Yes SATA raids can give great single stream results, but try multiple streams.
On my 4 disk riad using diamond max (I think) I know they are the 16 meg buffer 300 gig drives with a rocketraid 8 port card I am well over 200 megs/ sec.
I am however not able to do 3 streams uncompressed 8 bit, or 8 stream of DV (not testsed with multicam)
I can get 7 or 8 streams of DV from 1 internal SATA drive (G5 2.7, 4 Gigs ram, Kona 2)
Using FCP multicam, the sata raid 0 could nto reilably play back 8 streams of DV using multicam for a coencert film I am doing. However, my Huge systems dualmax dusl scsi ultra 160 (even with a Ul3d @33mhz is able to play them back with far fewer problems. (and no the 33mhz card was not in the systems the same time as the rocketraid was.
Anyone else found multiple streams to suffer on sata raids?
Please post what you are getting? BTW my test for multi stream (before FCP5’s multicam) is simply scaling down clips and placing next to each other with no other filters, ect in RT extreme aaf full quality with “warn if dropped frames” on
