As far as I know (still learning myself) application data is stored in the Ogo
main memory bt default ( no matter where the apps reside). The data that is
copied using the transfer app, is for backup purposes. This allows you to restore
your application data from the sram card, in case of total power failure, or data
corruption.
I'm not exactly sure, how to move data to the Sram card. (Other please help here)

Sram batteries have a typical life of about 6mo to 2yr, depending on type and
RAM size. Most Sram card specs state half the battery life for an 2M vs 1M
sram card. (same battery, twice as many memory chips)

Again, not being an expert, nor an owner of a sram card, I'll explain to the best
of my knowlege. The sram batteries should not be affected significantly by usage.
(if they are supposed to last 1yr, they should last that long with heavy or mild
usage) The standby current on Sram (and ATA flash) cards is typically 1ma. This
amount of current draw should have very little impact on Ogo batteries. But (there
alway is a but) the current draw during read or write operations can be 40-120ma.
(this is significant) So what does all of this mean? If you are concerned with
battery life, keep the application data in the Ogo memory. Also keep very frequently
used applications in Ogo memory. This should help keep the battery drain down.
The application data is the most important, because it is accessed more frequently
than the application code.
I personally have an 4M ATA Flash card, and so far have noticed little impact
on the Ogo batteries, since I don't access the application on the card very much.
These are good questions. I am currently working on a list of question, to ask
in a Ogo Ram survey. I should have an preliminary questionare for review, in a
few days. Hopefully this will help future users contemplating add on Ram cards.
