The whole of Aminet has "recently crossed the 30 GB barrier" (Quote from Aminet). Puts things into perspective a bit.
Then there's probably 5GB of games (commercial and PD).
You are thinking way to small my friend. I had 5GB of Amiga software (games + busines + art + textures + fonts + sounds + music) by around 1993 and I certainly did not have everything made.
Today I have 32GB just of Amiga CD gamez and I don't have all of them.
Everything else that exists besides probably takes it up to 50GB at most.
I have around 8GB of Amiga fonts.
I have something like 700GB of gfx and sounds and we constantly make more.
With 2TB you could store a lot of digital music, or photo's. He doesn't necessarily want to strictly store Amiga stuff. He could want to store all of his digital camera photo's. That would be a good idea, as I'd personally trust my data on an Amiga more than any other computer.
You make a great point!
But why would digital music and photos not count as Amiga stuff? Commodore machines practically invented digital music and digital photos.
The first digital music I ever heard that didn't hurt my ears was on the C64. The Entertainer Demo, Frogger, Frantic Freddie, etc. The first digital photo I ever saw that looked like a digital photo was an Amiga 500 showing the NewTek Demo Reel 1 and 2 with Laura Longfellow, Kiki Stockhammer and the Ragu Spaghetti Sauce bottle. Do you not remember any of this?
