RAID0 access time

The amount of time required to read the first portion of the data at the given address is called "access time". It depends on the location of data and on the request history (these two parameters define how long disk heads have to travel). Some practial measurements include "maximum access time", "track-to-track (minimum) access time", and "average access time" for a given hard drive model. These specifications are typically provided by the drive manufacturer.
