Synology products are distributed worldwide and localized in several languages.

 Linux. Hardware components, including CPU type and model, vary across the product range. As with most NAS, emphasis is put on energy, size and reliability. Windows, Mac OS X and Ubuntu clients are supported via common network protocols (SMB/CIFS, FTP, AFP, NFS, WebDAV), using UTF-8 character encoding for compatibility. Native client applications are less notable than the comprehensive AJAX

DiskStation

The DiskStation is a single, dual, quad or five bay enclosure

, slightly larger than the hard drives it contains. DiskStations supports several terabytes of combined storage depending on the model. Higher-end models add features such as Hot-Swap Hard Drives and dual Ethernet connections for fail-over and aggregation.

RackStation

The RackStation is quad-bay 1U or 2U Rack Mount storage server, designed to be installed in a Rack Mount Environment. This higher-priced line offers most features.

USB Station 2

The USB Station 2 is a mini NAS server equipped with the Synology DSM. It does not have hard drive slot but can be connected with an external USB storage device. By accessing the DSM on the USB Station 2, it can then stream and download digital files via DLNA/UPnP support within the LAN and on the Internet. It can also act like a device to share printers.

Expansion Units

Expansion units can be attached to selected DiskStation/RackStation to scale up storage capacity. Depending on the model type, the connection between the main unit and the expansion unit is bonded with either eSATA cable or InfiniBand. eSATA cable offers 3GB/sec connection and InfiniBand provides 12GB/sec throughput.

General Similarities

Except for the USB Station line, most Synology devices have the same features one would expect on a traditional LAMP server: firewall with port forwarding, DDNS, SSL encryption, user/group privilege management, rsync (as client and server), web server, PHP/MySQL, ADS integration, various RAID modes, SNMP, iSCSI targets, mail & print server, power saving and HDD hibernation, UPS-integration, etc.

More esoteric features include file sharing clients for BitTorrent/eMule/NZB, IP camera surveillance, smart-phone integration, Wifi dongles. Differences between models mainly lie in the amount of performance or storage capacities which are required by the user. All products have an Ethernet

 and USB port, while some models feature an eSATA port for connecting external hard drives. Synology NAS units do not ship with hard drives by default; instead customers are presented a list of recommended models/brands they'd purchase separately.

Most models allow chain-linking to increase storage space and performance.

Community Interaction and Contribution

Synology stands out by openly embracing its power-user/programmer enthusiast community. Hundreds of ported and original applications have complemented Synology's own catalog over time.

 available.

Third-party applications are either written in an interpreted programming language such as PHP—hence run on all models despite hardware differences—or compiled to binary format. Such native applications are fairly easy to find despite the numerous different CPUs used by Synology products. Public APIs let custom applications fit seamlessly into Synology's own web-based user interface. Installers using the SPK format can be installed from the web UI itself.

Synology's built-in firmware is updated relatively frequently with new features, even for older models, a practice arguably at odds with the usual business model of Planned Obsolescence

through software/hardware binding in order to push new model sales.

Oddity

While source code is publicly available, Synology is opaque about models' CPU type. They are not listed in their otherwise extensive specifications and when randomly found in PDF product briefs come with a fine-print that specifications may change at any time. Although this gives them freedom to negotiate with hardware component suppliers, volatile hardware specifications are at odds with their general openness—and a risk to customers since closed-source binaries may only be available on certain architectures (e.g. virtual machines or source control).

Note that this info can be found on the official Synology Wiki since 6 April 2008.
