Summary: This thing Rocks! After my Net gear Stora died. I tried another brand. Unfortunately it was junk. The ZyXEL is amazing. The software is easy to setup and navigate. It is also very fast, compared to my old Stora (keep in mind I'm using the same 1T drives I had in the Stora). I have had this running for approximately two weeks with no issues. If your looking for a Network Attached Storage on a budget this it the one to buy.
Summary: I had a Western Digital My World Book which all of a sudden started going off-line. I decided to replace it and after doing all the reviews the ZyXEL seemed like a good choice. I moved my drives over from the WD and they worked fine even though they were not on the compatibility list. The comments about a useless manual are correct. It took me a bit to even figure out how to open the NAS to put the drives in.
Summary: This is a great NAS. I use it with XBMC via gigabit and wireless, and it hasn't failed me. I haven't tried it with multiple instances of XBMC, but I would probably recommend only one instance at a time, unless RAID 1 is in use. The beauty of this gem is the fact that you can gain admin privileges over the NAS with the installation of FFP (google it). From there, you can technically SSH the machine and use various linux applications.
NSA320 is the best price/performance NAS I could find

Summary: First, the most important piece of info - After being slightly disappointed with write speeds in the high 30's, I started researching tweaks and found two very fruitful suggestions: Go into your computer's network adapter settings, and 1) Turn off the protocols that you aren't using (in my case, IPv6 and QoS packet scheduler and others), and 2) Enable jumbo frames on your NIC (mine was defaulted to disabled, so turning this on for the NAS wasn't enough).
Good Product for the money. Highly recommend but be careful of config

Summary: This product has a lot of value for the little price that you pay for it. I stream a lot of movies that I get from various places and also store files and music on this device. Have a total for 4TB installed on this device as JBOD and after initialization (can take quite some time so don't be in a hurry, also will wipe contents of drive so back-up before installing). Once it's up and running configuration is done via web interface and has lots of bells and whistles.
Summary: I bought this right after Christmas as a backup to my primary NAS. I set it up and all worked. A week later I was going to configure it some more and it would not respond. It looks like the NIC stopped working. Tried a few things but no luck. I just wanted another one but they only do refunds, not replacement. So far so good, no hassle but I need another one. Still might give this model another chance but have not decided for sure yet.
Summary: I recently bought one of these refurbished and was very pleased. I then bought a new one for my Accounting firm to back up all our tax files but it showed up DOA. Apparently a whole lot of these have firmware issues that keep them from booting correctly. Watch out.... Buy refurbs, they have the fixed firmware.
