SSD Volume?

[Lexinious]

Hey there

I've had a few SSD's and various board's, most ROG's... Here's my question, every time I go to install Windows 7 Pro on any SSD I own (new or old) it shows below the shown gig's, how come? Example for you, my last buy was a Crucial M-500 960g SSD, when I go to install Windows ofcourse it says it makes a partition for back-up but never allows the full 960g's to be shown, it shows as 894g's, before and after install...

I understand Window's needs some space with a separate partition but I've seen that end up on 100m partition, I think 66 gigs is way to much and something else is going on, i'm truly baffled at that, does anyone know what's going on here?

Thanks in advance...

computers are based on binary math, which means storage is counted using base 2—not base 10, which is what you see on the box. So, while we measure a kilobyte as 1,000 bytes, Windows actually refers to a kilobyte as 1,024 bytes. Similarly, a megabyte is actually 1,024 kilobytes, a gigabyte is 1,024 megabytes, and so on. That means the actual amount of space on the drive is going to be lower than what you're told, with the difference being bigger as you get to bigger drives. In general, for each gigabyte reported on the box, you'll have about 70MB less space when you plug it in—which means that your 1TB drive has closer to 900GB as measured by Windows.

Thank You very much! That clears up a few years of *Head Scratching*...lol
