[Discuss] SSD drives vs. Mechanical drives



from my old days of doing performance analysis of round brown and spinning
devices,
performance from lack of seek, rotational delay, and head positioning time
(track to track)
should take quite a bite out of the delays associated with them.

The only delays I could think of should be buss access and addressing
delays caused
by buss contention or CPU requirements to calculate required access
information (but hey,
disks had that too, linear sector access got rid of most of the CHS
calculations though - that is
cylinder head sector).

Sorry, this provides no new information, but it feels good to remember as
semi-useful what
I used to know :)
