Configuration
Calculations assume 100% bus utilization efficiency. Real-world performance may vary based on NVMe controller overhead and OS file system overhead.
Why Bandwidth Isn't All
Bandwidth determines how fast a large single file moves. However, IOPS (Input/Output Operations Per Second) is the true king for OS responsiveness, gaming, and application loading speeds.
