I just purchased one of these guys to test and see if we can use an external hdd(with external power supply)formatted in fat32 with this device and the Wii U. I will report on it as soon as I get it.
Nice. If it works, I'll probably end up getting one too. It's really cramped on my 32GB SD card...
This is unlikely to solve any of the SD slot's problems including limited size and loading speed. It says it is limited to 32GB (SDHC spec) which might not be a hard limit but I wouldn't get my hopes up
As for the loading speed issue, I've done some tests. The first was if SD as a format has some inherent reduced ability to transfer multiple small files at once. To do this I copied the entire directory of Star Fox Zero to both a FAT32 64k cluster formatted SD card via USB2.0 adapter, and a FAT32 64k cluster formatted USB2.0 HDD, then transferred the files back to my PC to judge the read speed. Both SD and USB were nearly identical in this case, taking 2 min 23 seconds and 2 min 22 seconds respectively
The conclusion that I'm drawing is one of two possibilities: 1) the SD redirect code in loadiine causes substantial file access delay because of the overhead, 2) the SD card slot itself is simply garbage
The latter seems unlikely since the eMMC itself is on the same SDIO bus, which means SD card access should be nearly as fast as the system's NAND. (limited by your card's specifications)
Regardless, in either case, this could only possibly slow down loading speeds, and it almost certainly won't increase storage space beyond 32GB

This is all very possible. I'm assuming that there will be an additional delay with file access but I'm also banking on the possibility that a hdd with a bigger capacity than 32gb formatted in fat32 will work just like a sdxc card formatted in fat32. So far no one has tried it and all I have seen is people speculating about the possible outcome but no actual test. Just taking one for the team.
The most important thing, slow down loading speed, solving this it's enouh.
If work he could make a video comparison.
