western digital was the parent, they bought sandisk in 2016.
last year they spun-off the flash storage business back into a new entity (also) named sandisk, leaving western digital (‘wd’) with only the traditional hdd business.
the spin-off also included wd’s previous sd card line as well as their popular computer ssd products (which are being re-branded by the ‘new’ company).

my first install of debian was before it had names. my most recent was last tuesday. i’ve strayed for short stints, but debian is where it’s at. i do have a couple ‘others’ but they are special setups for specific things.
if you like the deb-based system but want to get away from canonical, trixie is ready to rescue you.
