The Cloud Engines Pogoplug also makes it easy to share files with others. You can set the whole drive or specific folders for sharing via an RSS feed or an e-mailed link. You can also open drives or folders for public viewing for anyone via a specially generated URL (similar to how Google Docs works). And a recent update allows for files to be shared by links via social media sites (such as Twitter, Facebook, MySpace). While this works well, we found a potential bug: the notifications (via e-mail and social networking) seemed to only work the first time but not every time a shared folder was updated with new content, even when we made sure this option was enabled.
As a bonus, there's an iPhone app that works very well in several respects. Files can be accessed remotely and even downloaded to the app itself for offline viewing. Music streaming over 3G sounded excellent and worked smoothly, but the app only plays individual tracks--you can't access playlists, nor can you play all songs in a folder. Video playback was slow and problematic, even over Wi-Fi, but we could view Office docs in full formatting.
Security is always a concern for "cloud-based" applications, but Pogoplug's developers claim that the company doesn't keep any data on its servers. Likewise, the company has a "doomsday plan" in place, should it ever go out of business, that would open the source code to a possible successor to restart the service.
The Pogoplug is covered by a one-year warranty for defects, as well as a 30-day return policy. The Pogoplug Web site offers plenty of useful tutorials and FAQs, and the support staff is reachable by e-mail from 9 a.m. to 6 p.m. PST. Also, Pogoplug has licensed its technology to Seagate for inclusion in that company's DockStar base station. However, Seagate is going to charge $30 per year for the capability to access the DockStar drives from outside your home network--which makes the no-fee Pogoplug a better deal, since it also works with Seagate drives.
Our biggest and only beef with the Pogoplug was its inability to share files with anything besides a PC or iPhone--it doesn't offer DLNA (Digital Living Network Alliance), UPnP, or SMB file-sharing support. That means you can't access Pogoplug-based files on non-PC media devices such as the PS3, Xbox 360, and network music players such as Sonos and Squeezebox. This is not a deal-breaker considering the device's niche, but still we hope that this will be added via new firmware sometime in the future.
If you don't need that sort of support, though, the Pogoplug is definitely a "greener" alternative for anyone who would normally use a PC as a file server. The Pogoplug draws between 6 and 8 watts of power while operating (with a Western Digital Passport drive plugged in), which means it'll cost less than $2 per year to operate. That's compared to a desktop PC, which would cost $20 to $60. That means, over the course of two years, the Pogoplug's energy savings could literally pay for itself, if you replace your PC-based file server with it
All in all, the Pogoplug make an excellent network device for anyone who wants a simple and quick solution for sharing files on a network or over the Internet. For $99, it's a fun way to build yourself a cheap online storage drive.
Editors' note: We consider the Cloud Engines Pogoplug an accessory and therefore didn't put it through the same testing process as standard NAS servers.
