physical and logical sector size

https://wiki.archlinux.org/index.php/Advanced_Format

Tools which will report the physical sector of a drive (provided the drive will report it correctly) includes

• smartmontools (since 5.41 ; smartmontools -a, in information section)
• hdparm (since 9.12 ; hdparm -I, in configuration section)

Note that both works even for USB-attached discs (if the USB bridge supports SAT aka SCSI/ATA Translation, ANSI INCITS 431-2007).
