Performance - Access Time

As you can see, the neither the controller card, nor the ATA-133 interface itself has any impact on the drives' access times. No extrapolation is really necessary here. As was to be expected, the increased bandwidth offered by ATA-133 won't affect access times at all.

The results from the DiamondMax D740X are impressive, though. Maxtor has managed to shave off almost an entire millisecond versus its previous generation drive. While it may not sound huge, we're talking about a 7% improvement in access times. It's even more impressive when you remember that a large fraction (over 4ms, on average) of that access time is due to rotational latency, and cannot possibly be reduced without increasing the spindle speed (10,000 RPM IDE drives, anyone?).
