holly beep, who cares. I can say that tape did take a long time, an did often fall over, dirty tape heads, bad alligment etc. To say tape did not have problems is even more crazy than somone pretending it did
Over time turbo loaders reduced loading from tape dramatically, so the long time issue wasn't so much compared to disk.
As for reliability, the 1541 suffered from dirty heads etc just as much as datasettes, and I never had an original tape fail. Backups sometimes did, but copying tape to tape wasn't lossless so that was understandable.
If you kept your datasette clean and maintained it was an extremely reliable storage medium. I have 30 year old tapes that still load problem free as they have been stored well. I bet there are floppies that also work after this time and those that don't.
