    OK, so I have a very large NDS folder full of games and saves, about 2.66 GB last I checked. Now, the card loads them rather slowly, about 12-14 seconds to load the folder on my 8 GB cards (tried on Sandisk and A-data cards), but about 3-4 seconds on my A-data 4GB. Anyone else run into this kind of problem?

    So far as I'm aware, the only solution to this is to split your games into folders, i.e. A-F, G-L, etc.

    Try reformatting the card with the Panasonic SD Formatter. For me, it made the memory card load up literally 5 times faster than when it was formatted with Windows.

    use high allocation size, i think rpg takes 32kbit allocation as most, wont do 64, that sped up greatly on my sisters ttds, i dont know how rpg would handle it since ive always been using 32kbit, and i have 4gb full of roms and it doesnt take more than 3-4 seconds to load of micro

    This is the reason I use many 2gb sd cards works quicker and find the files

    Man, Destructobot, you are just too awesome for words. This solved my problem perfectly, the folder's loading in 3-4 seconds on my 8GB a-data card, thanks a bunch! [​IMG]


    (BTW, in case you cared - the GBA Backup Tool 0.2 does a better job at backing up EEPROM saves, cart_save was screwing up some of the headers, I haven't necessarily had that problem with GBABT .2)

    I used cf_ds.nds to measure reading times, and the access times are about twice as fast:

    All times in microseconds (read: 544 microseconds to read 512 bytes of data, 4396 microseconds to read 4 Kibibytes of data):
    Standard Windows Formatting:
    sequential 512 B/4 KiB/16 KiB: 544/4396/17629
    random 512/4/16: 1166/4532/17734

    Panasonic SD Formatting:
    sequential: 512 B/4 KiB/16 KiB: 267/2174/8763
    random: 512 B/4 KiB/16 KiB: 529/2194/8808

    That's pretty much identical results to my Kingston 1GB microSD with standard windows formatting. Gonna try reformatting that Kingston...no noticable change from previous tests. In fact...it's a bit slower than what the Adata is doing, but I'm not comparing apples to apples here.

    This thread should be stickied. The difference in speed between Panasonic formatter and Windows formatter is *massive*. SDHC is easily as fast as SD now.

    I recently added the formatting info the the AKAIO wiki, in the tips and tricks area.
