Intel have officially launched their Optane Memory product. To quote HotHardware's coverage: The Intel Optane Memory devices we’ll be discussing here looks like other current generation 80mm M.2 “gumstick” type solid state drives. However, Intel Optane Memory is meant to be used as an accelerator for systems featuring relatively low-speed storage devices, like hard drives. More coverage on Tweaktown, Tech Report, LegitReviews, Anandtech and PC Perspective. I haven't read the articles in depth yet, but my first thought is that I can't really see the point of it. Is it meant to be like ReadyBoost but on M.2 PCIe? It'd have to be pretty cheap, otherwise you could just buy one of the many large/fast M.2 PCIe SSDs and put your data on that. Unless you have a huge data set on HDD.. hrrm.
