Summary: Very good experience with this unit and with the company. The first one that arrived didn't want to talk over Ethernet. Zyxel tech support walked me through troubleshooting including a couple of ideas that hadn't occurred to me. When all failed, they agreed to replace the unit.
Summary: Very happy with this little box. Put a couple of SATA drives in that I had, plugged in an old Maxtor 1gB USB drive and installed the included software. Used primarily as a media server, I will probably buy another one to serve as a backup to my network PCs.
Summary: For its price it's the best NAS you can ever find. I never tried any NAS more expensive than 200 bucks and all of them were... well. The truth is that all of them were piece of sh*t. With only exception of Zyxel NSA320. It's true that it's not straightforward to configure it for the first time.
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).
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.
Summary: I have a ZFS Nas4Free raid box and this in some ways is better. For streaming media this is easier to use, when you copy a file to the movies folder its automatically updated ready to be viewed on a smart TV.
Summary: I've had this for over a year now and it's been running 24/7 non-stop ever since. Never missed a beat, with 2 x 4TB drives it hums away under the bench never complaining, and transfers my nightly backups quickly without incident.
Summary: I recommend using raw drives for initial install especially if you are having a problem. I have a few of these for quite a while and they are all good. I use Hitachi 4TB drives with good success. There is a new version the NSA 325 v2.
Pros: Fastest read / write in it's price range. Easy to set up and get running. Great for home media server and general back up storage. By the way, try deleting any Volumes / partitions and start with a raw drive.
Cons: Hard drive install and removal could be better. Other manufacturers are able to get the drives in and out without adding caddies or using a handle / pull tool for removal.
