It's unclear if even a sample was provided, but yes, in general with Wikileaks the idea is to throw all the data over the fence to them, and let them take care of the rest. Trying to negotiate terms of how the data should be released etc is a non-starter.

why would you upload it anywhere? Just send an encrypted micro sd card by mail.

Cool, say you've done so despite obvious issues (no microSD is over 1 TB, since TrueCrypt is no more there's no obvious trusted encryption software for that sort of thing, then there's borders, being on a security camera at a post office, etc).

Which address would you ship it it to so it reaches Wikileaks?

So you need to send two microsds, fine. You'll probably want to use something more trustworthy like luks with a detached header and a largeish offset. Finally, drive some tens of kilometres and throw it into a mailbox somewhere in the fields at 3 o'clock.

I don't know what address wikileaks has, but then again I never tried to contact them.
