Like any other hard drive you buy the capacity quoted of it is before it is formatted with a file system on it such as Fat 32, NTFS or GPT formatting.

The size or capacity if storage space left at 447Gb of free storage space is after formatting of the drive be it a SSD drive or a mechanical drive.

You always loose a set amount of GB`s in space due to the file formatting needed to be laid down on the drive for the OS in question you use to be able to read and write data to the drive Stryker.

To be honest it`s about time that drive manufacturers quoted the amount of storage space left after a drive is formatted other than quoting the raw status of the drive in capacity from factory.

Because it confuses people thinking something is...

This is absolutely normal and expected.
You are seeing the calculation differences between Base 10 and Base 2.
Read this: http://wintelguy.com/gb2gib.html and this: https://en.wikipedia.org/wiki/Gibibyte

You have not lost any drive space. Blame the confusion on the marketing department.

But it is in fact completely correct after at 447 Gb of free space after the SSD was formatted.

hello thank you for replying, thats quite a bummer to find out, i would also like to ask if thats the same case with the claimed 550mb read/write speed the ssd has because when my friend did a read/write test it only got 250+mb

Has nothing to do with write speed.
This is the same with every drive.
A box that says 1TB HDD, Windows will report it as 931GB.
2TB drive = 1.81GB in Windows.
120GB drive = 111GB.
etc.

The advertised Read/Write speed is best case, with large sequential data. What tool did he use for this test?
