Ok, I prefer to use software which is future compatible, like ZFS, which is 128-bit.
“The file system itself is 128 bit, allowing for 256 quadrillion zettabytes of storage. All metadata is allocated dynamically, so no need exists to preallocate inodes or otherwise limit the scalability of the file system when it is first created. All the algorithms have been written with scalability in mind. Directories can have up to 248 (256 trillion) entries, and no limit exists on the number of file systems or the number of files that can be contained within a file system.”
> Directories can have up to 248 (256 trillion) entries
It took me a minute to figure out that this was supposed to be 2^48, but even then that's ~281 trillion. What a weird time for the tera/tibi binary prefix confusion to show up, when there aren't even any units being used.
Someone did some back-of-the-napkin math and calculated that to populate every byte in a 128 bit storage pool, you'd need to use enough energy to literally boil the oceans. There was a blog post on oracle.com that went into more detail, but no link into Oracle survives more than 10 years.

Don’t want to hit the quadrillion zettabyte limit..
