About capacity:
The displayed capacity is not equal to the nominal capacity. Manufacturers of Flash (memory) or hard disk devices generally use 1000 as the base, that is, 1KB=1000 Bytes, 1MB=1000KB, 1GB=1000MB, and the operating system is based on 1024 to calculate the capacity 1KB=1024Bytes, 1MB=1024KB, 1GB= 1024MB, the formatted capacity will be smaller than the nominal capacity. Under different operating systems, system files and firmware will also occupy a small amount of space, but the actual space used must be greater than or equal to 90% of the nominal capacity.
16GB=approximately 14.4GB-14.8GB
32GB=approximately 28.5GB-30GB
64GB=approximately 58GB-60GB
128GB=approximately 113GB-124GB
