Answers | 1. | Rotation rates, latencies, buffer sizes, and connection interfaces. | | 2. | RAIDs are disk arrays used to improve performance and provide redundancy. | | 3. | RAID levels 0, 3, and 5 are good for video, and Apple's Xserve RAID is optimized for RAID 5. | | 4. | Direct-access storage, network attached storage, and storage area networks. | | 5. | SANs allow either one, depending on the SAN architecture. | | 6. | The number of simultaneous real-time streams you need to record or play, and the bit rates of those streams. | | 7. | The amount of footage to be captured, as well as render files, intermediate or temporary rendered timelines, graphics, and audio files. |
