It all depends on the usage of your card. FAT16 works better for cards that are used for Multimedia purposes such as video and music. FAT32 is best for just storing data.

Mostly I use the SD card for Media.

Is it the access speed higher with FAT then ?

The actual access speed would remain the same but with FAT32 there is more file system overhead that might give you a small performance hit.

The primary benefit of FAT32 is that it divides your disk into smaller clusters. This means you will waste less space on a larger drive with FAT32. I won't bore you with the technical reasons but you can research "slack space" as it relates to file systems if you want more information. There are other considerations as well but none that would provide a noticable increase/decrease in performance on our PPC's.


whitelyt accurately pointed out that multimedia files would benefit from FAT16 (FAT is also known as FAT16) This is due to the decreased filesystem overhead. FAT32 works better for storing everday data because the smaller sector size (less slack space).


Either one will work just fine on our PPC's. Keep in mind that FAT16 will only work up to 2 Gig's, then you need to switch to FAT32 or NTFS (if it's ever supported).

Hope that helps.
