So far I was considering only 2-Bay Synology or QNAP as my first home NAS. There wasn't much of a competition. But recently it is Synology vs QNAP vs ZyXEL NSA325. From latest review it looks that Zyxel has good performance but at lower price than i.e Synology. Where is a pitfall I haven't noticed?
Try before you buy, via their web site. If they have it.
ZyXel is a good company for SOHO network devices.
Be sure their NAS operating system, features and applications, and stability are on par. I very much doubt it. Doing NASes well is hard, and that's why Synology/QNAP/Thecus limit themselves to that. So Netgear, Buffalo, IoMega and others are not on par, as I see it.
Both Craig and I were impressed with the ZyXEL's feature set and the array of installable add-ins.
As with all products, we can't speak for long-term reliability. But the NSA325 seems to have lots of bang for the buck and a decent admin GUI.
Part of the reason QNAP, Synology, NETGEAR are priced so high is that people have been willing to pay for the extra features. Iomega, WD, ZyXEL are finally waking up and starting to put up more of a fight by adding features. Buffalo, unfortunately, has not kept up with the competition in either features or performance.
I own NSA325 no issues with it at all. For NAS wise it works like they have describe it. It's also a Print Server I use with my DELL Color Laser 1250c, Media Server works with both Toshiba Thrive 10.1 Android Ice Cream Tablets where I can stream movies from it to any media network device wired or wireless. There is also Web Server I use that now instead of IIS7. FTP Server too. Can use Cloud Servers like Dropbox too with it. Can be access via Internet using their Android app to remote control your NSA325. Lots a features for a device that can support dual 3TB for 6TB. 1.6GHz and 512MB with Gig Port, USB3 and 2x USB2 ports.
I think people might also want to consider the NSA320, another two-bay Kirkwood based NAS from ZyXEL. The main differences, near as I can tell:
1.2 GHz CPU vs 1.8GHz
3x USB2 vs 1x USB3 and 2x USB2
~$110 vs ~$170
Firmware features and UI seem similar, if not identical. The NSA320 also has 512 MB RAM, and installable packages. Both run Linux, and support hooks for "fun_plug" that allow you to run scripts off a USB drive at bootup, which provides an avenue for installing 3rd party software.
I picked mine up for $90, and ended up installing Debian on it. I'm thinking of popping for another. It's not the fastest hardware, but its good enough for my needs, and the low price, relatively plentiful RAM, and compact, quiet enclosure are nice.
Streaming from NAS to things in your home - uses only you local area network (LAN); no routing needed. Indeed, if you get a 10/100/1000 ethernet switch, connect to it your NAS, router LAN port, PCs that are wired, game consoles, etc., then none of the data even goes to the router, unless it's generic internet traffic.
