I'm thinking of a new build based on Z370 platform or Z390 depending on when I get round to it. Anyway, storage wise I'm thinking of using a fast NVME M.2 drive for OS and applications and possibly my Lightroom catalogues. The main images would be on a fast conventional HGST drive and working files on a SATA SSD. Would a 32GB Optane module improve the performance of accessing the files off the spinning drives? Cheers.
