A while ago, there were HD wars with long discussions (both here and in the mag-rags) about the pros/cons of DMA HD's in an animation/video processing environment. I got the impression that for those application environments, the non-DMA (or partial DMA a la GVP) were preferable to the DMA implementation due to possible contention for chip ram access. The reviews and literature on the A3000 mention a "SCSI DMA hard drive controller chip…" What does this mean to the video/animation user? Is it better to upgrade to the A2630, GVP SCSI HD ctlr in a 2000 or go for the A3000 or is it a "max nix" situation in that area? wmc
