LTO is pretty fast, though it doesn't seem to have the fast search
that was about the only thing I liked about DAT/DDS tape. But
the cost of LTO for a home system is hard to swallow. You could get
about a dozen USB drives to rotate for a similar cost. Tapes are
nice for archiving or long term storage though. Their data format
seems less likely to change over time than disk.
