Hello! I want to use ssd for storing files I work with just like a storage for saving files.
I use fdisk and I see some another look of its filesystems offer as on screenshots in all the web.

And I want to know what is '28 Linux home' file system?
Can I use it? Which advantages will I get with it instead of using usual '20 Linux filesystem'?

I see for example these:

Heyo znavko,

It's one of those systemd-only ‘standards’[0] (hence the ‘Linux’ 
misnomer).

> Can I use it?

Yes, these subtypes are mostly ignored and treated as equivalent 
the regular ‘20 Linux filesystem’ type.  I don't know what happens 
with software that predates/ignores this ‘standard’.

Their only use outside of systemd is to provide a hint for humans. 
For example, I use ‘Linux root (x86-64)’ for my root partition 
because ‘fdisk’ doesn't show partition labels by default.

None.

Kind regards,
