Note that all of these technologies, HDD, SDD, M.2, report different things and don't always report them the same way. This is an SDD in my Plex backup server: mark@science:~$ sudo smartctl -x /dev/sdb [sudo] password for mark: smartctl 7.2 2020-12-30 r5155 [x86_64-linux-5.15.0-69-generic] (local build) Copyright (C) 2002-20, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: Crucial/Micron Client SSDs Device Model: CT250MX500SSD1 Serial Number: 1905E1E79C72 LU WWN Device Id: 5 00a075 1e1e79c72 Firmware Version: M3CR023 User Capacity: 250,059,350,016 bytes [250 GB] Sector Sizes: 512 bytes logical, 4096 bytes physical In my case the physical block is 4096 bytes but addressable in 512 byte blocks.
