April 29, 20206 yr Hi, Currently using a 500GB nVME for cache and have just removed a 250GB SSD for my PC and was wondering can I add the SSD to the cache? If so does it fill one drive up then the other when space run out on 1 cache drive? Thanks

If so does it fill one drive up then the other when space run out on 1 cache drive? Thanks Can you? Yes. Should you? No. The (multi-drive) cache pool is RAID-based (BTRFS RAID). So either you will have 250GB available space (RAID-1) or 500GB available space (RAID-0). I.e. no improvement. A better option is to mount the 250GB as unassigned and use it for write-heavy activities (e.g. temp download files). That will enhance the life span of both drives and still give you more storage space.
