4.0 out of 5 starsA nice media server that does many things right!
By Tom Servo on June 6, 2012
Size: High-performance 2-bay Verified Purchase
Reviewed: Zyxel NSA325. It supports 2 x 3.5" SATA drives, has 2 USB2 ports (back) and a single USB3 (front) & has Gigabit Ethernet. 1.6GHz Marvell processor is faster than older NAS devices (faster than the 800MHz CPU in the D-LINK DNS-320 or the 1.2GHz CPU in the DNS-325) and 512MB memory allows multiple functions at same time.
DRIVE INSTALLATION:
Drive guide rails must be attached to each drive via screws. Note that the pointy end of the rails must face INWARD (i.e. on the same side as the SATA connector). The quick install sheet doesn't mention this and it's easy to overlook from the diagram. The reason for the specific orientation is that you use a tool (located behind the drive cover) to remove an installed drive from its bay and this tool clips onto the exposed end of the drive rails. Also when installing be sure to insert the drive so that the SATA connector will mate with the drive (it will not if you insert the drive the wrong way and you could cause damage). ZyXEL needs to have better instructions. The front door is a little flimsy though, be careful when removing/installing to avoid breaking the tabs that keep it in place.
Note that drives are NOT hot-swappable, do not remove/insert with the power on. Drives up to 3TB are supported with newest firmware (note if you have old firmware you will need to temporarily install a smaller drive, create a volume, then use the firmware check function in the web interface to update firmware before installing 3TB drives).
RAID:
RAID 0/1 are supported. RAID 0 uses the combined storage space of both drives but has no redundancy. RAID 1 mirrors contents on both drives so if one fails your data is still safe.Read more ›

4.0 out of 5 starsNot perfect, but still pretty good in this price class
By Patrick Deno on November 2, 2012
Size: High-performance 2-bay Verified Purchase
After a few days of tinkering with it, finding, researching and resolving a few minor issues (mostly of my own making), I can say it's not a bad little piece of kit. There just needs to be better documentation on some of the more common problems that can show up. Remember, G**gle is your friend.

Unboxing: When the package with this little unit and my two drives came in the mail I was very excited. The Amazon package was relatively large and bulky, but when I opened it up and began pulling everything out - first the packing pillows, then the two hard drives, and finally the appliance, itself - and began unwrapping it, I was amazed at how small this little unit is. For what all it can do, I was actually expecting something twice its actual size. This thing's tiny! It's positively adorable! But, although it's clad in plastic, it doesn't feel insubstantial or fragile like a toy. It has some weight to it, especially once you install the drives. You could actually club someone with it and do a fair amount of damage, though you'd probably break the housing in the attempt. With the little rubber feet it sits sturdily on just about any surface.

Setup: I ordered two Seagate Barracuda 7200 3 TB 7200RPM SATA 6 Gb/s NCQ 64MB Cache 3.5-Inch Internal Bare Drives (ST3000DM001) to go with the unit and they work great. Jump on these while they're still relatively cheap and you'll be a happy camper. I mounted the rails on with no problems, slid the drives into place in the housing and turned on the unit. I gave it time to boot - yes, the one reviewer is correct, it does take a bit of time for it to do so, about 2 minutes or so - and then installed the included NSU software.Read more ›

5.0 out of 5 starsGreat little box
By Amazon Customer on January 21, 2013
Size: 1-bay Verified Purchase
The ZyXEL NAS310 is a nice little package, But I think it takes a little reading of the Users' Guide to come to grips with how it is best used. Especially if this is your first taste of a modern NAS. The Guide, a nearly 600 page PDF included on the CD that comes in the box, sounds intimidating as all get out ("600 pages, Oh My!") but is easily skimmed and the table of contents and index can usually point you in the right direction quickly..

I was looking for something that would be faster than my old USB-ethernet device that published a couple USB drives to my LAN, but was pretty slow. This ZyXEL gadget does the trick.

I keep the data files for a couple applications on the network so I can access them from different computers running the same software. And this works much better with the ZyXEL (except when the internal HDD has to "wake up" then there's maybe 5-10 seconds lag while it spins up). You can adjust the HDD sleep time from the std 15 minutes of no activity.

I also wanted to be able to plug in an external drive (USB or eSATA) and have that drive usable on the LAN. Specifically, I have two clients for whom I do some work and want to be able to give each it's own HDD and to be able to add them or delete them from the LAN when appropriate. The NAS310 has an eSATA and a pair of USB 2.0 ports that can be used for just that. But it was not clear to me how this worked.

So I called their tech support before buying and asked, But I was told it couldn't work like that...the disc contents would become part of the larger data container. To me that sounded like the contents of the external drive would be shared out with the internal drive. And that almost unsold me. But some snooping on ZyXEL's user forum revealed how this worked...Read more ›

This NAS enclosure is not considered as a high-end one, but it's fast enough for up to 10 concurrent Users accessing the NAS. Very cost effective too.
