I found the problem: disk cache not enabled on one of the RAID
controllers. Now I have:

On a non RAID partition:
# time dd if=/dev/zero of=/var/crash/z bs=1024k count=100
    0.98s real     0.00s user     0.34s system

On a RAID partition:
# time dd if=/dev/zero of=/home5/z bs=1024k count=100     
    2.53s real     0.00s user     0.36s system


Are the numbers reasonable?
