Thirty gigs on a 386sx is a lot of storage.

I remember DEC hard drives that were the size of today's mini-fridges.

I had a friend in college who inherited some money.  With it, he bought a 10  meg Winchester hard drive.  Around school, everyone was wowed.

But he didn't have the controller.  It was too expensive.  To the best of my knowledge, he NEVER got it to work.  But he had a Winchester hard drive!  That alone got him the chicks.  (Not.)

I have an 8 TB external drive I bought on Black Friday a couple of years ago for $125.  I don't follow the technology much anymore but 8TB is still the biggest personal drive I've seen.  Once upon a time, you'd NEVER have been able to say that after two years.

Some citadel friends and I went to a computer show, they were selling 256meg drives for $256, a buck a meg... what a bargain. This was a big bulky 5¼ size drive. 

My first phone that could use an external micro SD card used 256meg, which I purchased for $36, that was about the size of a dime.

When I bought my first computer, it only used 5.25" floppies.  It came with a software pack (word processor, spreadsheet and BASIC), so I bouhght *ONE* blank floppy disk for $7.00.  92k I think it was.

When I later bought a 10-pack, I learned that we could use a hole punch so that the floppies could be inserted and used upside down, doubling their capacity.  That was a big deal!  We called them "flippies".

It's amazing, when you think about it, what we were able to do with so little memory (64k) and disk storage.  I learned assembly, BASIC and C on that computer.  I wrote and sold games.  A friend and I typed in the hex for a forth interpreter and we actually got it working.  (Must have been a hundred pages of just straight hex.  Lots of fun to debug.  Not.)  Those with the money bought dBase IV.  So that little computer had word processing, games, spreadsheets, databases, connectivity (via 300 baud modem), compiling - pretty much all of the major applications we have today except for color, graphics and internet surfing.  In that respect, computer advances have been really disappointing.  Back then, I'd have bet that we'd be talking to computers like they were people by now, and that people would be spending all of them time in a virtual world more interesting than the real thing.  Being wrong on that last part might be a good thing...
