Hey there, i tried many SD Cards on my O3Ds XL A9hl out to see if FBI installts my .Cia Files faster. I used a 2GB SD Card and FBI needed 5 Seconds for 1MB! It started at 0.00MB and goed up to 1MB in 0.25 Steps (It showed me 0.00MB, 0.25MB, 0.50MB etc.. up to 1MB and i started counnting). Then i used my ORIGINAL O3Ds XL 4GB SD Card and the Results was the same like the 2GB SD Card... Ago 2 Days i received my new 32GB SD Card (Class 10) that i bought NEW with Guarantee, and the Results with FBI now: It starts with 0.00MB, and goes in 0.25MB steps up, but much faster this Time (Same like before, FBI Shows while installing: 0.25MB, 0.50MB etc. in Steps but the Numbers change in few MILI-Seconds, so thats very fast now). It needed 1 Second to go to 1MB, but this is still not enough for me... I used a very expensiv FAST SD Card from my Dad (64GB) for testing and it still needs 1 Seconds for 1 MB!. The PC Write Speed Resulots of the SD Cards: 2GB: 8MB Per Second 4GB: 15,4MB Per Second 32GB: 20MB Per Second 64GB: 40MB Per Second. I used a Test file to see how fast the Write Speed is from PC to all of the SD Cards. Well, my Question is now: Is my FBI installing slow because my 3Ds cant Write more than 1MB in one Second ? the last 2 SD Cards maked only 1MB Per Second in FBI, but the Cards are much faster on the PC. I guess its because the 3Ds.
