Gerard,
Here are some new results with ncr53c8xx-2.6i. I ran Bonnie and
Iozone on two Ultra2 drives simultaneously. The results weren't bad.
For Iozone:
1 drive: 13389.05 read / 9621.50 write
2 drives: 11608.85 read / 7092.95 write
Not bad. I will append the complete results.
Unfortunately, I don't have the complete system log, but here's some
pieces of dmesg output you may want to see.
Larry
