Q: “How does Glyph’s QuietMetal work?”
A: Most of the noise in a hard drive system comes from two sources: the hard drive itself, and the fans used to circulate air through the enclosure. Noise is vibration, and it is the vibration of the hard drives and fans that is so objectionable in an audio recording studio.
So Glyph studied the situation, and determined how to stop some of the noise at its source — block the vibration of the hard drive and fan from getting to the chassis, where it could make its way into the studio. The place to do this was in the mounting hardware that holds the drives and fans within the chassis. They took advantage of advanced composite metals technology, and incorporated a tri-laminate — two layers of metal skin, separated (and bonded) by a viscoelastic polymer core — into their systems to dampen vibration and control noise. The tri-laminate metal actually absorbs vibration before it can get to the unit chassis.
They use QuietMetal for the internal drive frames and rear fan panels. The combination of viscoelastic damping and secure fastenings, along with their use of the latest in quiet drive mechanisms, virtually eliminates vibrational noise. This translates into a storage solution that is significantly quieter than other external hard drive systems.
