Note on Decimal vs Binary Units
Decimal Units (SI): Kilobytes (KB), Megabytes (MB), Gigabytes (GB), Terabytes (TB), and Petabytes (PB) use base-1000 conversion factors. 1 KB = 1,000 bytes, 1 MB = 1,000 KB = 1,000,000 bytes. This standard is commonly used by storage device manufacturers and in networking.
Binary Units (IEC): Kibibytes (KiB), Mebibytes (MiB), Gibibytes (GiB), and Tebibytes (TiB) use base-1024 conversion factors. 1 KiB = 1,024 bytes, 1 MiB = 1,024 KiB = 1,048,576 bytes. This standard is commonly used by operating systems like Windows for file size display.
Why the difference matters: A "500 GB" hard drive has 500,000,000,000 bytes (decimal), but Windows displays this as approximately 465.66 GiB (binary). This is why your storage device may appear to have less space than advertised - it's not missing space, just different measurement systems.
