You're right about DMA and the Maxtor drive.- the drive is actually on the primary IDE controller but I just checked and it is operating in PIO mode. "DMA if available" is checked and DEMA is enabled in the BIOS - but PIO shows as the current mode. Maybe I have the jumpers on the drive set incorrectly. To be honest the drive is just sitting there as extra space - the the home of stalled projects that fall outside of the normal work flow - and doesn't see much use. I ran the test on one of the backup drives - a Seagate EIDE 120 gig in a Vantec caddy. (I think there is a Western Digital in the other caddy.) It is on the secondary IDE channel and DMA is working for it. Running the test on it, it comes in on par with the 250 gig SATA - which surprises me since I thought that IDE was inherently slower than SATA. > My motherboard is a 2002 Supermicro design which I commissioned in > early 2004 so it seems like it's still offering reasonable > performance.

Aside from the WD's I'm also using an 80 gig Maxtor USB 2.0 drive and a 40 gig Accomodata for miscellaneous backups. The Maxtor was the first external USB 2.0 drive I bought, I think 3 years ago now. I stumbled into it on the clearance table at an office supply store for only $35. I think that would still be a good deal for an 80 gig external drive even today.
