Now, if this disk was copied byte per byte (/bin/dd) to a 4096-based disk, and Linux would start using a sector size of 4096, then I would suddenly have
The ATA drives I'm aware of report 512 byte sector size, do 512 byte I/O's but use 4K physical sectors and to get sane performance except the OS to issue sensible sized I/O requests.
