non-volatile memory from Intel that has the storage capacity of a solid state drive (SSD) but speed almost equal to DRAM. It sits between memory and storage to act as a large, fast cache. While some come in a PCI Express card design, the predominant design is DRAM memory sticks that plug into the motherboard. And they cost a fortune. A 512GB Optane stick will run you $8,000.
Intel announced a new generation of Optane memory codenamed “Alder Stream,” which it said has a 50x lower failure rate than 3D NAND and also triples the transfers per second compared to the current generation of Optane on the market today.
