[Rakk] My understanding is that discs can recover lost blocks if they are in the right sort of configuration, and Flash has hardware redundancy built-in for its peculiar fail modes, so I guess the answer is "Yesnabe".
But in order to get the sort of speed and reliability from spinning discs that tape offers (in streaming mode - important specific there) you have to "waste" a lot of discs. Personally I think tape is neat just because of the robot silos. Technology should have moving parts to provide visual interest. Today's tech is all solid state in boring boxes. Some years ago I toyed with the idea of using tiny motors like the ones in toy helicopters to drive lightweight gear trains, the whole on an appliqué that could be stuck to a tower casing to make it look like it was doing useful stuff. Might still try that.
