Question on USP/NSC Power

USP can take a 1 min power dip. (and then we have either backup/destage mode)
NSC-55 can take a 20ms dip. Where as there are no battery supported for the DKA's.
How does this 20ms figure come from, when there are no batteries?

(Is it safe to assume that the disks can withstand 20ms of powerdown due to capacitor etc)
