These amounts will be useful when trying to purchase storage for your SD/HD Video Editing system. Most systems do capture compressed, but now more commonly systems will capture at uncompressed data rates. It is important to remember that with uncompressed data, you need more hard drives stripped together in RAID configuration to handle the speeds. Such manufacturers that provide mutiple disc arrays are Huge Systems (Ciprico), Medea, Stardom, and G-Technology. You can connect them using SCSI, FibreChannel, and Firewire 800.
