Went shopping lately for a new USB device lately? Do you know that some USB 2.0 devices are faster than others?
Which do you buy? A Full Speed or High Speed USB drive? This article tells it all:
———-
USB supports three data rates:
A Low Speed (USB 1.1, USB 2.0) rate of 1.5 Mbit/s (187 kB/s) that is mostly used for Human Interface Devices (HID) such as keyboards, mice, and joysticks.
A Full Speed (USB 1.1, USB 2.0)
rate of 12 Mbit/s (1.5 MB/s). Most USB Hubs support Full
Speed.
A Hi-Speed (USB 2.0) rate of 480 Mbit/s (60 MB/s).
A Super-Speed (USB 3.0) rate of 4.8 Gbit/s (600
MB/s).
The USB 3.0 specification will be released by Intel and its
partners in mid 2008 according to early reports from CNET news.
According to Intel, bus speeds will be 10 times faster than USB 2.0 due
to the inclusion of a fiber optic link that works with traditional
copper connectors. Products using the 3.0 specification are likely to
arrive in 2009 or 2010.
