If you are asking for the price of everything after I download it, it depends on how much of it that you want. In "sizes.txt" - I don't have most of this data (yet?):
> Offsite files, not counted with size:
> 15T Furry/Videos/YouTube
>  Pony/Tumblr archive
> 32T Pony/Videos/Fan-made/YouTube
> 86G Pony/Videos/Media/YouTube
> 617G Pony/Videos/Official/YouTube
>  Pony/Website archive
> [...]
> 324G ⁄mlp⁄ (SUM)
> 4.8T Shared by other people (SUM)
> 21T Pony (SUM)
> 2.0T Furry (SUM)
> 219G Filly Funtasia (SUM)
Not sure what exactly the contents of "Shared by other people" is. (Further reason to download it: the guy who currently has these files said he does not have any backups of the larger datasets.) Total of everything above (plus the onionsite which is like 200GB to 900GB, guessed at 500GB) = 15000+32000+86+617+324+4800+21000+2000+219 = 76,546 gigabytes or 76.5 terabytes.

Otherwise, I would expect you cover shipping cost, price of the drives, and plus tens of dollars a profit to me. Plus how many tens of dollars? Whatever you think is fair. My effort is worth at least +$10 per drive. Also I might end up operating at a lose if I work to backup everything locally, so I may not make any profit from this endeavor even if you pay me extra per each drive shipped.
