Thecus N5550 NAS
If the N5550 looks familiar, that's because Thecus used the same case for a few other products as well. When we reviewed the N5500 in 2009 we found it to be an amazing NAS with best in class performance. The N5550 looks nearly identical on the outside, but has new 2012 features.
The front door hides the drive bays and makes the N5550 appealing for home users. Beyond the door we found the five drive bays, power and reset buttons. The N5550 also has a row of status LEDs along the top just about the single USB 3.0 port on the front.
At the bottom, Thecus has a status display panel with manual settings adjustments for some of the most used settings.
The N5550 can only use SATA drives; the backplane is not keyed for SAS connectors.
The side with a motherboard under the cover has an open vent to cool the components.
The opposite side appears open, but it's covered with a film on the inside.
The N5550 uses a large fan to cool the HDDs and the power supply has a fan as well. The system is quiet and you can use it on your desk if you need to have it close by your work space.
The internal power supply means you don't have to worry about an external power brick.
The N5550 has a microphone and line level input as well as line level output on the back. An eSATA connector is next two four USB 2.0 ports.
We've seen VGA connectors on NAS servers for years, but HDMI capability is new for 2012.
Dual gigabit Ethernet ports bridge the gap between a typical home NAS to a more powerful small business unit.
The cover comes off very easy with preinstalled thumb screws so you can easily upgrade the RAM inside the NAS.
Inside we found a single DOM and this nice little add on that's undocumented. It's an mSATA slot. This has me wondering if a Windows Home Server unit wasn't on the drawing board at some time.
The N5550 ships with 2GB of DDR3 RAM. This is twice what many of Thecus' competitors' uses in similarly priced units.
