Question My free space magically disappears when i tried to move files into them (instantly, magically disappears)

In extreme cases even if i have for example 200gbs of free space i'd end up having to copy the files multiple times in small chunks due to my windows explorer registering the free space as much less than enough.

And i only realize recently that it only happens to my SSDs, not the high end expensive ones like Samsung 970 Evo though. It's as if i paid for 1TB SSDs only to get 900-something gigs, same goes for my 512 one being 470-ish with about 440 usable.

My Spec is as follows :
Asrock A320M-HDV (updated Bios)
Ryzen 5700G
RX 6800 16GB
Team Elite 2x8GB
Windows 10

SSDs in questions :
T-Force 512GB
KYO Kaizen 1TB
Samsung Evo 970 256GB
And not only the "disappearing free space" the SSDs transfer speed are so much slower than most advertised, a noticable improvement from HDDs but 30~100MBs on a good day is, sad. I also can't get my windows to run on safe mode (no booting loading screen, just the windows logo indefinitely)
I've tried reinstalling windows, running chkdsk at the moment. Thank you in advance for any kind of assistance.

Look using Disk Management (open via "Create and format hard disk partitions).

Expand the window so all can be fully seen and read.

Take a screenshot and post the screenshot here via imgur (www.imgur.com > green "New post" icon).

Disk Management provides a much improved view of disks, partitions, and sizes.

Your C and F drives have far too little free space available.
This contributes to the 'slow'.

It's as if i paid for 1TB SSDs only to get 900-something gigs,

That is normal and to be expected.
A drive advertised as "1TB" shows as 931GB in Windows.
Nothing is 'missing'.

You are running your C drive with 60 GB of free space, moreover on a cheap drive from a shady Indonesian brand. Problems have to be expected.

Thank you for clearing this up, i'm just a bit baffled by that fact, never have i ever have to deal with this kind of problem with HDDs, felt like i was being gaslit by my own storage or something.

And even for shady brands, they're still somewhat passable in SSDs tierlist sense, i should've known better and chose Samsung still.

SSDs work with memory cells that store data like a big spreadsheet and if almost all the cells are occupied, the drive has a hard time to find empty spaces to write new data or store temporary bytes so it gonna have to use its cache for every operation. It's particularly bad for a C drive that constantly read and write files. It's recommended to leave at least 20% of free space on a drive.

I would also never cheap out the system drive. Doesn't matter much if it's just for storage but the system drive should be a quality one from a well known brand.
