If you’re after a non-Premium file share that is from 5 TiB to 100 TiB in size, you
need to enable the large file share option. While it creates a very large file share, it
limits your redundancy option to only locally redundant and zone redundant. Pre
sumably, this is to limit vast amounts of data going over larger distances, such as
for geo redundancy. Once you’ve converted to a large file share, you can’t go back.
That file share is a big one forever, but you can enable it on existing accounts too, as
long as they are set up as locally redundant or zone redundant, of course. Premium
file shares support 100 TiB from inception, so this option isn’t relevant for the Pre
mium tier
