Difference in Playback Performance between Catalyst and Quicktime

[SourceChild]

...i noticed a significant performance loss during playback AIC Codec Files. I´m 100% shure that the raid settings were fine...

Unless I'm mistaken, you're not using a RAID controller?

If you are not using a RAID controller then the processing resources of the computer are used to control the RAID. Once you do this, the performance bottleneck becomes the processor. A RAID card independently processes the RAID leaving the processor and GPU free to render the output.

no. not true. this is a data transfer problem not cpu.

if one ssd can do 80MB/s 2 ssd should do close to 160MB/s enough to do uncompressed hi-def
in this case using raid should double data throughput rate-
this would be a reason to use raided ssd. and it should work.
