You might want to give nilfs2 a try, it should be rather well suited to sdcard storage:

Note that nilfs doesn't do checksumming -- for that you'd have to look at btrfs or zfs. I'm not sure how btrfs is in terms of ram usage, but generally zfs needs lots of ram -- and if you want to get the guarantees it provides for data, you need ecc ram.

Impressive numbers. I'll give it a shot in a few hours on a spare pi and see how it performs. Thank you.
