The Intel Optane Memory H10 Review: QLC and Optane In One SSD
> The Optane Memory H10 does not introduce any new ASICs or any hardware to make the Optane and QLC portions of the drive appear as a single device. The caching is managed entirely in software, and the host system accesses the Optane and QLC sides of the H10 independently. Each half of the drive has two PCIe lanes dedicated to it.
Could work, but alas.
> Compatibility with older platforms and non-Intel platforms is mostly as expected, with only the NAND side of the H10 accessible—those motherboards don’t expect to find two PCIe devices sharing a physical M.2 x4 slot, and aren’t configured to detect and initialize both devices.
