Desktop hard drives can sustain anywhere from 2 to 10 times the transfer speed of USB 2.0 flash drives but are equal to or slower than USB 3.0 and Firewire (IEEE 1394) for sequential data. USB 2.0 and faster flash drives have faster random access times: typically around 1 ms, compared to 12 ms for mainstream desktop hard drives. [18]
USB drives with USB 2.0 support can store more data and transfer faster than much larger optical disc drives like CD-RW or DVD-RW drives and can be read by many other systems such as the Xbox One, PlayStation 4, DVD players, automobile entertainment systems, and in a number of handheld devices such as smartphones and tablet computers, though ...
The physical phenomena on which the device relies (such as spinning platters in a hard drive) will also impose limits; for instance, no spinning platter shipping in 2009 saturates SATA revision 2.0 (3 Gbit/s), so moving from this 3 Gbit/s interface to USB 3.0 at 4.8 Gbit/s for one spinning drive will result in no increase in realized transfer rate.
In fact, it's the fastest external USB-C SSD on the planet, period. It touts blazing-fast data transfer speeds that max out at 980MB/s, but that type of speed comes with a steep price tag.
The OWC Envoy Pro Ex USB-C External SSD is brand new, and it's the fastest external USB-C SSD on the planet right now. With max data transfer speeds that can reach a blistering 980MB/s, nothing ...

In order to market increasing drive speeds, manufacturers used the symbol n×, whereby n is the multiple of the original speed. For example, writing to a CD at 8× will be twice as fast as writing onto a disc at 4×. [2] There are two main types of disc speed, which are the angular and linear velocities.
USB 3.0 SuperSpeed – host controller (xHCI) hardware support, no software overhead for out-of-order commands; USB 2.0 High-speed – enables command queuing in USB 2.0 drives; Streams were added to the USB 3.0 SuperSpeed protocol for supporting UAS out-of-order completions USB 3.0 host controller (xHCI) provides hardware support for streams
