Hello all,
I have a little question and I'm wondering if someone could help me to understand what's going on here and satisfy my curiosity...
I'm currently using a Lenovo IdeaPad 3 and Solus Budgie works like a charm on it! Solus is my true love and I really appreciate all the good job done here (thanks to the Solus team !!).
My question is about my hard drive : an SSD with 256 Go space on it... or maybe not ? As you can see on the screenshot, Gnome Disk says it's a a 256 Go hard drive (252 Go dedicated to linux system files / 4 Go for swap and 513 Mo for EFI boot)... Ok ok, this is what I thought, no matters so far ! But, when I open Gparted, it gives me VERY different numbers : 238 Go of total capacity (!) (234 Go for files / 3,73 for swap and 489 Mo for EFi boot). 18 Go have vanished ? Last software : Gnome Disk Analyzer (also available by default on Budgie) tells me I have a 246,5 Go total capacity hard drive ! Here again : 10 Go vanished...
So here are my questions : why so different numbers ? Which software should I trust ?
Thanks a lot for any good explanations on that !

Ps : as you can see I'm french native speaker, so sorry if my english is not correct !

One says Gio, one says Go (or in other words GiB vs. GB)
Gibibytes (GiB, or Gio in your locale) are bigger than Gigabytes (GB, or Go in your locale), so the capacity in Gibibytes is lower than the one in Gigabytes.

Edit: Whoops, missed your third example. In that case that's the number in Go, but without the two extra partitions shown in e.g. gparted. There still remains a difference, not sure where that's coming from.

Edit2: It seems to be the ext4 partition size minus overhead clusters (https://unix.stackexchange.com/a/751197). At least those sizes correspond on my system.

And now I realize how stupid was my question :-)) Thanks for your answer Staudey.
