Have you ever worn one out?

I've tried. Running an Apacer PhotoSteno II 512MB card as the hard
drive in a Net4801 with an OpenBSD installation done as it would be on
hard disk. I mounted the partitions noatime and softdep, turned on the
highest verbosity for logging for the spamd tarpitting greylisting
daemon.

I then let it thrash for a year with zero errors and, believe me when I
say that verbose logging thrashes the drive, with 8 levels of archived
rotated logs there are lots and lots of writes. Of course deletes cause
lots of writes too.

The same CF is still running with two more complete re-installs in its
history since that period but I moved the spamd filtering to the
mailserver when I used a hosting service to bridge a gap between two
ADSL connections so it's not thrashing quite as much since then.

Still zero errors. It's only a fast consumer grade CF not one of the
industrial units. About to be replaced with an even faster PS-III from
Apacer for a quick changeover upgrade of the OS but I won't toss it
out. We also have a stack of clients with CF cards up to two years old
in firewall service. In one case a multi-national tourist outfit. Guess
what their logging rate is?

None has ever given us grief.

I think that somebody needs to update all the old time stuff about CF
wearing out in no time.

Meantime I save fiddling with custom kernels, using ramdisk etc etc.
