Synology again managed to impress me with their product. The DS713+ is a real speed demon as i saw up to 200 MB/s read and 138 MB/s write once I combined its Ethernet NICs. The NAS operated flawlessly even with five clients asking for huge data throughput, and its CPU easily coped with the task. The dual-core Atom may be weak in a normal desktop systems running Windows, but it is just fine for a NAS running a custom-tailored Linux OS, even with multiple clients. The DS713+ only takes two HDDs out of the box but its capacity can be expanded upon to support up to seven disks with the Synolog DX513, so acquire only the NAS at first to then invest in the DX513, or the smaller DX213, to upgrade its capacity. But the stronger feature of this NAS, and of all Synology products in general, is the awesome DSM OS they run. DSM is really fun and easy to use, and provides tons of features. Its optimal application packages also boost the server's functionality, allowing user to completely optimize the NAS around their needs. For those concerned about security matters, the DS713+'s strong hardware allows it to support up to 20 IP cameras, and the Surveillance application package provides many surveillance options to the user. The only problem is that only the first license is free, so you will have to purchase multiple licenses if you want to install multiple IP cameras, but that is the case with products by the competition as well—Asustor, being the exception, provides four licenses for free. The only significant downsides of the DS713+ are its unnumbered trays—I really wonder when they will fix this—, the fact that you cannot format attached external storage disks to NTFS, and that the RAM can't be upgraded easily, since there is only one slot and cracking open the NAS is a daunting task. However, 1 GB will suffice most of the time. This is, after all, a NAS and not a gaming station.

To sum up, the DS713+ offers great performance and reliability, and comes with a massive list of features. Considering its capabilities and the time and money Synology spent on developing its software, it is, on top of that, sold for a fair price. You also shouldn't forget the very important support Synology offers with their products, and Synology provides the DS713+ with a three year warranty instead of the two years of the competition, which is a big plus. The DS713+ is a great choice if you need a strong NAS with the option to upgrade its storage capacity later on.
