Intel's Optane H10 marries 3D XPoint with NAND flash
by from Techreport on (#46K63)
Hybrid storage is nothing new. Back in the early years of SSDs going mainstream, some companies started to make drives and systems that sought to combine the blazing speeds of NAND flash with the cheap capacity of good old magnetic storage. There are basically two ways to go about this. The first is to just shove some NAND into an HDD and develop a controller smart enough to coordinate access between the flash and the rust, as Seagate did with its SSHD line. The second is to use physically distinct SSD and HDD devices, but present them as a single logical volume with some kind of software running the show. This is how Apple's Fusion Drive tech works.
