It will digest hdd, ssd, nvme, direct attached memory mapped NOR ram (If you have mmap...

Ttomtom13 replied to the thread [SOLVED] Performance comparison between ZFS and LVM.OK, So maybe I will chip in some detail out of the "embedded side of computing". Situation with SSD's is VERY VERY VERY complicated. NAND flash uses very large sectors, I've seen nand chips having sectors size of ranging between 8k and 128K...
