HI-SPEED USB 2.0
USB 2.0 Key connection
Since its release in 2000, USB 2.0 has provided the necessary bandwidth to support electronic and computer
peripheral devices, including hard drives, CD/DVD drives, and digital cameras. Data transfer rates can reach up
to 480 Megabits per second (Mb/s).
The USB 2.0 standard requires native USB 2.0 cables and connectors to achieve Hi-Speed transfer rates. Please
note that USB 2.0 cables and connectors are compatible with the USB 1.1 interface, an older and much slower
iteration of the USB serial standard. USB 1.1 was released in 1998 with transfer rates of up to 12 Mb/s.
Plugging a USB 2.0 Device into USB 3.0 or USB 1.1/Legacy Interfaces
Your LaCie USB 2.0 Key is meant for use with a USB 2.0 interface. However, USB 2.0 keys are also compatible
with other USB serial interfaces:
USB 3.0 Port
. You may plug a USB 2.0 device into a USB 3.0 port to access or copy data. However, file transfer
rates will not exceed USB 2.0 speeds.
USB 1.1 or Legacy Port
. You may plug a USB 2.0 device into a USB 1.1 or Legacy port to access or copy data.
However, file transfer rates are limited to USB 1.1 or Legacy speeds.
SUPERSPEED USB 3.0
USB 3.0 Key connection
SuperSpeed USB 3.0 is the latest version of the USB standard, providing higher bandwidth and greater power
economy.
Transfer rates for USB 3.0 can attain up to 5 Gigabits per second (Gb/s). Due to such high potential for reading
and writing data, USB 3.0 is theoretically up to 10 times faster than its predecessor, USB 2.0. To allow for easier
adaption to new technology, USB 3.0 portable key drives and USB 3.0 cables are built for backwards
compatibility. It is possible to connect them to USB 2.0 ports on a computer. Please note that transfer rates will
always adhere to the speed of the computer's USB connection type.
