I don't use Konqueror, but now I know about the option.

Thank you for this, I'll look into it as that looks like what I was 
looking for.

Normally, SD cards come pre-formatted with a FAT16 file system, setting 
the upper limit to 2GB.

SDHC is the next generation of the SD standard, and it allows cards 
larger than 4GB, which is the limit of the old SD standard.
Also, FAT32 is the default file system it comes with and that also 
breaks the previous 2GB limit.

Kingston products are OK in my experience, and cheap prices on SD cards 
are usually just because of very low speeds.
