I have been playing with RPi's for some months now and I'd be anxious to use an SD card (be it micro or standard size) for reliable additional storage space or backup.

Are SD cards reliable enough for normal usage (excluding RPi's brutal power-off which are often prone to corruption) ?

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.
