USB 3.0 flash drives are not necessarily faster than USB 2.0 versions, even though they have a more advanced interface, because the internal components may be identical to those in the older versions, according to user reports and data from tests on particular makes and models of the drives.
Several inexpensive USB 3.0 drives turned out to have USB 2.0 components inside, and some even used components also found in iPhone 8 devices, according to an analysis by Hackaday.
The inconsistency of internal components means that USB 3.0 drives are not always faster, even though the specification theoretically allows for data transfer speeds of up to 5GBps.
This news may be a concern to companies purchasing such drives in bulk for office use, and for consumers who want to purchase a drive that will perform at higher data transfer rates.
