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...
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
