FAQ: KTM-030615-HYX-03
This is common for flash storage, whether internal SSD or external USB storage, and is due in part to a variance in how flash memory vs spinning platter hard drive manufacturers calculate megabyte. Hard drive manufacturers calculate a megabyte (or 1,000x1,000 bytes) as 1,000KBs, whereas the binary calculation for flash-based storage is 1,024KBs.
Example: For a 1TB flash-based storage device, Windows will calculate it as having a capacity of 931.32GB. (1,000,000,000,000÷1,024÷1,024÷1,024=931.32GB).
Furthermore, Kingston reserves some of the listed capacity for formatting and other functions such as firmware and/or controller-specific information, and thus some of the listed capacity is not available for data storage.
