"Another interesting change in hardware is the rate of increase in capacity versus the rate of reduction in I/O errors per bit. In order for a disk to have the same overall number of I/O errors, every time capacity doubles, the per-bit I/O error rate must halve. Needless to say, this isn't happening, so I/O errors are actually more common even though the per-bit error rate has dropped."
I don't understand how these are connected... Isn't the I/O error an artifact of reading or writing, and not a defect in the hardware? If it is, then it hardly matters, as you only care about I/O errors per second, or per bit read/written, not about I/O errors per bit of the total disksize.
Or maybe I misunderstood something?
