For comparison, this is about 16 exbibyte.
According to <https://en.wikipedia.org/wiki/Byte#Multiple-byte_units>,
that's more than the global monthly Internet traffic in 2004.

According to <https://what-if.xkcd.com/31/>, 16 exbibyte would be about
17 million solid-state disks.  Even though this ignores deduplication,
this seems rather expensive. 

My guess is that the size of a store item was misrecorded somewhere.

Greetings,
Maxime.
