I've never had an LTO3 tape that I wasn't able to restore successfully from. I *have* had Seagate
1TB drives that required special measures (firmware upgrade and multiple power cycles) to be able
to read from, and most people seem to have hard drive horror stories from one manufacturer or
another. Drives in RAIDs can be very reliable (barring correlated failures), but linear tape
technologies are also *very* reliable and fast. I don't think tape is obsolete by any stretch, and it
complements rotary drives as a backup medium. Rotating head tape technology for critical data
storage is an abomination against God, however.
