Your Own Entertainment Center

Download Station functions as a 24x7 BitTorrent, FTP, HTTP, eMule, and NZB download center without a PC. The eMule download engine allows search-n-download capability with a web-browser without installing additional desktop applications.

DLNA/UPnP Compliant Media Sever allows you to stream multimedia files with an UPnP Digital Media Adapter (DMA) to a stereo system or a TV-set. Sony PS3 and Microsoft Xbox360 are also supported.

iTunes® Server is an easy way to share music with other iTunes clients over the network. Password protection prevents unauthorized sharing.

Back Up Your Precious Data

DiskStation Manager offers comprehensive solutions for you to back up data stored on DiskStation or your desktop computer to the DiskStation.

Server backup includes two alternatives: Network Backup and Local Backup. Both allow you to back up data in the shared folders and databases. Incremental backup option and flexible schedules are available. All can be easily configured with a step-by-step wizard.

Desktop backup provides your Windows PC with Synology Data Replicator for backing up desktop data, Outlook, and Outlook Express emails to your DiskStation by choosing one of the three backup modes: Immediate, Sync, and Scheduled backup, while Mac OS X users can use Apple Time Machine backup application to back up their critical data to DiskStation.

USBCopy allows you to quickly back up your data from an USB storage device such as an USB flash or USB card reader to your DiskStation with just one single touch on the front-panel copy button.

Enrich Your Web Presence

Photo Station simplifies photo, video, and blog sharing over the Internet. The flexibility of photo theme customization, blog layout arrangement, visitor's privilege setting, RSS feed, and the dazzling 3-dimentional photo browsing with Cooliris make Photo Station your state-of-the-art lifestyle sharing center on the Internet.

Web Station with built-in PHP+MySQL allows you to publish your own websites or install numerous popular open source programs.

Access With Your Mobile Device

The iPhone and Android App, DS audio, allows you to stream music stored on your DiskStation with your mobile devices where Internet access is available, while DS photo+ allows browsing and uploading photos and videos stored on DiskStation from your mobile devices.

If you own a mobile device running on Windows Mobile® 6.0, iPhone OS 2.2.1 onward, or Symbian OS 9.1, you can log on your DiskStation to view photos with Mobile Photo Station and read supported file formats with Mobile File Station wherever Internet access is available.

5* Excellent small NAS unit
Reviewed by ScottK on 10/01/2011
Very simple to use and set up, and the documentations in't too bad at all. Takes a while to get it ready to use, I've got mine as a RAID0 with 2x2Tb drives and the format took several hours. But once online it's a breeze to use, plus the Squeezebox server add-on is fantastic as is the UPmP service. I've now got my data all backed up and my music and videos streaming nicely in my living room. Only slight negative is that it was a bit pricey, but overall I'm very happy with the device.
5* Ideal NAS Drive
Reviewed by Anonymous on 20/01/2011
I've got mine as a RAID1 with 2x2Tb drives and the format took several hours. Streams videos, music and photos to my Xbox360 and Sony BluRay player and does my 2 pc backups and it gives you loads of Internet stations on DLNA devices. Only problem is Xbox plays MP4 videos and Sony BluRay plays MPG videos (not synology's fault except it doesn;t transcode of course).P.S. used 2 x Seagate Barracuda disks - ST32000542AS. Very quiet and cool.
5* Good value NAS box
Reviewed by John on 22/01/2011
An excellent little NAS box. I thought it was a little expensive but for what I was looking for - network storage is is ideal. Still reading the manual to see what some of the other features can do for me but I suspect I will never use the downloading facilities etc.

The backup software was reasonably intuitive to use but gave some headaches the slower laptop and some unreasonably long filenames being rejected by the software.
5* A++
Reviewed by Ben on 21/12/2011
Like some of the other reviews on here, i spent many hours on the web reviewing different NAS devices. I came to the conclusion that you get what you pay for. It would seem based on features vs performance vs price this box came up top, and i haven't been disappointed! Not only have i backed up all the devices on the network, i have got my own website hosted on here, as well as all my music and films which i can stream to my iPhone or DLNA enabled TV. If you are really stuck deciding which one to pick, i can honestly say go for this one! You won't be disappointed :] A++
5* Excellent
Reviewed by Rob A on 31/10/2011
I would be lost without this device now. It is basically a simple linux pc but what makes it work so well is the DSM operating system. To use as a simple file server/backup device is very simple. For mac users it is also time machine compatible so makes a much cheaper and more versatile version of the time capsule.

This device allows me to run my own 'cloud' storage, serving up all my files to me across my home network and even across the internet when necessary. It is iTunes home sharing compatible and DNLA compatible so I now have all my music and films stored and backed up in one place. It streams to my iPhone and PS3 which is excellent.

It runs my bit torrent downloads in the background and often overnight but uses much less power than a conventional PC. It has been running now for over a year, powering up in the morning and then shutting down at night whilst during the day streaming to multiple devices and downloading bit torrent!

Highly recommended
