Software For Striping. AJA KONA LH/LHe

RAID 3, or distributed across an array of drives, as in RAID 5. Parity provides much greater storage efficiency than mirroring—up to 85 percent for a set of seven drives.

Software For Striping

AJA recommends the Disk Utility software provided by Apple with OS X for creating and striping RAIDs, including 3rd-party, SCSI, and Xserve RAIDs. It is very easy to use and has been tested to work well. The utility can be found in Macintosh HD/Applications/Utilities, where

“Macintosh HD” is the name of the system drive.

Storage capacity

No matter which storage system you choose, pick one that can scale to meet your needs over time. Ideally, you should be able to increase storage capacity or switch to a RAID level offering increased data protection in the future. Balance current and future storage needs with your budget and choose accordingly.

MB = MegaBytes

GB = GigaBytes for uncompressed formats, PAL and NTSC transfer rates and storage requirements are about the same because PAL has a lower frame rate, but more lines.
