AWS already had a “reduced redundancy” product, though last time I looked it was basically the same price as normal storage.

And the “S-IA” thing in your table looks odd as it actually costs more than normal storage.

And doesn’t “IA” stand for “infrequent access”, which is a different dimension?

Some clarification would be good.

edit: it seems this new offering has reduced availability but the same durability as regular storage, while the reduced redundancy product (which has uncompetitive pricing, so seems deprecated) has reduced durability.)
