| Q1:
Why is the available actual capacity of UFD device less than the amount indicated on the package?
|
A: The differences in the display of capacity are the results due to the calculation of the computer operating system differs from the way of the storage device through the Controller IC. The storage device is usually calculated in the decimal system, while the computer operating system is calculated on the basis of the binary system.
The calculation of the storage device: 1TB=1000GB, 1GB=1000MB, 1MB=1000KB, 1KB=1000Bytes.
The calculation of the operating system: 1TB=1024GB, 1GB=1024MB, 1MB=1024KB, 1KB=1024Bytes.
For example, a storage device marked with having 128GB capacity, 128GB=128*1,000*1,000*1,000=128,000,000,000Byte. But, the computing unit of the computer calculation is a binary system, so the 128GB calculated by the storage device is converted into bytes, 128,000,000,000Bytes, so what will be displayed through computer\'s calculation method is 128,000,000,000/1024/1024/1024≒119GB.
The fastest way to calculate: The capacity labeled on the product x 0.93is about equal to the actual capacity recognized in the computer. |
| Q2:
Are USB3.0 and USB3.1 the same?
|
A: USB3.1 is a specification developed by the USB Association, and it can be divided into USB3.1 Gen1 and USB3.1 Gen2.
