CephFS default data pool on SSD vs HDD

Would you make the default data pool be stored on SSD (replicated x3) instead of HDD even if you are storing all the data on HDD? (also replicated x3)

I was reviewing the documentation at https://docs.ceph.com/en/squid/cephfs/createfs/ because I'm thinking about recreating my FS and noticed the comment there that all inodes are stored on the default data pool. Although it's kind of in relation to EC data pools, it made me wonder if it would be smart/dumb to use SSD for the default data pool even if I was going to store all data on replicated HDD.

The data pool used to create the file system is the “default” data pool and the location for storing all inode backtrace information, which is used for hard link management and disaster recovery. For this reason, all CephFS inodes have at least one object in the default data pool.

Thoughts? Thank you!
