Compact Flash dies after 10,000 read/write cycles?
True, didnít know this myself but I confirmed it with and FAE. I am looking for an explanation of why this happens
Preface: I have done a lot of work with embedded systems with the system on a CF module.
This is true, but not exactly correct. What actually happens is that individual "cells" of the memory die after SOMEWHERE around 10,000 write cycles. NOT read. You can read from a CF an infinite number of times. Writing is where you start ticking the death clock. Keep in mind though, just like bad blocks on a disk, the disk controller will cordon off those blocks and make sure they can't be used. If you have a system where your OS is on flash, try to make it read only. I doubt this is possible with Windows, but maybe. With Linux, its possible and should be done. Put temporary stuff that needs to be written like logs in a RAM disk.
SanDisk Extreme CF III is supposed to last 20,000 write cycles.
Industrial version 200,000
Edit: Check out nLited systems w/EWF and Minlogon (as said above) and Check out uDOC solid state storage.

The 3.5" Drives use about 15 watts more and places more load on the DC to DC converter. We used the 2.5" drives allowing the system to run cooler. As long as your using a good power supply (Not the 60w morex) you can use the 3.5" you might want to add some extra fans.
