To add: LTO speeds are currently in the 300MB/s range: if you want > TB size storage you likely don't want ~100MB/s for regular use. I work on systems where we are regularly writing multiple tapes of 5+ TB and if you get only 100MB/s you're waiting hours and if something fails or gets stuck you can be thrown off schedule by more than a day very quickly. Even at the current 300MB/s speeds it's very slow. If personal archival or even small-scale archival is your interest getting network storage is probably easier, faster and cheaper. What's more, is that you have to keep some kind of inventory of your tapes so you know where to find data if you ever need it. Depending on the size of your collection you can be looking for even more expensive equipment to manage the archive of your archives.

Anything even remotely random is going to have far slower archival times, unless you have archival software that does parallel I/O. (In my experience, not many archivers do this.) Most production tape installations include dedicated disk storage to act as a buffer for the drives. You archive to disk first, so that your drives aren't tied up, and then write the now-sequential data to tape.
