Zyxel NSA-220 NAS review: Zyxel NSA-220 NAS

Features
The best feature of the NAS-220 is its Web interface. Like most NAS servers and networking products, the NAS-220 lets users access its control panel via a Web browser. Most Web interfaces are static and require a lot of user inputs, but this is not the case with the NAS-220. The device's Web management application is rich, intuitive, and works very much like a desktop application.

Thanks to this, the NSA-220 offers an easy and clear way to manage shared folders and user accounts. You can make a shared folder public, where it can be accessed by anyone in the network, or make it private, where you can set a user's specific right to it including: no access, read-only, or read-write access.

Like other NAS servers, the NSA-220 offers popular network storage features including FTP server, media server, iTunes server, PC-less download service, and print serving. We tried these out and they worked as intended. The download service lets you download files directly to the NAS server without having to use a computer, which helps save energy, frees up your computer for other tasks, or can just be used for a long download--such as downloading a video overnight. In addition, the NAS also has an interesting feature called "broadcatching" that automatically keeps tab of RSS feeds such as podcasts or news. We tried the feed for the Inside CNET Labs podcast and were impressed by how well it worked. We could, very conveniently, set this up, download all the episodes at once, put them in designated folder, and make them available to other PCs via the iTunes and media servers.

On the other hand, the NSA-220's over-the-Internet access is rather hard to set up and was limited. We had to manually change the settings of the router to make this work, which include mapping the IP of the NAS server and forwarding the port to that IP. The NSA-220 doesn't have a special way to host photos or media files, like the Photo Station feature found in the Synology DS-107+.

Performance
We tested the NSA-220 in all the hard-drive configurations it offers, including JBOD, RAID 0, and RAID 1. Other than the sluggish RAID 1 that registered only 34.3Mbps and 35.2Mbps on CNET Labs' write and read tests, respectively, the NSA-220 did above average in the rest of our throughput testing.

In RAID 0 configuration, which is optimized for speed, it scored 49.5Mbps on our write test and 41Mbps on our read test. By comparison, these were significantly faster than the similarly configured VOX V1, while at the same time noticeably slower than Thecus N3200. In JBOD configuration, the NSA-220 scored slightly slower at 47.8Mbps and 39.4Mbps on our write and read tests, respectively.
