Notes:

Compared with its predecessor, the Synology DiskStation DS220+. Performance figures are obtained through internal testing by Synology. Actual performance may vary depending on the testing environment, usage, and configuration. See performance charts for more information.
C2 Storage for Hyper Backup and Hybrid Share requires purchase of an eligible annual or monthly subscription. A free trial is available for each newly registered Synology Account. Learn more
Surveillance Station includes 2 free licenses. Connecting more cameras and devices requires additional licenses.
Storage drives are sold separately. Refer to the compatibility list for compatible devices.
Extended Warranty Plus must be purchased within 90 days of the device purchase date, or if none is available, 180 days of the device manufacturing date. A Synology Account is required for the purchase. The starting date of the Extended Warranty Plus additional coverage is calculated based on the purchase date of your Synology NAS. If you cannot provide proof of purchase, the device manufacturing date applies.
Express shipping is a paid add-on available in select countries only.

Notes:

Model specifications are subject to change without prior notice.
The figures are based on Synology internal testing. Each performance test is done individually. No other services or applications are processed at the same time.
The actual performance may be lower than lab testing figure due to differences in server configuration, deployment, and the number of active operations.
If usage requirements exceed the specifications above, please contact our regional partners for professional advice.
