Summary: After having spent lots of quality time with the N5550 NAS, my thoughts about it are mixed. It was very reliable and performed well during all testing, registering high enough network transfer speeds. I also liked the fact that Thecus provides the option to skip disk check during RAID creation since it curtails RAID creation times significantly.
Pros: High price/performance ratio, Support for five hot-swap disks, Highly reliable operation, Low power consumption, Strong PSU (200 W) with 80 Plus certification, Comes with 2 GB RAM installed while most of the competition only has 1 GB, Fully metallic casing, Very high build quality, Lots of features, HDMI, VGA, and audio out ports, Supports all popular RAID levels, Dual Gigabit ports (with LACP support), Option for fast RAID creation, Front USB 3.0 port (though covered...
Cons: The operating system's interface isn't as appealing and intuitive as the competition's offerings, Installing available modules can be really tricky, High memory utilization, especially during heavy network throughput, Fan can be noisy, No fan profile adjustment via software possible, Any change to the Networking Section (and not only) demands for a lengthy reboot, No option to format an external drive, The trays aren't numbered, Long reboot time (100 seconds), Limited...
Thecus N5550 - a Fast and Relatively Inexpensive 5-bay NAS
27 March 2013
Summary: We next might want to have a look at one of the top-of-the-line units from Thecus, like the N16000, as we have reviewed similar rackmounted units from our other friends in Taipei (see our many QNAP and Synology rackmounted NAS reviews). That will tell us whether there are any significant performance and price differences on the high end of business.
Conclusion: The Thecus N5550 is one of the most feature packed and capable five-bay NAS solutions currently available for under £450. Armed with a dual-core Intel Atom processor and 2GB of DDR3 memory, the N5550 consistently serves up data transfer speeds close to 100MB/s, and it has a feature set that easily encompasses the needs of both home and office users.
Summary: The most important factor to consider with the Thecus N5550 is the price and that really goes for any product. However in the case of the N5550 it’s rather cheap for a 5-bay NAS with a retail price of just $510. As we mentioned earlier in comparison the Drobo 5N costs $600, the QNAP TS-569L $750 and the Synology DS1512+ a whopping $840.
Excerpt: The unit’s CPU is a 32nm, 64-bit dual-core processor with hyperthreading support running at 1.86GHz. With a 10W TDP on the Cedar Trail platform, we can expect the N5550 to offer great performance while keeping the power consumption quite low.
Pros: Good sequential read and write performance, Runs very cool, HDMI port for HD content streaming, USB 3.0 support, Dual network, Easy to navigate interface, ISO mount, Mini-UPS support
Cons: No automatic firmware update, No dedicated disk copy button, Front LED display is hard to navigate, Single USB 3.0 Port, Backlighting on LCD can be distracting and not disabled
Conclusion: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. As Albert Einstein said, " Not everything that can be counted counts, and not everything that counts can be counted.
Pros: Very high transfer speeds, Local Display capability on VGA, HDMI, Excellent value, High quality construction, 2GB SDRAM is standard, USB 3.0 port on front panel, McAfee Anti-Virus S/W included, Acronis Backup S/W included, Quiet operation, Integrated 200W power supply, All the usual support apps available, Active Company and Community support
Cons: Can't migrate from single disk to RAID volume, USB 3.0 port is hidden behind front door, Must be on same sub-net as workstation, or use static IPs, Adhesive on feet came loose, Drive trays and bays not labeled 1,2,3,4,5
Do much more than just store data with this 5-bay network-attached storage device

Summary: There is plenty to like about the Thecus N5550. It has five drive bays yet it doesn't cost the Earth, and it can be almost endlessly configured via extra modules from Thecus and third parties. However, it's a device that does require a fair bit of tinkering so only consider it if you don't mind getting your hands dirty.
Pros: Five drive bays, Well priced, Stacks of features to play with
Cons: Needs clearer and more in-depth documentation, Build quality doesn't feel great
Excerpt: The Thecus N5550 is a standalone NAS enclosure with an Intel Atom D2550 processor, 2GB of RAM and the capacity to take up to five hard disks, which means it'll support RAID5 arrays with a hot spare, a feature lacking from many smaller NAS devices. It has a mono LCD status screen at the bottom that displays errors, the NAS's IP address and other useful information.
