@TurdPooCharger I don't understand why a bigger SD card would be slower ...
The bigger the SD card, the bigger its partition table. This table has records of all the files and folders contained on the card and maps out how much & where the free spaces are located.
Modern computers and smartphones do not have noticeable lag loading up or caching the table for big SD cards because they have very fast bus speeds reading and writing between the SD card ⇄ main [ hard drive / SSD / internal storage ].
If we were to infer from the age of the original 3DS model (+9 years old), Nintendo's history of using last gen tech to keep their hardware production costs down,
official stated support of up to 32 GB or
SDHC {
SD Association specifications of capacity paired with file systems} {recommenced upper limit for FAT32}, the pre-bundled 4 GB (micro)SD cards are always
Class 4 [
example - iFixit n3DSXL teardown, Toshiba brand card, C4], observable average write speed of around ~1.5 MB/s when FBI installing CIAs on even the New 3DS series, and the slow introduction + adoption of
SDXC cards [64→128→200→256→512 GB], it's safe to conclude that the 2DS/3DS systems weren't designed from the onset for users having a large collection of games..
Keep in mind that any changes done to the SD card (adding, deleting, moving, renaming, copying items) means the partition table has to likewise get updated to reflect those changes. That means there's a constant back-and-forth juggling between the SD card and 3DS system keeping track what's what and what's where. For increasingly bigger SD cards (128 GB and up), increasing the cluster size from 32 KB → 64 KB helps to reduce loading time is like having
fewer slices to keep count for a given pizza pie.
So I did all that, I formatted with GUIformat in FAT32 64 Kb, I did the test which lasted a good half hour (without error)
Hmm... Did you reformat the SD card along with the other three (3) programs in that specific order? A single reformat (ie, only guiformat and nothing else) may not produce a clean setup.
Here are the reasons behind quadruple reformat.
Does your computer happens to be premium or cutting edge, like a gaming rig or workstation? A finish time of about half hour (give or take another 15-30 minutes) fully writing and reading back a
SanDisk Extreme 128 GB microSD card seems reasonably possible if this was done on a computer that has a UHS-I reader or on a high end SD-to-USB 3.X adapter.
I put everything back on the SD card and it's still slow, Do you have a good SD card to advise me? For test, because the problem may be with my Sandisk?
Time this with a stop watch or phone.
If a quadruple reformat in 64 KB cluster size was properly performed, the
emptied out card passed H2testw, there is at least 15 GB of free space, and the number of installed CIAs (HOME Menu titles) is approaching no where near 300, expect a load time of about 30 seconds from the moment the (POWER) button is pressed until the HOME Menu appears or lights up.
As far as suggestions for a different brand or model microSD cards, check my signature and find the equivalent listings from Amazon USA ⇄ Amazon France.
