Is M.2 NVMe caching worth it?
Yes, caching can significantly improve performance for your 4K video editing tasks, especially if your workflow involves frequent access to smaller, random files (e.g., project files, assets, or software cache). With NVMe read/write caching, your system will access frequently used files more quickly, reducing latency and improving responsiveness during editing sessions.
Optimum NVMe Cache Size:
For your 80TB storage pool, a 1TB NVMe drive is a practical choice, as Synology typically recommends 1GB of cache per 1TB of storage for balanced performance. Larger capacities provide additional headroom for intensive workloads, but this depends on your budget.
Alternative Option: Use NVMe for Storage
To take performance a step further, you could create a dedicated NVMe storage volume for live editing projects. This approach allows you to benefit from the full speed of the NVMe drives without the caching layer. For optimal results:
Add two M.2 NVMe drives in RAID 1 for redundancy (if data safety is a concern).
Use this volume exclusively for active projects and transfer completed files back to your main RAID 5 pool.
Additional Considerations:
Ensure compatibility with Synology’s recommended NVMe models to avoid issues. Popular options like the Samsung 970 EVO Plus or WD Black SN850 are excellent choices.
For even better performance, consider scaling up your direct network speed if possible (e.g., leveraging multiple 10GbE links).
Impact on Plex Streaming:
For Plex, NVMe caching has minimal benefits, as video streaming is typically sequential and does not rely on caching mechanisms for efficiency.
