My problem is that the 2 OS drives are 160GB, whereas my attempt at a poor man's raid5 are 4x250GB. One thing I noticed. copying 240G worth of crap from a 250GB drive, across the motherboard's IDE interface, into the megaraid i4 raid0 (160GB on channel 0, 160GB on channel 1) took 2 hours. Copying from the above raid0 onto the 4x250GB raid5 (2 drives on channels 2 and 3) took 13+ hours. Does raid5 really use up that much cpu? I couldn't have saturated the PCI bus or the individual ide channels, could I? -Tai
