Pic: One gigabyte over 20 years


1gb.jpg

One the left, a one gigabyte IBM hard drive circa 1987. On the right, a one gigabyte SD card circa the last sale at Best Buy, before they got all the latest Micro-SD stuff in stock. Twenty years equals about twenty pounds from the looks of things. Found via Forever Geek.

Knowing IBM pricing, the owner is probably still making payments on that 1GB IBM drive, better hook it back up!

(sigh) This is from the days when computing was done by real men, and the junior operator did the pizza run.

I started in this business 40 years ago. At that time, a Gigabyte would have cost $50,000,000 for disk, for RAM $1,000,000,000 (1 billion bucks) and taken acres of computer room floor.

For fun and profit we pulled magnets from the DASD units and used the magnet to troll for fishing reels at the bottom of Lake Houston. It made for a fun morning when the fish weren't biting. Geo

This reminds me of when I worked for the Navy in 1970 on a computerized phone system. We had memory frames (toroid) that each held 256 bytes (yes, bytes) and weighed about 20 pounds each. It would take 3906250 of these to make a gig. That would weigh 39062.5 tons. Slightly more than an SD card.

I think that was a HDA (head disk assembly) from a 3380 IBM drive. If I remember correctly, those weighed about 80lbs. Time wise your close, late 80s (hence the J designation - which was the higher speed unit that came out a little later than the initial 3380s). See - http://www-03.ibm.com/ibm/history/exhibits/storage/storage_3380.html The larger cabinets in the rear each contained 2 HDAs. Four cabinets are shown in the pic. In fact, I seem to remember some advisory on the unit that said it required two people to put in place. And boy do I feel old now..thanks

Yes, at the bank that I worked at we had 12-15 rows 8-10 cabinets deep. First time we had a head crash and the brake assembly kicked in I thought someone dropped a bomb on us. definitly more like 80 lbs. Ahh those were the days...Along with the NCR dishwashers

We old guys have one advantage. We appreciate and enjoy the significance of this. I shake my head in amazement everyday when I walk into my office at home and see my 1.2 Terabyte PC sitting on my desk. And it was under $1K.
