You're overgeneralizing from one specific type of raid, aren't you?
The comp.arch.storage FAQ explicitly states that "raid level 1...
shorter latency... since resolution can be from any of multiple disks".
Other raid configurations increase latency (raid 3 increases latency
from an average of 1/2 revolution to near 1 revolution); but noone
really uses those.
