“The ‘Express Replacement’ service is an initiative by Synology and its authorized distributors, allowing Synology partners to provide customers with a replacement device without long downtime in the event of a failure.
Thanks to local stock with replacement units and spare parts, the partner should receive a replacement device within a maximum of 3 days*.
 
*The service is free of charge.
*The replacement time is not guaranteed, as it depends on the current availability of replacement units and spare parts. Therefore, in some cases, the replacement time may be extended.”
