I did not say they will never wear out. People treat them as though that was true. I have
seen some data that says millions of rewrites are possible.

Well I haven't used the brand you see there but it is a Compact Flash device. Your wife's
camera obviously uses a different device. Broadly speaking the tech is much the same but
cameras use devices more compact than Compact Flash sometimes. If that pun is visible to
your reader (grin). There are types like SD (my camera has one) and others are one-brand
types. You need Compact Flash for Soekris. I use Apacer Photo-Steno II with success.

I pay about $AUD80 for the 100x speed Apacers that I use and this week that is about
$US56, so you are getting off lightly but it may not be as fast. Probably fast enough.

I have one handling a 2 megabit link plus a 512 k backup and it does it easily.
