SD cards, just way too little capacity...

Only in school, early 90's when we only had C64 as School Computers. But my first PC (386) already had an 3,5" Floppy Drive so I had 1.44MB and an huge 210MB HDD. Never got the HDD full by tha way... xD

Howmany Capacity had this? And how much was actualy fitting onto ordinary (MC) Datasette-Tapes? I never had one of these tape devices.

On a 2400 foot reel at 6250 cpi it maxes out at around 170MB. Realistic safe capacity with a decent leader and ensuring you don't run out of length is around 150MB per tape.

Those are far far different from "Datasette-Tapes". Unless you were involved in mainframe data center work prior to 1995, you're unlikely to have ever encountered 9 track tapes.

If you have ever seen a movie from the 1970s or even 1980s where they show a 'computer room', they probably had big server racks of these types of drives. I think they appeared in several James Bond films.

The drive that I have is one of the most advanced ones ever built and comes from somewhere between 1983 and 1985. It likely cost the local university $20,000 +/- when they bought it new. I got it in a pallet of computing equipment at a university auction back in the late 90's.
 
ahh archos, mate of mine bought one of those, still uses it for films on holiday... innit great how quick sci-fi become the device in your pocket ;)
 
We were using DLT tapes in around '95 for backup purposes (connected via SCSI to a server on a token ring network). Not sure how long those tapes were, but they held 10GB.
