Re: IOS -- Why recommended Flash is Much more than Image Size
Generally memory sizes are incremental ie 16,32,64,128 etc... So of course you have to have the available amount of memory to be able to store the IOS on it. Many routers now come with the SDM GUI that takes up 6-8Mb on flash memory, and I think Cisco does take things like that into consideration.
On your second image with the 512Mb recommended amount of flash I think is a typo. I see no reason why 512Mb is required for a 78Mb file. You could hold several IOS files with that amount of flash (which is nice) but not required.
I believe that the vlan.dat and the startup-config are still housed in NVRAM. Which is a completely different file system than flash.
