Ponder needing fewer SSDs/HDDs; smaller systems, fewer or no shelves, 
fewer bays, less rackspace, etc.

Ignoring the various pitfalls of storage partitioning, it can also be 
useful when fewer HDDs/SSDs/bays are available.

NAS boxes being deployed for backups are using 12 TB HDDs throughout, 
and most recently with NVMe SSD cache added. Wicked fast.

The ODS-2 and ODS-5 file system designs don't lend themselves to 
performance, nor to SSD operations.

For what might be replacing ODS-2 and ODS-5 file systems, GFS+ has been 
mentioned.
