The best durability is probably achieved by Amplidata, but it does not matter. You need to do the same calculation for your meta data, which is probably not erasure coded. If you lose this, you don't lose your data, but you no longer know where you put it. So you probably add your meta data to your data as well in some kind of recoverable format. That's fine, it means that you can harvest the meta data again. But how long does this take ?
