Understanding
Disk Storage
Methods
The KONA LH card, an Apple Power Mac, and Final Cut Pro, together offer an
unprecedented level of features and performance for all Video/Audio production
applications. However, to ensure performance and quality, the disk storage system
used with the Apple Power Mac must be able to meet the demands of storing
realtime uncompressed media. At the very minimum, the disk storage system must
be able to provide and maintain a consistent 50 MB/s transfer rate from the Power
Mac to disk (read/write). There are a variety of system configurations and
peripherals that can provide this level of performance. Possible system
configurations are listed following:
Disk Storage Solutions—G5 With Xserve RAID
Storage Method
Features/Limitations
Cost
Xserve RAID
Features up to 14 ATA/100
drive channels, dual
independent RAID controllers,
and a dual 2Gb Fibre Channel
host interface. Xserve provides
up to 5.6TB of storage with
throughput of up to 400
megabytes per second.
Expensive, although
the cost per
gigabyte is excellent
when large storage
is needed
External ATA/IDE or SCSI
RAID
Scalable. Performance almost
as good as Xserve, although it
can be more complex to set up
and maintain. Many vendors
offer solutions (too many to list
here; check with your Apple
dealer for SCSI Storage
solutions for details). Although
the connection to the external
RAID chassis is SCSI, the
drives themselves may be
SCSI or ATA. A pure SCSI
array will offer higher
performance at a higher cost.
Moderately
Expensive
