What is specifically meant by t[1|2].micro AWS instances having low I/O bandwidth?

What is meant by this low I/O bandwidth constraint? Does Amazon give a lower priority to I/O operations for t[1|2].micro instances?

What I'm asking specifically is, does Amazon limit the I/O intentionally or is the low I/O a result of the limited resources of the t[1|2].micro instance? From what I've read on Amazon, AWS EBS-based magnetic drives have IOPS between 40-200; does the t[1|2].micro instance then provide lower transport capacity per I/O operation?

This is entirely confusing to me b/c a 7200 RPM drive has IOPS between 75-100 on a desktop computer. Why then would IOPS between 40-200 on a t1.micro instance be considered low?

Thanks in advance for your help.
