AcomData 2163 Drive Enclosure
Features Explored
Hi-Speed USB 2.0
USB (Universal Serial Bus) is an interface technology for the
serial transmission of digital data. The original standard
(USB 1.x) had an interface transfer rate of up to 12 Mbps.
USB 2.0 has a maximum interface transfer rate of 480 Mbps
(60 Megabytes/s) –– that’s up to 40 times faster than USB 1.
Interface transfer rates up to 480 Mbps
480 Mbps is equivalent to 60 Megabytes per second. 480
Mbps is the maximum 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
usually 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 without a dedicated electrical connection.

Plug & Play
You do not need to assign ID numbers, or connect terminators. On most operating system you do not need to install
drivers. Your AcomData 2163 Drive Enclosure comes with
USB 2.0 driver software for Windows 98SE users.
Hot-Pluggable
Devices can be added/removed while the computer is running. Always dismount a hard drive before turning if off/disconnecting it.
FireWire 400
(FireWire-equipped Drives only)
FireWire is a serial data input/output technology developed
by Apple Computer and Texas Instruments. The first FireWire
standard was approved by the Institute of Electrical and
Electronic Engineers (IEEE) in 1995.
400 Mbps Interface Transfer Rate
FireWire 400 can transmit data at up to 400 Mbps (50 MB/s).
FireWire supports both isochronous and asynchronous data
transfers. Isochronous mode provides guaranteed transmission of data at defined intervals; it’s used when delayed or
out-of-order data frames are unacceptable, such as for
capturing digital video. In asynchronous mode the intervals between transmissions can vary and data can be resent if
missed. Asynchronous mode is used for routine data transfers.
Supports up to 63 devices
FireWire devices can be linked in a daisy-chain, where the
devices are connected to each other in series. A hub is only
required when a very large number of devices will share
– 13 –
the same FireWire bus. With the use of FireWire hubs, up to
63 devices can be linked on a single FireWire bus. FireWireequipped 2163 Enclosures come with two FireWire ports:
one port is for connecting the device to your computer; the
other can be used for daisy-chaining other FireWire devices.
Peer-to-peer, host-independent architecture
Data transmissions between FireWire devices on the same
bus can take place without the need for input from the host
computer. This independence from the host is one of the
reasons FireWire devices are, on average, faster than USB 2.0
devices in routine day-to-day use, even though the rated
maximum data transfer is lower than that for USB 2.0.
Cable length up to 4.5 m
Standard FireWire 400 cables use 6-pin connectors at both
ends. Cables with 4-pin connectors are also available for
connecting FireWire devices to laptop/notebook computers
and other devices that have 4-pin ports.
On-bus electrical power up to 45 watts
FireWire can supply up to 45 W of power, making it possible
to use many low-power-consumption devices without a
dedicated electrical connection. When a device is powered
via FireWire, power is delivered only when actually needed.
Plug & Play
You do not need to install drivers, assign unique ID numbers,
or connect terminators.
Hot Pluggable
FireWire devices can be connected to or disconnected from
the computer while the computer is running. Always dismount a hard drive before turning off and disconnecting it.
– 14 –
Hot-Pluggable
You can connect or disconnect FireWire devices while your
computer is running. This makes portability much easier
and saves you the time and hassle of shutting down and
restarting your comp
off while your computer is running. Let’s say you use your
Drive solely for data backups–so the Drive only needs to run
a few minutes every day–but your computer is on all day. If
the Drive was not hot-pluggable, you would either have to
shut down your computer every time you wanted to turn
the Drive on or off, or you would have to leave the Drive
running all day unnecessarily.

Fanless Design
All hard drives generate some heat as a result of normal
operation, which is why hard drives often have big, noisy
fans. The 2163 was engineered to be more efficient and to
generate less heat, such that it does not need a fan, allowing us to make the drive as compact and lightweight––and
quiet––as possible.
