Difference in how formating an SD Card?

[odoll]

All,

I want to have the (kernel and) filesystem running from an SD card. Beside keeping the logging volume low I was wondering if I have to care about e.g. the FS type and block size to maximise lifetime and IO performance.

So far I used ext2 for the kernel partition and ext3 for the FS, but didn't bother about fdisk chosing a block size matching the cards physics?

Lifetime is maybe not such important as (1GB) SDs are cheap anyway (having regular snapshops).

I used it for my USB flash drive but not for my SD card, and I used ext3 on both.
