NTFS disk compression and correct file sizes?

Question

NTFS

Tell me, who knows the topic, there is a capacious hdd on the server, it’s all full of large files of 7-8GB each.
I set NTFS compression, won 10%, the recording is barely going on, but you don’t need to write anything there, and reading seems to have remained at the same level. Is it worth it or return it the way it was?
The linux command: ls -sh began to show the size of the compressed file, is it possible for it to show the real size?

Answer 1

the recording is barely going

This is weird.
Usually on the HDD, due to compression, performance only increases, because reading from a slow disk is reduced, and the overhead is offset by the good power of modern processors.
She shows everything right. The uncompressed size is a file attribute that is registered only in NTFS. Maybe there is a way to get it out of there, but definitely not using standard Linux tools.

Answer 2

The behavior you describe is correct. A 403 error will be thrown if a user profile tries to view a user who has neither the USER role nor the ADMIN role.
