[Soekris] List of Known-Good CF Cards?

[Tuc at T-B-O-H.NET]

Hi,

	My application is :

		MRTG collector/grapher
		Syslog for about 5 other pieces of equipment
		Store/Forward for Webcam alarms

	So it isn't an OS issue, its an issue of needing to do alot of
read/writes. I was hoping because its a very hostile environment
(Its a closet with 2 water heaters and a water treatment system, sometimes
getting up in the low 100's, 700-750 feet away from the the Atlantic Ocean 
depending on tides, unmanned site) that a CF card would be a much better
option than a hard drive. Now, I'm not so sure! This card *MAY* be ok. The
system had one other mysterious lock up recently from which only power would
get it to reboot. It might have done it again, I don't know and won't know
until I drive the 11 hours + rent the jeep, or hire a remote hands company
to do it (They want $250 an hour, site is 1 hour away from them). Expect
me to re-open my thread about the system freeze soon. :)

	Yea, its been expensive (Between Soekris, CF, and USB pendrive they
start to get up there in price) but I was hoping it would be a great solution.
It still might be, I might just need to tweak the configuration a bit.

			Thanks, Tuc
