+  * Quick-commands to wipe drives and clear EFI variables
+  * Notably performs full-drive TRIMs for SSDs ([[https://wiki.archlinux.org/title/Solid_state_drive/Memory_cell_clearing|ArchWiki]])
+  * Useful to perform before OS installations
+  * Ideally use [[distros:opensuse_tumbleweed_gnome#xfce|openSUSE Tumbleweed's latest XFCE image]] on LiveUSB due to it having up-to-date tools, a GUI, and USB data persistence ((can copy a command into Terminal and run it on one machine, boot the drive on another machine, and use Terminal history to re-run the command; it's quite convenient :p))

+  * Steam and Oculus work fine with 4K sector size on Windows 10 LTSC 2021 and Linux
+  * iTunes possibly fails with 4K sectors due to Bonjour and dnssd.dll ([[https://www.techpowerup.com/forums/threads/setting-4k-sector-size-on-nvme-ssds-does-performance-actually-change.289757/page-3#post-4981622|thread]])
