Has anyone bought a rewritable optical disk from HP? Are
you happy with it?

We bought one a few weeks ago and use it for backup, among other
things. According to HP figures on backup rates, the backup rate
to an optical disk is about 900 MBytes per hour. Our experience
is that it takes roughly 4 hours to back up a 300 MByte disk,
i.e. 75 MBytes per hour. We have asked HP about this several times,
but nobody seemed to know anything. We use cpio to do backups, exactly
as recommended in the manual. Are we doing anything wrong? Does
anyone else have similar or different experiences?
