    Hello all... Ive got EZ4 (Normal-Version)... and a Sandisk 1Gb Ultra2 card..

    now im testing wich Fat mode gives me the fastest speed in the ez4.for stuttering etc or loading times.
    anyway Fat32 isnt possible as we know.

    But....there are Cluster sizes.. i can choose from 8,16,32 and 64kb Clustersize.. (When i do formatting)

    What is the best Cluster - Size to take with the best results...????


    Greeting from XeNo

    It has been figured out that card speed does not matter much as the maximum speed the NDS can hanle is much lower than 9-10MB/S. With 9/10MB/S you could easily handle an HD-Video and, for example, the castlevania is anything but a video in high definition - its really low-res and low bitrate. So the bottle necks are most certainly software side, or in the way a certain flashcard handles the media. Its just simple maths, if the castlevania movie would use a hypotetical "low" 1MB/s (which is still much lower than the previously stated 10MB/s) it would still exceed 100Mb - and the castlevania rom is 64MB PLUS game.

    It's all about software/patching.

    Formating is done by

    "Format K: /F:FAT /A:64K"

    would format drive K with the FAT filesystem and with 64Kbyte clusters...

    In general larger cluster size is better for memory cards. Files are split up across these clusters, and larger clusters means less clusters to read a single file from, which in turn usually means it's quicker to access. Less fragmentation.

    Now there can only be (part of) a single file in a cluster, which means that you lose more space with larger cluster sizes. One hundred 32KB files would on 64KB clusters actually use 6400KB, instead of 3200KB. For 96KB files you lose 50% (64+32, 32KB left in one cluster).

    Also you can run into issues with really large cluster sizes. And the available cluster size options are affected by your choice of file system, and the storage capacity of the card.

    If you've got a card larger than 2GB you must use FAT32, since FAT16 can only do 2GB (and some 2GB cards seem to demand FAT32).

    In the DS FAT32 seems to work better for some people, even though FAT16 "should" be quicker if you can use it. No idea why that is.

    The way most people test their cards is to watch the Castlevania intro and check how well it plays.

    on ez4 it more about they need software-speed improvement...so ill wait for that.

    NDS games best performance is 64kb cluster.
    after i tried couple of games...
    for the ez4 its the best i dunnow other cards

    FAT16 and 64kb cluster it is.

    FAT16 and 64KB is the "logical" choice for best performance, so it's not surprising when it turns out to be so IRL as well.

    how can you check what cluster size a memory card is using?

    This is only true if you're using an older version of Windows.

    Windows XP added support for FAT16 partitions up to 4GB in size.

    That is true, but doesn't help the DS community since you cannot use it in your DS. Your computer might be able to read and write to the 4GB FAT16 card, but your M3 or whatever can't. But sure, for perfect accuracy it's a valid point.
