Common
Video Data Rates
One
of the common problems we have seen on occasion is that when designing a storage
solution not enough thought was given to video data rate requirements. The
digital world is
still a new area to many who have just come from an analog world. The
traditional storage
people think in
IOPS not data rates. Knowing performance
requirements to support
different video formats is part of the job. We hope the following
chart will help clarify and
identify the various video data rate requirements we see most often that need to
be considered
when designing a related solution.
The
following table provides data rates in MB/sec for various types of video
streams.
