Yes, a single disk in a VPS or cloud provider has durability concerns. That's why EBS and products like it that pretend to be a single disk are actually several. Instead of relying on multiple block devices, though, we create that redundancy at a higher level by relying on multiple MySQL or Postgres servers for durability, each with a local NVMe drive for performance.
