Storage memory faster than main memory

I've been testing a bench marking application (SKTools) on the Sprint Mogul:

and I'm getting the following read write times for my storage memory and main memory:

Main Storage (write) - 1198.50 KB/Sec
Main Storage (read) - 2617.81 KB/Sec
Storage Card (write) - 1318.74 KB/Sec
Storage Card (read) - 6077.15 KB/Sec

I was actually pretty surprised to see that the storage read time is that much faster! Currently all of my applications are running from main memory, and I'm contemplating doing a hard reset and putting them all on the storage card. It seems like we would see some performance gains doing this, but I'm not 100% sure. I think there may be other factors that may come into play. Anyone have any information / experience with this? The storage card I'm using is a SanDisk 4GB card I purchased from ebay.

You should try using a program like memaid to set all of your stuff to run from the storage card and see how it performs. That would also free up some RAM for you. It has options to run .dll files from storage card instead of RAM and it also can move the cache and other stuff as well.

Keep in mind that the system's cache ram might be kicking in for storage memory.

i noticed a while back that i see these sort of results when i have set fatfs cachesize=4096

with cachesize=0, sktools shows very close results for storage and main memory.
