The time accessing to data in HDD equals to that the seek time plus the latency time, not including
controller time overhead. But
for SSD, the latency time is 0, and the seek time is very small. Most of the
time is consumed by controller overhead.
The access time definition here is measured from the last byte of host command received by drive to
the first data byte sent to host by drive in read operation.
