More Codec performance test
60 different codecs and compression settings on 3 different single drive systems.
Playback is on 1 layer only. Results do not scale to multiple layers
NOTE: System disc is NOT the drive disc.
Tested
Single Raptor 74GB
Single 10k SCSI Atlas iV
Single 15k SCSI
Results:
Different drive Systems are pretty similiar.
10k drive is not slower than 15k drive.
Raptor is slower at uncompressed data - but pretty similiar with compressed codecs. ( Blackmagic codecs are uncompressed )
Single layer 25fps playback of 720p footage is possible with:
photojpeg 50% & 75% and mjpegA 50% & 75%
Single layer 25 fps playback of 1080p footage is possible with
photojpeg 50% and mjpeg 50% ( just )
and marginally at photojpeg 75% and mjpegA 75% ( just )

4 layer playback tests now includes dual raptor
60 different codecs tested playing back 4 layers of the same type of content
tested on internal drive
internal raptor 74GB
scsi 15000rpm Maxtor Atlas 74GB
scsi 10000rpm Maxtor Atlas iV 140GB
dual raptor - firmtek card
Results
Internal drive is very very bad.( and these figures are just averages - not deviations, the internal drive has poor consistency ).
Raptor, and scsi 10k and scsi 15k have close performance.
scsi 10k is slightly faster with some codecs.
Only dv-ntsc will give close to 30fps performance on all 4 layers.
DV-NTSC is slightly faster than DV-PAL- the difference is important

Single and Dual raptor side by side
Single and dual raptors same files.
4th layer complete time
dual raptors have slight edge with dv codecs.
Not much in it.
