I made more advanded tutorial howto enable the unused mtd partition as swap. With this method you can freely still use the mass-storage mode. Disclaimer: you can brick your device if you don't have opensh and don't follow instructions carefully.

I'm not going to make comparision if onenand mtd partition is faster than mass storage flash partition. If pages are cached in either flash its going to be a bit slower than ramz. Performance benefit of this is that you have 256MB more ram to play with, and if your not running over 15 apps simultaneously then most likely this increased amount of ram will make your device faster, since its more unlikely that system needs to page your background apps in swap
