Hard Disk Storage OptionsHard Disk Storage Options

Generally, like health, wealth and happiness, you can never have too much video storage on your edit system. That said, you can always add more disks later when you need them, and with the general downward trend in disk prices (measured in $$$/GB) there's no point in buying more than you need, until you actually need it.

So how much disk space do you need?

The first consideration is the quality level (or compression ratio) that you'll be working at. The chart below lists approximately how much Standard Definition video you can store on a 36GB SCSI disk at various quality levels. It takes into account that an 36GB disk is often closer to 34,000MB, and that you can't expect to reliably fill the disk with video beyond about 90% capacity, so the predictions are hopefully more realistic than optimistic.
