why 4 rom slots?

[lowvolt]

Why are there 4 ROM slots when using safe strap on RAZR m? I don't seem to have enough storage on the internal memory to create more than one.

There are 4 so you have the ability to create and switch ROMs really quickly. The average user should only need 1gig per slot though so i'm not sure why you don't have enough space. How much space is left?

On the internal it shows it has almost 5 GB with .92 GB left. I also have a 8 GB external with 1.19GB left. If i got more external storage can i put everything from internal on external to free up internal storage? When creating slots do they have to be on internal? Can I create back ups of current ROM and place on external?
