Synology is a corporation that specializes in Network-attached storage appliances. Synology’s line of NAS is known as the DiskStation for desktop models, FlashStation for all-flash models, and RackStation for rack-mount models.
The Synology DiskStation is the network attached storage (NAS) appliance which is produced to run the Synology DSM OS. The DiskStation is a pedestal/tower embedded NAS appliance, which ranges from one bay to as many as twelve bays within a single enclosure. Some models feature storage scalability, where physical units may be tethered together for additional storage, without the need for volume recreation or loss of availability
The Synology FlashStation is an all-flash version of the DiskStation.
The Synology RackStation is a rack-mounted version of the DiskStation. It features all of the same abilities of the DiskStation with the exception that it is meant to be enclosed in a 19-inch rack cage. Some of Synology’s rack models feature redundant power supplies. As with its desktop-oriented brethren, select models of the RackStation also feature storage scalability.
