Choosing the storage
If using a product from the Matrox MXO2 family, we recommend that you choose a storage unit that is more than adequate for editing multiple layers of SD or compressed HD video.
When deciding on storage, there are two main factors to consider - the throughput (data rate) the storage subsystem can sustain and the overall storage capacity.
To evaluate your needs, you must first take into account the data rate for the format that you'll be editing. The table below provides approximate data rates for a variety of formats and resolutions. Once you've chosen a storage subsystem that meets your throughput needs, you must determine how much storage your workflow requires. The more storage you have, the more hours of footage you can maintain online for instant access.
