About Hi-Speed USB 2.0
Your Toshiba 3.5" Drive is equipped with a Hi-Speed USB 2.0 interface. 
USB (Universal Serial Bus) is serial data transmission technology. The 
original standard (USB 1) could transmit data at speeds of up to 
12 Mbps (Megabits per second). USB 2.0 has a maximum throughput 
of 480 Mbps—that’s up to 40 times faster than USB 1. 
Interface transfer rates up to 480 Mbps
USB 2.0 can transfer data at speeds of up to 480 Mbps. However, 
data transfer rates will depend on a number of factors, including 
available CPU resources, and the number of USB devices attached 
to your computer. Also, as with any data I/O (input/output) 
technology, some bandwidth is taken up by the data protocols 
that structure and govern data transmissions. In day-to-day use, 
you can expect maximum sustained transfer rates in the low to 
mid-30s MB/s (Megabytes per second).
