</div>I recently moved 5TiB of data from the US to London over sneakernet,<br>
luks crypted HP SimpleSave 2 TiB disks each. Just to make sure we made 2<br>
copies and sent them via different courier companies. Worked out quite<br>
well, in that we were able to move the data across in 5 days time( from<br>
ordering the disks online, to receiving them here in London ).<br>
