A few days ago, I suddenly realized that under heavy file transfer, my system was rather sluggish (I don't do much transferring of large files, so I didn't really notice before). The obvious answer of course would be that my hard drives are running in PIO.
The problem is, my RAID 0 is running off an old Iwill ATA66 card (Highpoint chip). Now, in the RAID BIOS there's a DMA setting. This is on, of course (if I left my drives in PIO, I'd kick my own ass :tongue: ). The thing is, everything in a PCI slot has to go through the CPU to get to the RAM (i.e. PIO). So is it even possible for a PCI RAID card to run in DMA? I couldn't find any setting in Windows for this, only on the motherboard's IDE controllers.
This year I'll probably grab a couple of 60-80GB 120GXPs (or if something better shows up before then). At that point I'll go back to the onboard RAID on my TH7II-RAID (I know now that it was a driver conflict, and I know which driver version I need to fix it). But until then, I'd like to get my hard drives set up properly.
Can anyone shed any light on this? Is it possible for a PCI RAID card to run in DMA? If so, how would I set this up?
