Hacking The reason for a special HDD format in Wii U?

[OriginalHamster]

I was thinking what if the reason for a special Wii U format weren't only because piracy but access speed too?
Wii U only use USB2.0 and have to stream alot more data than Wii, maybe a specialized format sure could help to get shorter load times.

I would love to get technical details about transfer speed vs bluray disc, and how it does fare against for example a Wii game transfer speed in a X loader.

I would guess it's only for piracy prevention.
Encrypted drive are now common practice in all consoles to prevent users exploiting vulnerability or even just not allowing user to edit files (save game, cheats, etc.)

I don't think it has anything to do with access speed.

edit:
it's also used to prevent users sharing their files, saves, etc. but usually are individually encrypted in top of the drive's full encryption.
