Amazon S3 Reduced Redundancy Storage
May 22nd, 2010
Amazon this week announced a new cheaper storage option that has reduced guarantees for the durability of stored objects. Amazon calls this Reduced Redundancy Storage.
It’s 99.99% durable instead of 99.999999999% durable per storage object.
Interesting that they not only measure availability, but also durability of data. I’ve never seen that before. Not that I think the numbers are based on reality at all, but it kind of makes me nervous about how durable the storage of my bank’s data-center is ;-)
