Hi, So I bought an M2 MX300 275GB and installed it inside my Acer Nitro 791g alongside my 1TB WD Blue HDD (currently hosts my Windows 10 OS before I migrate it to the SSD). Under windows however, when I initialised the drive for the first time it reported 256GB as usable. That's the entire capacity of the drive visible through windows. I downloaded cruical Storage executive and it reports a drive capacity of 275.06 GB, how do I make windows see the extra space?

This is because Windows uses the historic definition of 1K = 1024 bytes. 1 kilobyte was standarised long ago as 1000 and 1024 is now known as a kibibyte
so a 275gb drive is 275 * 1000 * 1000 * 1000 bytes
But Windows will divide this by 1024 to get its sizes so the above / (1024 * 1024 * 1024)
= 256GB (gibibytes)
For even more fun, RAM still uses 1024 too.

Oh I see. The thing is Crucial software reports 275GB, how much would 1GB used on windows report as in the software get me? Like say I reached a pointed where all the storage was used up, would the crucial storage report that as 256/275GB or will it convert it somehow.
A bit unrelated, I heard that some space is already used by default for overprovisioning but I can't seem to figure out how much based on what you told me now. I know I can set user custom settings, but I read somewhere on this forum that some space is already taken as factory default.

Storage Exec is working in 100's
My 1TB drive (931GB to Windows)
Reports 124GB free in Storage Exec vs 115GB free in Windows
The overprovision amount has no bearing on any of this. It's at a low level and Windows is completely unaware of its existance. There's a thread on overprovisioning here if you're interested: http://forums.crucial.com/t5/Crucial-SSDs/MX300-Overprovisioning-Question/m-p/175148

There is a nice section about overprovisioning in this article.
