Hi-Speed USB 2.0
(USB 2.0-equipped Drives only)
USB (Universal Serial Bus) is an interface technology for the
serial transmission of digital data. The original standard
(USB 1) could transmit data at speeds of up to 12 Mbps.
USB 2.0 has a maximum throughput of 480 Mbps (60
Megabytes/s) –– that's up to 40 times faster than USB 1. USB
is a host-dependent technology, meaning USB devices need
the computer to facilitate and manage communications
between devices.
Data transfer rates up to 480 Mbps
480 Mbps is equivalent to 60 Megabytes per second. Put
another way, it is possible to transfer a full gigabyte of data
in just under 18 seconds. However, 480 Mbps is the maxi-
mum speed; data transfer rates will vary depending on a
number of factors, including available CPU resources.
Supports up to 127 devices
Connecting more than one or two USB devices to a computer
typically requires the use of one or more USB-equipped
hubs; a hub can typically accommodate several USB devices.
Master-slave architecture
The computer (the master) dictates data flow to, from, and
between attached USB devices (the slaves).
Cable length up to 5 m
On-bus power up to 2.5 W
USB can supply up to 2.5 W of electrical power, making it
possible to use many low-power-consumption devices with-
out a dedicated electrical connection.

Plug & Play
You do not need to assign ID numbers, or connect termina-
tors. On most operating system you do not need to install
drivers. Your AcomData E5 Drive comes with USB 2.0 driver
software for Windows 98SE users.
Hot-Pluggable
Devices can be added/removed while the computer is run-
ning. Always dismount a hard drive before turning if off/dis-
connecting it.
Mac & PC Ready
Your AcomData E5 Drive is ready to use on either a Mac or
a PC right out of the box––no formatting is required. The
Drive was formatted at the factory using the FAT32 file sys-
tem, which makes the Drive compatible with all supported
operating systems. That said, you may want to consider
re-formatting the Drive using one of the other file systems
that may be available with your operating system. For more
information and formatting instructions, see "Re-Formatting
the Drive. "
Hot-Pluggable
You can connect or disconnect the AcomData Drive while
your computer is running. This makes portability much
easier and saves you the time and hassle of shutting down
and restarting your computer. You can also turn the Drive
on and off while your computer is running. Let's say you use
your AcomData Drive solely for data backups––so the Drive
only needs to run a few minutes every day––but your com-
puter is on all day. If the Drive was not hot-pluggable, you
