The ReadyNAS Duo is perfect for homes with more than one computer. Unlike a USB drive, the ReadyNAS connects to the network and is simultaneously accessible via all connected Windows or Macintosh computers. If there is a broadband Internet connection and a home router, the ReadyNAS can be set up to provide secure access to all the stored files remotely via the Internet. For added protection of stored data, an optional second Hard Drive can be installed. The spare hard drive will keep an extra copy of all the data and instantly take over if the first hard drive should fail. Advanced media streaming support allows the ReadyNAS to directly serve media, with no PC required, to devices such as the NETGEAR EVA8000, Sonos Digital Music System, Logitech Squeezebox, Apple iTunes clients, Sony Playstation 3 and Microsoft Xbox 360. An officially licensed BitTorrent client allows downloading to occur without the need for an additional computer.

This unit can be configured to shutdown and power up with a power timer option. I thought that would be very useful, but unfortunately, configuring this option rendered the NAS useless. Once powered off, it would not power back up, and no amount of pressing resets will fix this!
Apparently it is a known bug in the firmware and there is an update to avoid this, so check the Netgear website for info before setting this option, else you will have to return the unit for a replacement!
It's made of some sort of metal, the drive caddies are well made and fits perfectly, the fan at the back is big but very quiet and does its job.
One thing is the software setup is a bit difficult for a beginner like me. Formatting hard drives etc., is a pain, I had to read the online manual a few times.
Once setup, I was up and running and transferring pics and videos wirelessly. Comparing it with the D-Link ShareCenter, the ReadyNas is a lot quicker (about 6x at transferring files) and has better user interface.
I have tried simultaneously streaming videos to 3 computers and a netbook, with no problem.
Now trying to fiddle with additional softwares.
Disks up to 3TB are supported. You don't need to unscrew the cover to insert the disks - the grille on the front is hinged to provide access. You need to mount the disks in a sort of half-caddy, for which screws are provided, then they slide into place. When you come to format them, you have a choice of Netgear's own X-RAID2 or industry-standard RAID 0 or 1 (striped or mirrored), or you can concatenate or run the disks as separate volumes (JBOD). Having gone to the trouble of buying a 2-disk NAS, I'd assume you want to use either X-RAID2 or RAID 1, to give resilience against disk failure. I tried setting up a couple of 2TB disks using RAID 1, and they formatted and mirrored no trouble at all, in about 2.5 hours, with a usable filesystem after about 20 minutes.
There's a "RAIDar" PC app to perform initial setup, after which you switch to a web interface to manage the ReadyNAS. It's slick enough, although it takes a little getting used to (there are two manuals, for hardware and for software, both supplied as hyperlinks to PDF files; they are worth reading).
The main reason for choosing X-RAID2 over RAID 1 is that Netgear's formatting supports on-the-fly disk expansion (ie. when bigger disks are fitted, the partition grows larger without any data loss). I wanted to try this, so I removed the 2TB disks and installed two 500GB disks instead. When I restarted the ReadyNAS, I got a "Corrupt Root" error, which is because the disk had previously been used in a PC. The solution is to perform a "factory reset" boot on the ReadyNAS - this is described in the Hardware Manual PDF and involves a paperclip; you then have ten minutes to choose a new RAID configuration, or it reformats the new disks like the previous ones.
Once I had the 500GB disks configured with X-RAID2, and after they had finished resyncing (about 2.5 hours), I pulled one of the disks (cue a load of alarms and emails from the ReadyNAS), and plugged in a 1TB disk in its place (with the ReadyNAS still powered up). It automatically integrated the new disk and had a resilient 500GB partition running again in around 2.5 hours. I then replaced the other 500GB disk, and once it had finished resyncing, it emailed me to say it had detected additional disk capacity, and would automatically extend the partition at next reboot. All this time I had been playing music from files on the ReadyNAS continuously and without interruption, with all the disk swapping having no discernable impact on my use of the partition. The reboot took the partition down for around 5 minutes, then it was up and running again, letting me play music while the partition was extended in background. Once this had completed, I did the whole thing over again using 2TB disks, and it worked flawlessly. Very impressive.
It's a shame the sharing and remote access software isn't as good as it could have been. There's no iTunes server (as I believe there was on the old v1 readyNAS Duo). I have moved my iTunes library onto the ReadyNAS, but that's not quite the same. Built-in DLNA support is good, for Windows Media Player, Playstation 3, XBox 360 and the like. The PC backup software is a one-licence copy of Mimeo, available for download (don't bother). There is apparently Time Machine support, but I don't have a Mac to test this on, and you can schedule backups from the ReadyNAS, to and from different shares or to any of the three USB ports (two of which are USB3).
The shares that the ReadyNAS creates are all on the same partition, but they are useful to help you organise yourself. By default, you get a Backup and a Media share, plus you get a private share for every user you create. If you create the ReadyNAS users with the same username and password as your PC login, you don't need to supply the username and password in order to connect. The private shares appear and disappear as needed (so if Fred isn't logged in, the Fred share disappears). I've had some trouble with my own private share disappearing when I'm still logged in - I think, but I'm not totally sure that this happened when I used the ReadyNAS remote app on my Android phone. The Android app was fairly useless - I don't know if it's buggy or just lacking in features, but I could only access my private share, and it often showed no contents (despite no error). It worked somewhat better on a PC - from there I could see the backup and media shares but not my private share. I've disabled the remote app as well as the photo-sharing one. After rebooting the ReadyNAS a few times to get my personal share to reappear on my desktop PC, I had decided that the remote access add-ons were more trouble than they were worth.
For resilient network storage it's absolutely brilliant. At some point in the future I'll upgrade the disks to 2 x 3TB, and I will have no worries at all about losing data (incidentally, it is still important to back up a NAS unless you're only using it as a backup store itself, because if someone inadvertently deletes that important file, it's deleted from both disks simultaneously). I am confident that the data is secure, after having removed anonymous and "everyone" access; I am confident that if a disk fails, the ReadyNAS will tell me and will be able to reinstate resilience when I plug in a new disk. I am not going to try using the remote-access software any more: it's too buggy and/or difficult to set up for my liking.
What I am less impressed with is the firmware (version at time of writing 5.3.6). Compared to the Synology DM software it is very buggy, very slow and quite hard to understand.
Implementation of an app store is very poor. Netgear call it Genie Marketplace. (genie.netgear.com) and the device connects directly to the app store through the interface. Sounds like a good idea, but often the apps I have purchased wont install, or they wont start. Sometimes an app shows up one day, and its gone the next. Truly awful and certainly needs to be sorted out. I bought a photo app (piwigo). What I didnt realise was it seems I need the PHP app first for an extra $2.99. This isnt expained anywhere and I couldnt understand why the app wouldn't run.
The unit was hard to set up using a disk which had previously been installed in a PC.
If you are after an easy life, please don't but this item, you will be pulling your hair out. If you like a challenge, then go for it.
Oh, and the latest version of firmware the DLNA media server wont scan the files correctly. Im told this will be fixed next firmware.

Once automatic timer is set, it powers down and will not power back up.
Realy good build quality, the box is tiny but feels strong.Read more
