Storage Requirements
SD|Greed is primarily an uncompressed capture and playback card providing an
unprecedented level of quality on the Windows, Linux and Apple Mac OS systems.
Bluefish444 recommends that your storage system be able to provide and sustain a
data rate up to 45 MB per sec for single stream applications and at least up to 90 MB
for dual stream and above for multiple stream solutions.
Certain applications may require specific storage requirements and can be broken
down into the following category types
Single Stream Applications that capture and play back one video clip or frame
at a time.
Single Stream Sequential Applications that capture and playback sequential file formats
such as DPX, Cineon, TGA, TIFF
Multiple Stream Applications that playback multiple video clips simultaneously.
For real time effects between two or more clips such as
dissolves, titling, masking etc
Multiple Stream Sequential Applications that playback multiple streams of sequential file
formats simultaneously such as DPX, Cineon, TGA, TIFF,
MOV
Note, the following examples are based on Standard Definition resolutions and are
provided as a simple guide.
The ability of the storage solution and the RAID type used, will determine how many
streams of uncompressed SD streams your application will be able to playback in
real time.
NOTE “SCSI to SATA” refers to a JBOD SCSI interface with SATA hard drives in
a RAID configuration. SCSI to SCSI is the same but with SCSI hard drives
