It looks like the new UFS 2.0 storage in the S6/Edge is quite a big jump forward. The difference in speed compared to the eMMC5 storage we find in other top phones is quite impressive and should make a pretty big difference in some use-cases. It's a bit like jumping from a slow storage like a hdd to a ssd.
