is this normal for an SSD

[brandoncool32]

how it this possible 24.4gb used on ssd but when i select all the files it is only 22.4gb  how is that possible?

There is always overhead for storage.  Seems like a lot though.  Perhaps the checkbox options have something to do with it.  Not sure.  One thought I had is that the drive is mostly empty and the indexing system for the entire drive is added, so if the file was five times the size it is that extra 2gb might remain constant.

That's fairly normal, I wouldn't worry too much about it.

There will be differences due to the minimum disk space a file can use.

Your SSD may use 512 byte sectors, or 4096 byte sectors - these are the most common sizes. A file will use multiple of this sector size on the drive. 

This means that any file will use at least 512 bytes of disk space, even if there's just a few bytes.

Just the same, if the file uses 5000 bytes, it will actually use 5120 bytes on the disk (512 bytes x 10 sectors = 5120 bytes) 

 

In your case I suspect it's a combination of what I say above, and maybe some hidden files not being included in your total. 

By default, Windows doesn't show all files. You can go in the View tab and there's an options section there where you can check to view all files including system files, protected files etc
