Question ID: 704398
I am buying a ProTools MBox 2 for my 1.67GHz Powerbook which has 1 GB
of RAM and a 100GB Hard Drive. I need to purchase an external hard
drive to store my  sessions onto. It was suggested that I purchase a
Glyph external drive, which is specifically built for pro audio. What
I need to know is:  is it really worth paying $350 for a 250GB Glyph
external Firewire drive when I can buy an Iomega USB-Firewire drive
with 250GB for $160 ?  What makes the Glyph drive worth the extra
cash?

Sweetwater Sound is a store (and website) dedicated to music and
audio products for the professional. Their review on the Glyph
makes it clear why they feel that the Glyph is more suitable than
the Iomega, which is, tellingly, bundled with backup software, as
that is what it's designed for.

On the other hand, the Glyph comes with a built-in power supply,
independent of your PC's USB supply. It offers a standard dual 
6-pin powered FireWire 400 interface, two 9-pin FireWire 800 
connectors, a USB 2.0 connector, and one eSATA port.

In addition to being specifically designed to eliminate unwanted
noise in a studio environment, through the use of Glyph's patented
QuietMetal technology, it comes bundled with the Glyph Audio Storage
Toolkit formatting and partitioning software, and includes the Glyph
FireWire bridging technology.

In short, it was specifically designed for audio recording, mixing
and editing of multi-track audio, and to handle high definition 
sample rates:

As to whether you have need of these specific enhancements within
the recording environment you have set up, that is a personal choice.
If your setup is entirely digital, and ambient noise is not a factor
in your studio environment, you might find the Iomega a satisfactory
solution. Here's a review from the UK's Pocket-lint site regarding
its value as a backup device:

I understand that Glyph drives are less noisy but as I operate in an
entirely digital environment I'm not worried, so I'm moving towards
the Iomega models.  The review you provided was from an older Iomega
250GB model. Could you possibly provide reviews for the models I'm
interested in, which are the Iomega Black Series Triple Interface
250GB, and also the Black Series USB/Firewire 250GB (both on Iomega
website)?   I'd like to know whether both of these have an "Oxford 911
FireWire bridge chipset" which is what Digidesign needs for a Firewire
drive to be compatible; also if the seek time is less than 10ms on
both; what makes Firewire 800 preferable over Firewire 400. You may
refer to the following compatibility document if you wish:

Your Request for Clarification poses questions not included
in your original query, and had they been, I probably would
not have attempted an answer...

For what it's worth, here's what I -could- find:

"Could you possibly provide reviews for the models I'm interested
 in, which are the Iomega Black Series Triple Interface 250GB, and
 also the Black Series USB/Firewire 250GB (both on Iomega website)?"

Iomega Black Series Triple Interface 250GB

"Of the approximately 30 hard drives I?ve tested recently, three
 stand out as Macworld Top Products (see the tables in this review).
 The Iomega Black Series Triple Interface drive is our winner in
 desktop hard drives, thanks to its various connection options,
 very quick speed (especially in copying data to the drive) and
 low cost per gigabyte."
http://www.newertech.com/Static/articles/article_macworld_mercfwguide.html


"what makes Firewire 800 preferable over Firewire 400"

The Triple Interface drive offers Firewire 800, 400 or USB 2.0:

"Transfer speeds up to 800Mbits/s with FireWire 800, 400Mbits/s
 with FW 400 and 480Mbits/s with USB 2.0"
http://www.iomega.com/direct/products/detail.jsp?PRODUCT%3C%3Eprd_id=20125171&FOLDER%3C%3Efolder_id=27290767&ASSORTMENT%3C%3East_id=26890319&bmUID=1141813411268

The 250GB USB/Firewire offers only Firewire 400 and USB 2.0:

"Transfer speeds up to 400Mbits/s with FW 400 and 480Mbits/s
 with USB 2.0"
http://www.iomega.com/direct/products/detail.jsp?PRODUCT%3C%3Eprd_id=20125163&FOLDER%3C%3Efolder_id=27290765&ASSORTMENT%3C%3East_id=26890319&bmUID=1141813411269


"...if the seek time is less than 10ms on both"

Access speeds are not mentioned for either, anywhere that
I can find, though they both have spin rates of 7200 rpm.
Transfer rates seem to supercede seek times.


"I'd like to know whether both of these have an "Oxford 911
 FireWire bridge chipset" which is what Digidesign needs for
 a Firewire drive to be compatible"

The lack of results for the following crafted search seems to
preclude the possibility that the Iomega Black drives have this
chipset, thought there is no indication, one way or another on
the Iomega site:

"Oxford 911" FireWire chipset "external drive" +"Iomega Black"
://www.google.com/search?q=%22Oxford+911%22+FireWire+chipset+%22external+drive%22+%2B%22Iomega+Black%22


Drive brands that show up in relation to the Oxford 911 chipset:

Micronet Platinum 250GB USB 2.0 / Firewire Hard Drive

Hiro Firewire Aluminum Drive Enclosure with Oxford 911

Rosewill RX30-U2FA Firewire-400 drive with the Oxford 911 chipset.

OWC Elite Firewire Case

Thanks for clarifying the differences between various hard drives. I
think I understand what to do now.
