Soldato
First hard drive I used was in Sept 1982, in a Comart Z80 CP/M system, it was 5MB "Winchester" hard drive...wow Look at all those files when you do a "dir".
I bought a 152 MB harddrive for a HP development platform in the 1988, £4780, I still have the invoice. Worked on the SCSI interface. Came in its own massive enclosure with PSU etc, and in total weight around 20KG. That's approximately £31 per MB, or 3p per KB, must be one of the highest costs per MB that most have come across.
Bought a 2nd hand 55MB one for the same platform £1750 in the same year.
I knew a guy who worked in a data processing centre (I am sure it didn't have that name at the time) when the very first hard drives were introduced. These disks were nearly 30 inches in diameter and span at a scary rpm. I remember him telling me of the day that one cabinet suddenly started clattering and dancing around like an unbalanced washing machine, and then a disk tore through the side of the cabinet and flew across the room. Computing was really dangerous back then!
