> Alignment is not necessary anymore > ..tools automatically align filesystems and partitions to the optimal 4096 byte page size Isn't 4k still very small? A quick search mentions 8k and 16 page sizes. AFAIK SSD has structures with MBs of alignment. From a quick test, fdisk seems to align to 1MiB. It should say manual alignment not necessary. > Modern SSD's usually have some built-in unallocated space for overprovisioning Were there SSDs in common use that didn't have overprovisioning?
