I'm currently getting !41 MB/s from /dev/zero writing to the filesystem,
and ~50 MB/s from the filesystem to /dev/null.  It's an array of 4 IDE
7200RPM drives running at ATA100, so theoretically, I should be able to get
up to 100 MB/sec per drive, correct?  I'm also wondering if the speed should
be able to go over the maximum drive speed since I technically am writing to
more then one drive.  I'll probably be benchmarking it later on my desktop
by importing and exporting (3800X2, 1 GB RAM), but more then 64 bit will be
making a difference there.


not sure about slow down of going to 32bit but i do doubt you are going to
get 100MB/s, i have a 250GB Sata drives and they get about 65MB/s max. Also
remember that ata slave and master share bandwidth so if you have both on
one controller the bandwidth is cut in half, so expect a max of 50MB/s per
drive max.
