NAS devices comes in all shapes and sizes, and there's lots of choice. But when you want to use more disks you quickly end up looking at rack-mounted models. These are generally large and heavy and loud, so not so great for office environments. Last year we looked at the Synology Disk Station DS2411+, a NAS with room for 12 disks in a compact, cuboid chassis. Its replacement has now arrived in the form of the Disk Station DS2413+.
From the outside it looks identical to last year's model. It's a compact cabinet with space for 12 disks in individual trays that fit both 2.5-inch and 3.5-inch disks. The lock above the trays allows you to lock them in place. The front also has a power button and control LEDs that indicate the activity, which network ports are in use, and whether there is a problem. Simple yet effective.
The back side is fairly modest as well, with two gigabit network ports, four USB 2.0 ports and two USB 3.0 ports. Those last two are extras if you compare it to the DS2411+. There is also a serial port, but no monitor connector that last year's model had. It does have the special connector for adding the DX513 expansion unit with space for five extra disks or the DX1213 with room for 12 disks. The latter is the reason for the "24" in the name of the Disk Station DS2413+. 12 disks in the NAS itself plus the 12 extra disks equal 24.
