I've been using the same CF card for a few years, and have never
had any problem. The same is not true for three different hard
drives.

Of course, the hard drives are now all "old" drives, and deserve
to be able to fail in peace, but I have no reason to worry about
the reliability of CF card(s) (which are wear-leveled) and trivially
backed-up and restored to new cards, if necessary.

On an 8MHz accelerated //e, the speed of the CFFA never seems to
be a bottleneck at all.

I would also be interested in speed comparisons for typical file
operations, but, subjectively, it's plenty fast enough not to be
an issue.
