This powerful system comes without a drive, but installing your own is a piece of cake. Of all the NAS devices we tested, the Synology DS107+ promised the most extensive feature list, and the device consistently impressed us with its Swiss-Army-like capabilities on our network. The enclosure ships without a hard drive, so your first task is to install one. The instructions for doing so are simple and easy to follow, and we were plugging the device into our wireless router within minutes. (Disclosure: Synology was kind enough to install a drive in our test model, so we removed it and installed a second drive to duplicate the standard user experience.)
