Honestly the network-attached storage only ever made sense with HDDs, it's ridiculous to have to pay 10x penalty for both iops and latency just for some "operational flexibility". You get way simpler and much more robust architecture if you just stick to local NVMe and replication -- not that you can forgo one in the (also replicated) network block storage solution anyway...

NAS/SAN still make sense when you need to share storage between multiple DBs for cost efficiency: most application DBs are tiny compared to the size of an SSD.

Mostly agree, but then you have to take care of replication, failover, and backup. By using a replicated block storage, you can mostly externalize that problem.

I can't be the only one that always has to set up a separate backup system in addition to the RDS automatic backups, because it uses a weird format and is slow.

And because those backups lifecycle is usually tied to the instance itself. Someone deletes your instance and your backups are gone as well.

		It’s kinda crazy that this is the case, and then they make it sooo convoluted to copy those backups elsewhere. Typical cloud.
