The Flagship of the GT Series.
Whether you’re recording, mixing, editing or capturing, in any production
environment, the GT 308 will reward you with a stress-free storage
experience. With Glyph’s Integrity™ FireWire hot-swap system, you can be
assured that your data integrity and performance will be consistent
wherever you take your work.
GT 308 is specifically designed for high-resolution audio, and
the high-bandwidth requirements of video. Allocating audio files to
multiple drives will allow you to achieve maximum track counts at today’s
high sample rates. With video production, the high-performance 7,200
RPM hard drives deliver the huge capacity and speed necessary for the job.
Plus, the GT 308 is ultra quiet employing sound-dampening metal in its
frame. This composite metal technology absorbs drive vibration and
reduces unwanted noise.
Extending the reach of the GT 308, Glyph has introduced the
GT 051, a single FireWire Hot-Swap Tabletop receiver. It’s
included with the purchase of a GT 308 so you can easily move your work
from one location to another. In any production environment, Glyph offers
options that go way beyond an off-the-shelf storage system.

Freedom to move with the GT 051.
The GT 051 is included with the purchase of the GT 308 and
accepts the same GT Key drives. Imagine being able to record in
the studio, pull the GT Key drive and take it home to mix the
record there.
What sets this system apart from all other “Hot-Swap
FireWire” products is that Glyph uses its proprietary Integrity™
hot-swap interface in the GT Series. When a GT Key is removed
from the bay, the disconnect happens at a FireWire level. FireWire
was designed to allow the removal and insertion of devices,
whereas ATA was not. Glyph’s Integrity™ FireWire hot-swap
interface provides greater reliability than existing hybrid ATA-to-
FireWire products.
Focused on keeping your studio quiet, GT Key and GT
Series enclosures incorporate sound-dampening metal in their
inner-frames. This composite metal technology absorbs drive
vibration and reduces unwanted noise.
