I'm curious as to why with a system like Scylla (that I assume shares the same replication properties as Cassandra which my experience is based off of here) you can't just use the local SSDs and absorb the disk failures. If you space things out across AZs you wouldn't expect to lose quorum and can rebuild dead servers without issue. Is this to run things with a replication factor of 1 or something?

I've done this in past roles on AWS with their i3, etc. family with local attached storage and didn't use EBS.

This is indeed what we (ScyllaDB) do, pretty much everywhere. It works great for 95% of our users. Discord wanted to add a level of guarantee since they observed a too high level of local disk failures.

Yikes! Wonder what's up with GCP in that regard.
