Has anyone compared disk to usb hdd/nand?
I have started playing on NAND and noticed a increase in loading speed when I switch to disk. Also, sometimes, when picking up a new item and a popup window informs you of that, the disk is not quick enough to load the 2D image of the item, leaving the box containing the image empty for less than a second.
Then I compared the install speeds to NAND and USB (SSD, capable of 100MB/s+ writes and 400MB/s+ reads on USB 3.0, so it should max out WiiU's USB just fine): Installing the ~9.9GB game to USB took ~1104 seconds (~9.2MB/s), while it took a whopping 2097 seconds to NAND (~4.8MB/s). Neither are fast and are much slow than they should be... It might just be that the tool is unoptimized, writing to either... but who knows. They definitely won't win any benchmarks xD
Next i tried moving/copying a ~400MB game from NAND to USB and the other way round:
NAND to USB: 65 seconds (6.15MB/s)
USB to NAND: 89 seconds (4.5MB/s)
Guess even Nintendo sucks at writing and maybe reading? not sure what to make of these numbers...
Next up is in game benchmarks. I teleported from Great Plateau to Kakariko Village and back again. Heres the time it took (from triggering the travel and the very end of the loading screen, right when the game fades back in. Time in between, like game interaction, opening map and so on are not in these numbers)
DVD: 68.49 seconds
NAND: 68.77 seconds
USB: 61.43 seconds and 65.21 seconds
A single run cuz I was getting bored with this shit, so don't take these at face value, as times varied greatly when I tested it a second time on USB
Also, unlike when using the DVD, the WiiU keeps quiet
P.S. none of these fix any framerate issues. It is the CPU/GPUs fault, not the storage. I also haven't experienced any sound issues so far, but I didn't test USB gaming much yet
P.P.S. only thing missing now is running the game off the SD card... but im too lazy to do that now.
