The SSD Tax
High-performance NVMe storage is expensive. Don't pay for 1TB if you only need 100GB. However, remember that many filesystems (like XFS or EXT4) become significantly slower when they reach 90% utilization. Always aim for a 20% "free space" buffer.
Backup Math
A typical rotation of 7 daily and 4 weekly backups can multiply your storage needs by 3x or 4x. Use deduplication or incremental backup tools (like Restic or Borg) to reduce this overhead on your raw disk space.
