I not a fan of the size naming convention. I have a 850 EVO 512gb, but the real size is 465gb. Would be nice if in these reviews you listed actual storage size. It is a shame that there isn't a standard that prevent vendors from naming a drive 1 size but delivering another.
There is a standard that nearly all storage devices have followed for decades, using standard SI prefixes...
1 gigabyte = 1,000 megabytes = 1,000,000 kilobytes = 1,000,000,000 bytes
Windows, on the other hand, reports what are actually gibibytes
1 gibibyte = 1,024 mebibytes = 1,048,576 kibibytes = 1,073,741,824 bytes
As a result, 512 GB equals approximately 477 GiB. The 850 Evo is actually advertised as a 500 GB drive though, which works out to about 466 GiB. So, the drive's stated capacity is just as described, it's just that Windows is reporting drive capacities and file sizes using what are actually binary prefixed units, when the OS should arguably be using the same units that drive manufacturers have been using to describe their storage devices for decades.
