Ho hum. It's a bit more complicated than that, and simpler ;-) For a simple minded performance comparison, check out http://www.geli.com/data/disk.perf.html What I take from that is the drivers have essentially the same performance. Both are superb, and drive these disks about as fast as they can go. *However*, the 2940 driver supports a number of drives the NCR driver does not. As I write this, I'm building my first world on a $965 Grand Prix 4.3G, which I don't think is possible with my old friend the ncr driver. The NCR driver works terrific on Q Atlas drives though. The NCR driver in Linux has suffered through a lot of ups and downs. Not so the FreeBSD driver, it has been cranking along at full disk speeds for about 13 months now. > >considering it's about 2 to 3 times the cost..
