All storage products will display less than stated memory capacity on a computer. The discrepancy results from different algorithms.
On a computer, 1GB = 1024*1024*1024 = 1,073,741,824 (1024 is 2 to the power of 10, which is the algorithm used by the computer)
For a 16GB JetFlash, the computer will calculate it as having capacity of 14.90GB.
16,000,000,000÷1,024÷1,024÷1,024 ≒ 14.90GB.
Also note that each Flash memory may possess innate variances because of its manufacturing process. Transcend will therefore adjust the available space on the JetFlash to store necessary firmware configurations or system data. Please be assured that we do so at appropriate measures and that your JetFlash has the normal capacity.
