I have smartd running. A short self test is done every day, and a long test
once per week.

Didn't you get errors in yslog then?
I also thought about swapping the system drive - I have a larger backup
drive, with nearly identical logical volumes on it, where I make backups
with rdiffbackup. So even the content is identical, except for an additional
rdiff-backup directory containing the increments. So all I have to do is to
echange the two volume group names, reboot, and the system will run from the
other drive. But I very much doubt this will help, transfer speed looks okay
to me, around 100 MB/s with dd.
