Summary: I was a little disappointed with my read/write speeds until I did a little research. Removing unused protocols and enabling jumbo frames on my adapter (not the NAS, but on my network adapter) yielded nice results.
Pros: You can't beat this NAS at the ~$100 price range. You will have to spend at least 50% more to get better read/write performance. I get write speeds in the 70-75mb/s range consistently, and read speeds in the 80's-90's, in Raid 0.
Summary: Picked this up a few weeks ago from a close-out auction. Expected some basic NAS features and was going to use it to share some drives on my network. Was very pleasantly surprised to find features such as Flickr and Youtube upload support, Dropbox support including a .torrent watch folder. Automated torrent and NZB download support. Media streaming. Extensible through many applications.
Pros: * Lower cost than competition * Basic plug-and-play * A lot of hidden features and applications * Still supported (last firmware update 9/30/13) * Integration with Dropbox, Flickr, Youtube * JBOD, Raid 0, Raid 1 support * Extra USB ports for external drives
Cons: * Hidden features may require technical knowledge * Tablet/Phone web UI is a bit rough around the edges
Summary: I bought it from Amazon a few days ago and I can already tell that this device is a wonderful and cheap (I got a 'used' one) addition to our home's gadgets. We already have a NAS in our home environment (Western Digital World My Book ii ) but that doesn't have a DLNA media server. So I setup a Logitech Media Server on my Windows 7 PC to serve media from the WD NAS drive.
Summary: This is my first NAS for my home, and I read many of thee reviews here before purchasing. I think having a Gigabit speed connection is worth paying extra for in a NAS like this. I'm using WOL to wake it up when I need it, the disks shut down after inactivity, as set in the preferences. Finally, about the time I go to sleep the entire NAS shuts down. I'm happy with the energy consumption and the cooling seems to work very well.
Summary: Ran a benchmarks from my Windows XP64 system with 1gb ethernet Dlink hub, copying 3.8gb ISO file: To external USB 2.0 Fantom 1.5gb drive --> 2:08 To Zyxel NAS --> 2:23 To Zyxel NAS after changing to 4K jumbo frame --> 1:39 My NAS only has 1 drive, a WD WD20EZRX.
Pros: Very fast, low power features, print server (replaces my HP USB JetDirect), expandable via external USB drives, feature rich. Set up in 15 minutes, including formatting my 2GB drive. Take the time to change your network to Gigabyte ethernet and enable jumbo frames the NAS and your PCs for best output.
Cons: Very light weight, seems to be sturdy enough.
Summary: Works great and have had no problems with it so far. It is a little slow when transferring or syncing folders with large amounts of files, pegs the CPU at 100% easily but still works. Once files start copying works pretty good, I am getting an average of 35mb/s to 45mb/s over my network. Edit: Got Working other features I got the WordPress service running and it makes for a pretty nice server for blogging once you figure it out.
Summary: To those that are "Getting about 10-12MB/sec transferring data": This is a limit of your network, you are likely connected using a 100Mb network (still very common in home office networks even most N speed WiFi routers have 100Mb wired LAN) To "fix" this you will need to upgrade your network to include 1Gb routers / switches / hubs.
Pros: Low power consumption Hackable to a point, you can gain root access to SSH and Telnet and really own the box like you should be able to. Able to install other OS to replace the stock setup (requires some extra knowledge) Decent performance from NFS addon module. For NFS from Mac Pro Early 2008 model to NAS I see speeds of: About 35-45MB/s Write RAID0 (striped) - during write I did notice that the CPU was pegged out at 100% so this is the slowdown during write. About 9...
Cons: Could have a faster processor as this seems to be the bottleneck for faster write speeds when using RAID setup. Could have more RAM too not sure if it really needs it though.
Summary: I originally bought a Synology DS112j that I was VERY happy with. I returned it because it's very expensive and only had one drive bay. I bought this one instead for $75 less, and this one has two bays so I can RAID my disks. The Synology has a much cleaner, more intuitive admin console and just looks and feels like better quality.
Pros: Overall, a good value, setup was easy with one gotcha (see below), speed is fine, worth the money.
Cons: Cheap looking and cheap feeling, documentation could be better.
Summary: I didn't try the included software, use the web interface.
Pros: Great features for the price. I needed the RSS downloader and a DLNA server to move from an older Mac Mini over to something headless, and this fit the bill. It's tough to find these features in lower end NAS offerings. The web interface is clean and fast. Handles any size drive I've needed to throw at it and never freezes or gets hung, at least not yet.
Cons: It would be nice if the DLNA server did demuxing (not transcoding) of content, which should be reasonable even with the ARM cpu, but you can't have everything. No eggs off for that.
