Notes #8 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 number of video channels that can be viewed simultaneously is double the maximum number of cameras for the same codec and resolution.The values above are based on testing with RTSP streaming. If SRTP is enabled for all cameras, overall performance will decrease to 70% of the stated figures.
Synology Drive > Maximum Number of Users 5
Maximum Number of Hosted Files 100,000 (applies to files indexed or hosted by Synology Drive. For file access through other standard protocols, refer to the File Services section above)
Notes #9 The suggested maximum number of users is based on the following workload: 20% of users randomly perform file operations (upload, download, move, and delete), and 80% of users are logged in but idle. Learn moreModels with SSD support are tested with a single SSD volume.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.
Synology Office > Maximum Number of Users 5
Notes #10 The suggested maximum number of users is based on the following workload: 20% of users are executing random actions at an average of 30-second intervals, and 80% of users are logged in and viewing a file.
