SYNOLOGY DS223J 2BAY NAS

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.

Connection value of this model is tested with Synology SATA HDD fully populated and all onboard network ports.

SMB performance was evaluated using Microsoft File Server Capacity Tool (FSCT) version 1.3, with the following configuration:

Test workload: HomeFolder scenario provided by the FSCT tool

Test duration: 600 seconds

Domain controller & FSCT controller: Windows Server 2022

FSCT clients: 8 × Windows 10 machines

SMB feature: Directory leasing enabled

1080p: 12 channels, 360 FPS

3M: 12 channels, 300 FPS

5M: 12 channels, 150 FPS

4K: 11 channels, 110 FPS

1080p: 12 channels, 360 FPS

3M: 12 channels, 360 FPS

5M: 12 channels, 350 FPS

4K: 12 channels, 200 FPS

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.

The number of video channels that can be viewed simultaneously is double the maximum number of cameras for the same codec and resolution.

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 more

Models 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.

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. Learn more
