Article – From the horse’s mouth
The Sony WG-C10N is like most other mobile network-attached storage devices in that it requires the mobile device to be effectively attached to its own wireless segment. Of course it can work as a bridge between an existing Internet-connected network and your device like most mobile NAS devices. As well, it requires the use of a mobile platform app or the use of a Web front for users to benefit from the data stored on the NAS using the Wi-Fi network.
This means that it can’t work with existing wireless home networks, nor can it support SMB/CIFS network file transfer that is common on regular computers nor can it serve audio-video content to DLNA-capable media devices.
But unlike the other mobile NAS devices that are on the market, this device works simply as a file server for attached SD cards or USB flash drives rather than using an integrated storage medium. This is more so for those of us who want to use higher-capacity memory cards or USB thumbdrives or have a collection of different SD cards / USB thumbdrives for different applications.
It also works as an SD card reader for those of you who don’t have an SD card slot in your computer or similar device (think of the Dell XPS 13 Ultrabook that I previously reviewed) to view or download your digital camera’s “film roll”. As well, it is one of the first “mobile NAS” devices that can serve as an external battery pack for your power-thirsty smartphone or tablet.
