    Being able to switch SD card during dumping would be really helpfull. If you manage to make that work then dumping to USB is not important, only nice to have :)

    When the dump is finished is there any message? or we'll just be back at system menu?

    It's normal, your sd card is in FAT32, you can't have a file most big of 4GB, here it the mlc in 15 part, put all part in a same folder and open the cmd and type

    copy /b mlc.bin.part01 + mlc.bin.part02 + mlc.bin.part03 + mlc.bin.part04 + mlc.bin.part05 + mlc.bin.part06 + mlc.bin.part07 + mlc.bin.part08 + mlc.bin.part09 + mlc.bin.part10 + mlc.bin.part11 + mlc.bin.part12 + mlc.bin.part13 + mlc.bin.part14 + mlc.bin.part15 + mlc.bin.part16 mlc.bin
    You will have mlc.bin 29,1 gb, you can delete all part
    64gb for a wiiu 32gb or 16gb for a wii u 8gb

    And all of that is required for NAND restore via hardmod? Like if I'll delete some data to save space on my hard-drive is it ok or I'll need the whole dump?

    Thank you again for your answer, but I need to 100% sure. I asked about the number of parts because I've read about 16 parts, but I only got 15. So I'd like to know if I have to dump mlc again or if it is correct. Thanks in advance.

    Paid service which will unbrick your Wii U via Hardmod if you have required files.

    I just dumped the whole Wii U internals to my 64GB SD card thanks to EyeKey for his great attribution! It took way more than 1 hour and once again shows how slow the Wii Us memory and/or SD bus is! I guess it was about 7 MB/s for the 30 GB to be processed. I have seen faster install times using SD (brazilian) to USB transfer.
    Does anyone have a clue why reading the several NANDs is so slow?

    Is there a tutorial for restoring the different parts (SLC/SLCMPT/MLC and so on) just in case I brick something in the future?

    From my understanding the SLC is where the firmware is stored.
    the SLCMPT is the vWii?
    The MLC seems to be the game/save storage of the Wii U
    And the OPT and SEEPROM seem to be unique parts of the Wii U encryption and decryption routine, right?

    Thanks in advance for helping me out!

    Yes, you are right: SLC and SLCMTP are situated on a TSOP NAND Flash chip, MLC is another Chip, quite similar to a SD-Card on a BGA Package
    To restore SLC and SLCMTP you have to use a Teensy 2.0++ soldered to Testpoints on the Motherboard
    To restore MLC you have to use a SDCardreader and some wiring to the Motherboard
    The Restore Process is noting done easily so keeping the Backups and not forcing any Harm to the System is the best ;)
    -Take a look @ https://gbatemp.net/threads/successfully-dumped-wiiu-emmc-nand-with-hardmod.457165/ for Details on hardware-flashing/dumping/restoring.

    AFAIK OTP and SEEPROM could not be accessed via Hardware, they can only obtained from a working system via Software and are needed for manipulating the Flash dumps (i.e. Unbricking a CHBC brick)

    When you're installing a game from SD you are reading the SD card, whereas dumping the NANDs is writing to SD. Generally writing to SD is slower than reading from it (you could test that on a PC). So it's likely to be the writing to the SD that is the limiting factor, not the reading of the NANDs.

    But, who cares?- it has to be done only one time per console to have the backup done. Absolutely worth the wait ;)

    My SD Card Van easily handle 30 MB write speeds (seq.). So it shows how weak the internals in the Wii U are.

    It also depends in the Method how the dumping is done on software-side. Take a eeprom dump in vwii for comparsion which lets feel dumping mlc in wiiu is at lightspeed ;-)
