Synology NAS devices are very popular, and with good reason. They generally perform really well, and have lots of features, but their main drawback is always their price. In this review we will take a closer look at the DS413, a NAS which is similar to the DS213+, except that it can fit four disks instead of two.
The hardware inside the DS213/DS413 is quite interesting. Most NAS devices run on processors with ARM cores, and high-end models often have Intel processors, but Synology use chips from FreeScale. It's a Freescale 1,067 GHz P1022 dual-processor, based on the Power architecture. The NAS has 1 GB DDR3 of RAM, twice the amount of the DS-213+. This model also features hardware-accelerated encryption, thanks to the FreeScale chip.
The exterior looks a lot like the more deluxe models from Synology, much more so than the entry-level DS413J. The four disks sit in individual, easy-to-remove trays. They're hidden behind a front panel that's attached with rubber feet to the casing. It's very easy to access the disks.
The gigabit network port is located on the back, along with an eSATA port and two USB 3.0 ports. The front has a USB 2.0. Cooling is provided by two silent fans in the back of the chassis, and power comes from an external power supply.
When the NAS is idling and the disks are inactive, it only uses 0.8 watts. When everything is active is uses almost 40 watts. The DS413 stays really quiet, even with the two fans running.
