Notes #21 Volumes over 108 TB require 32 GB of memory or more.Actual maximum storage pool and volume sizes depend on drive sizes used, the number of drive bays available, and the RAID configuration.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.Storage efficiency helps reduce storage space consumption through deduplication and compression. For more information about this feature and its support requirements, please refer to this article. | Actual maximum storage pool and volume sizes depend on drive sizes used, the number of drive bays available, and the RAID configuration.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.Storage efficiency helps reduce storage space consumption through deduplication and compression.

Notes #27 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. | 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.
