Prioritize capacity: use drives independently
The standard configuration has 2 × 1TB NVMe drives, each directly connected, for 2TB of raw capacity with no shared storage. If the drives are assigned separately to application data and backups, define their roles clearly. The second drive in the same server is not a substitute for an off-site backup.
Suitable for administrators with external backups who want to plan separate volumes. Not suitable when two independent drives are expected to provide redundancy.
Usable space varies with formatting and filesystem overhead
