Bus Power
Bus-powered with FireWire 800 or USB for optimum compatibility, it also includes an eSATA port for the fastest speed possible.
eSATA is not a bus-powered interface, however, you can use the eSATA connection for data transfer while simultaneously using the
FireWire 800 connection to power the drive. This allows the fastest connection possible AND bus power from FireWire. An external
power supply is available for purchase as an accessory if bus power is not available.
Studio mini can be run successfully using FireWire and/or USB bus power supplied by many notebook computers, however Glyph
cannot guarantee compatibility with all notebooks due to differing bus power specs.
Front panel LED
The Studio mini front panel has a bi-color LED. The LED will display solid blue when power is on. The LED will flash blue when
there is disk activity. The LED will flash or display a solid red color when error conditions exits with the drive or enclosure. Any
error that results in the system state “Halted” generates a solid red LED on the front panel of the drive. All other errors result in the
blinking red LED.
About eSATA
• eSATA is an external interface technology that grew from the internal SATA I interface.
• The Studio mini eSATA port supports speeds up to 6 Gb/sec (600 MB/sec), much faster than FireWire 400 or FireWire 800.
• Shielded eSATA cables up to 2 meters in length are available.
• eSATA cables are different than SATA I cables, they are shielded and cannot be used with internal SATA I connectors.
• eSATA uses a “point-to-point” connection, therefore each eSATA drive needs to be connected to its own eSATA port.
• Most computers do not have built-in eSATA, so you’ll need a PCI card to connect your drive with eSATA.
About FireWire
FireWire is an implementation of the IEEE 1394 serial bus standard. It not only supports automatic configuration (“plug and play”)
and hot-swapping of devices, it’s fast, and best of all it’s reliable for audio/video as well as for computer peripherals. FireWire
supports peripherals in a tree-like structure, and it allows peer-to-peer device communication—e.g. between a scanner and a
printer—to take place, without using system memory or the CPU. With FireWire you can hook up to 63 devices to the same bus,
with cable lengths of up to 4.5 meters (14 feet) including internal cabling, allowed between devices. Its cable is convenient and
can also carry power. This allows low-consumption devices to operate without a separate power cord, by using power supplied by
other devices on the bus.
About FireWire 800
• FireWire 800 supports speeds up to 800 Mb/sec, twice as fast as FireWire 400.
• If your computer does not have built-in FireWire 800, you’ll need a PCI card to achieve a true FireWire 800 connection.
• Most 800 ports are Bi-Lingual, which means they speak both FireWire 400 and FireWire 800.
• If you connect a 400 device to an 800 device, you will be running at 400 speed maximum.
• FireWire is forward-compatible and back-compatible.
• Beta cables are used to connect 800 devices to 800 devices.
• Bi-Lingual cables are available to connect 400 devices to 800 devices.
• Bi-Lingual cables have a 9-pin Bi-Lingual connector at one end and a 4-pin or 6-pin FireWire 400 connector at the other end
