Synology Disk Station DS710+ is a dual-bay NAS server, much like the Editors' Choice winner DS209+, with one major difference: its storage is scalable to up to seven bays. Other than that, the DS710+ shares very much the same set of features with the DS209+.
The server performed excellently in our tests, and we loved its robust Web interface that helps users navigate through its large amount of features and functions. The server's few shortcomings include the fact that it supports only one IP camera out of the box and requires more licenses for additional cameras; its lack of dual Ethernet option that would help maintain the high-throughput even during heavy loads. Finally its storage scalability isn't practical.
If you're looking for an advanced NAS server that offer all you might expect from a product of its type, for around $570 (no storage included) or around $860 (with 2TB), the Disk Station DS710+ will make a good investment. If you want something similar that can support two IP cameras out of the box and has dual Ethernet, we'd recommend the QNAP TS259 Pro .
Design and setup
The Disk Station DS710+ is Synology's first 3.5-inch hard drive-based NAS server that offers easy access to its storage. Unlike the DS209+, which requires you to open the device's cover to access the hard drives, the DS710+'s two drive bays are easily accessible from the back. This makes installing and replacing the hard drives a much quicker task.
The server can work alone as a dual-bay NAS or couple with the DX510 expansion enclosure unit, which costs another $500, to support up to seven hard drives. The DX510 isn't available as of this review posting, but according to Synology, it'll be connected to the DS710+ via its eSATA port on the back. Add to that the fact that the DX510 is about 2.5 times the size of the DS710+--regardless how many hard drives it contains--and the solution starts to seem more clunky than practical. It would be better if somehow the server could accept more hard drives and still remain a single unit. We believe the DS710+ would work best just by itself as a dual-bay NAS server.
Apart from the eSATA port, the Disk Station DS710+ also comes with three USB ports, two on the back and one on the front. These ports can be used to host more external storage devices or printers. The front USB port can also be used to quickly back up the entire contents of a USB storage device, such as a thumb drive. This is a popular feature found in many new NAS servers.
The Disk Station DS710+ ships both with and without storage. Our review unit comes with two 1TB hard drives that can be set up in either RAID 0 or RAID 1 configuration. When coupled with the DX510, Synology claims, the DS710+ can support other RAID configurations, including Synology's proprietary Hybrid RAID, which allows the use of hard drives of different capacities.
Like other NAS servers from Synology, the DS710+ won't pose any problem for savvy users when it comes to setup. Not so much for home users. The NAS server comes with a desktop application called "Synology Assistant" to help users with the initial setup. Apart from detecting the NAS and launching the Web interface, the software doesn't provide enough information on what it does and may seem confusing and intimidating for those with little computer knowledge.
Nonetheless, we had no problem getting the server up and running. In our trial, the server took only about 30 minutes to switch from one RAID configuration to another. This is significantly shorter than most NAS servers that take hours to get the same job done. This is because the DS710+ allows you to skip the hard-drive check during a RAID build. This reduces the build time, but would pose potential problem if the hard drives contain bad sectors. When a disk check was included, the DS710+'s RAID build time took about as long as any other NAS servers.
Unlike the desktop setup application, the server's Web interface is one of the best. Once launched via a Web browser, all features and functions of the DS710+ are listed in a well-organized menu on the left of the interface. Most of the setup sections are wizard-based and walk you through step by step. For example, when we clicked on "Share Folder" and then clicked "Create," a wizard launched to walk us through all the steps involved in making a new share folder and assigning user access to that folder.
Running Synology Disk Station Manager 2.2 firmware, the DS710+ shares a similar feature set to most other NAS servers from Synology that we've reviewed, such as the DS209+ or the DS410Slim. The NAS server has all the basic features you'd find in any NAS server, such as FTP/HTTP server, media streaming servers, user account, and support for external hard drives and printer.
On top of that, the DS710+ also has advanced features, including support for Windows Active Directory Services, which allows it to work seamlessly with a centralized domain server. It also supports iSCSI, which allows you to facilitate data transfers and manage the storage over long distances through the network. The server also offers excellent support for file sharing across multiple platforms including Windows, Mac, and Linux. It also has support for Apple's Time Machine backup solution in addition to many other features. However, what we like the most about the DS710+ are its application stations, including Surveillance Station, Download Station, File Station, and Photo Station. All of these stations can be accessed via the local network or over the Internet.
The DS710+'s Surveillance Station supports up to 16 IP cameras. Unfortunately, only one camera license is included and for additional camera licenses, you'll have to pay $49 per license. Of all NAS servers that have support for IP cameras, Synology NAS servers, including the DS710+, have the most comprehensive surveillance features. You can view live images and record them based on scheduling or motion detection. When multiple cameras are used, you can even synchronize the playback to see what happens on different cameras at a given time. The server supports a long list of the IP cameras on the market and is able to detect those connected to the local network to help facilitate the setup process. We tried the server out with an Axis 213 PTZ and a Panasonic BL-C1A IP cameras and were very happy with the results. So far, among NAS servers, Synology has been offering the best solution when it comes to surveillance. We wish, however, that this feature didn't require additional licenses purchases to support multiple cameras.
