Notes
- Usable capacity for each volume will be lower than the maximum volume size and is dependent on the filesystem and the amount of system metadata stored.
- Actual maximum storage pool and volume sizes depend on drive sizes used, the number of drive bays available, and the RAID configuration.

Notes
- Performance figures are obtained from testing conducted with the device fully populated with drives, with their default memory configuration, and under a continuous recording setup. Actual system capabilities may vary based on configuration, drive performance, enabled features, and the presence of additional workloads.
- Use NVR Selector to quickly find a suitable model based on your requirements.
- The maximum number of camera stream outputs is 2 times the suggested maximum number of IP cameras.
Recommended Number of Concurrent Sync Clients200 (the number of connections that can be maintained when the recommended number of hosted files was reached) Recommended Number of Hosted Files500,000 (applies to files indexed or hosted by Synology Drive. For file access through other standard protocols, refer to the File Services section above) Notes
- Exceeding the recommended numbers above will not block application operations, but may result in longer response time.
- Btrfs file system and non-encrypted shared folders were used during the aforementioned testing.
Suggested Maximum Users500 Suggested Concurrent Users200 Notes
- Multiple files were opened for testing and each file was edited by 30 users simultaneously.
- Client performance may affect maximum simultaneous editing users. Client PCs used for testing: Intel Core i3-3220 / 8GB RAM
