I'm thinking that micro SD-cards, because of their high storage density, are probably especially susceptible to bit rot. So I thought I might give ZFS a try. (I'm open to alternatives..) However, I also read somewhere (can't find the link anymore) that SD-cards often come with somehow specially aligned filesystem formats from the vendor and therefore should never be formatted if not absolutely needed.
(I read this question about flash filesystems but in the comments it says it makes only sense to use block-level filesystems on SD-cards, since they emulate a block-level device in hardware.)
Any advice or links? I'm on Mac OS X and my Kingston micro SD-card is currently exFAT formatted by the vendor. I'll use to hold my iTunes library and a few rarely-accessed files.
