Is it 19ms access >or 12ms? The ACTUAL average access speed of the Quantum 40/80/105 drives is 19 ms. However, Quantum has a 64k cache on the drive which, when enabled, lowers the access time to an optimum 12 ms. Anyone know if that 12 ms is constant, or does it depend on how data is stored, the kind of demands applications (i.e., database vs. word processor) make on it, etc?
