  • Use sg_format to run a low level format on the disk. 512E vs 4kN isn’t going to change much in a homelab environment. If you create a filesystem with 4k clusters, Linux will send 4k wrudte blocks to the disk. The firmware on the disk will write that out into 8 logical disk sectors, usually in a single 4k physical sector. I use my storage mainly for media and there’s no performance difference between my 512E disks and my 4nN disks. I simply don’t have an intense and sensitive enough environment to show the performance gain. I’d say leave the low level formating alone and just write a filesystem on top of it with 4k blocks.
