IOMeter
IOMeter presents a good test case for both seek times and command queuing.

You might think that a strong showing in our multitasking tests would set up the 1.5TB 'cuda nicely for our multi-user IOMeter test patterns. You'd be dead wrong. The one-point-five is quite disappointing in these tests, falling behind not only the fastest 7,200-RPM drives in the bunch, but also the terabyte 7200.11. Only terabyte drives from Samsung and Hitachi are slower here.

At least the new 'cuda doesn't consume many CPU cycles in IOMeter, but then none of these drives do.
