Choosing the storage for a Matrox Axio LE system (for Adobe CS4)

When deciding on storage, there are two main factors to consider - the throughput the storage subsystem can sustain and the overall storage capacity.

To evaluate your needs, you must first take into account the data rate of the formats you will be editing. The table below provides the approximate data rate for a variety of formats supported on some Matrox editing platforms. Multiply the data rate per stream by the number of realtime video layers to approximate the overall demand on the storage. For example, three layers of DV require a minimum throughput of 75 megabits per second (Mbits/sec) plus some additional room for overhead.

  Data rate per stream Hours of footage per terabyte
(Mbits/sec) (MBytes/sec)
8-bit Uncompressed HD9601202
8-bit Uncompressed SD1602013
DVCPRO HD10012.522
MPEG-2 I-frame HD10012.522

Once you have chosen a storage subsystem that meets your throughput needs, you must decide how much storage your workflow requires. The more storage you have, the more hours of footage you can maintain online for instant access. The table above provides an approximation of the number of hours of video you can store on one terabyte in the various formats.
