@cortland, I remember working at a place, where we had just gone from VAX to MicroVAX and hat a box the size of a desk drawer unit, which was a VAX with 4GB storage, a huge amount in those days.
We then got a contract to run an IBM installation for another customer and their hardware started to arrive, there was a huge (6' high, 2' - 3' wide and the same deep). I asked what that was, the IBM op said "a DASD", I was impressed, if my desktop had a 120MB drive and the MicroVAX had 4GB, then this must have had a HUGE capacity. When I pointed at the MicroVAX and said, well that has 4GB, what capacity does this thing have, being at least 12 times the size of MicroVAX and just being the drive? He turned a little red and mumbled 500MB.
