Hi Dietmar,
I know someone else was on this thread, but I will add my comments as well.
As for pagefile, Write cycles, ETC, that is one of the primary uses of the
EWF... use a RAM based overlay, and then the OS will load from CF directly
into RAM. all Paging, writebacks, ETC will happen in the RAM. This will keep
your CF viable for a long time. (like as long as a hard drive) Just make
sure your BIOS supports CF boot, and also the CF Card has to be reset as a
"fixed disk:" and not removable. (tool to do this available from CF MFR)
Another nice feature that will be in SP2 is the Hibernate once, resume
Many... This allows you to set a designated wake point to boot the PC from
(allowing faster boot times) Again, Your CAN controller will most likely
still be an issue, but with this feature, you might want to look around a
little further for a card that supports it.
CF is not noticibly faster than a HDD but in an automotive environment it's
leaps and bounds more reliable.
Hope this helps a little.
