They seem to be.

: Next check the speed of the disks with something like iozone.

IOZONE tells me:

JAZ:	1.5MB/s write, 5.2MB/s read
Fireball: 1.4MB/s write, 2.7MB/s read

Disks are both 4500 rpm.  The JAZ is 12ms seek and the Fireball is
10.5ms seek time.

These disks could easily be much faster :-)  However, async, noatime
mounting seems to be about the best thing I can do for the build.  I
have about a half dozen builds done now, and want to do one or two
more.  I'll post the summary when I finish.
