Because when it says ATA/66, that means 66MB/sec maximum throughput per channel. Since there is only one IBM drive per channel, you're never going to hit 66MB/sec. The only real speed limitation in this case is the speed of the PCI bus - 133MB/sec.

I think their RAID 1 would be sufficient for me, though it halfs my disk space, if I'm not mistaken. Maybe I'll have to get 8 drives then :) Gabe -- -------------------------------------------------------------------------------- Gabe Turner | X-President, UNIX Systems Administrator, | Assoc. for Computing Machinery U of M Supercomputing Institute for | Univerisity of Minnesota Digital Simulation and Advanced Computation | dopp at acm.cs.umn.edu "You've really lost it this time....you've lost your mind!" - Ren finds out about Stimpy's Stinky Butt Fantasy in "Son Of Stimpy" -------------------------------------------------------------------------------- --------------------------------------------------------------------- To unsubscribe, e-mail: tclug-list-unsubscribe at mn-linux.org For additional commands, e-mail: tclug-list-help at mn-linux.org -------------- next part -------------- --------------------------------------------------------------------- To unsubscribe, e-mail: tclug-list-unsubscribe at mn-linux.org For additional commands, e-mail: tclug-list-help at mn-linux.org
