The Good The Buffalo CloudStor Pro NAS server is fast and adds a large amount of storage to the free and user-friendly Pogoplug cloud service. It offers Active Copy for Windows and supports Time Machine for Mac as backup solutions.

The Bad The Buffalo CloudStor Pro NAS server depends on the Internet and software for most of its functions to work and offers limited features for local network. It doesn't support backing up to an external hard drive, takes a long time to build RAID 1, and is rather buggy.

The Bottom Line Based entirely on the Pogoplug service, the Buffalo CloudStor Pro NAS server makes a great investment for Pogoplug fans. Its lack of support for general local network features will make others think twice about getting it.

Remote access over the Internet is generally a desirable feature in a network-attached storage (NAS) server, but the Buffalo CloudStor Pro goes a little too far in that direction. The device is all about the Internet. It's basically the first complete dual-bay server we've seen that's based entirely on the Pogoplug service. That said, the server requires a live Internet connection for the setup process and most of its functions to work, while neglecting features for the local network it's plugged into.

With the street price of just around $240 with one 2TB hard drive included, and offering fast throughput performance, the CloudStor Pro will definitely make any die-hard Pogoplug fans happy. Those who don't want to compromise the local network services, however, will find it painfully lacking. For a balance of the cloud and local network storage, you should also check out the Iomega Home Media Network Hard Drive Cloud Edition.

Design and ease of use
Measuring 8.1 inches by 5.1 inches by 3.4 inches, the Buffalo CloudStor Pro is just slightly larger than two 3.5-inch hard drives put together, which is as compact as a dual-bay server can be. The hard-drive bays are front-accessible, and users can add/remove the hard drive without any tools. On the back the server has one Gigabit Ethernet port and one USB 2.0 port that can be used to host an external hard drive.

With one hard drive included, the CloudStor Pro is super easy to setup, as long as you have a live Internet connection. The server doesn't come with instructions or software, just a small piece of paper that points you to the setup Web site. Here, after a few clicks, the server is set up and you can go there again each time you want to access its Web interface via a browser. You can also download Pogoplug Drive software (available for Windows, Macs, and Linux) if you want to be able to copy files back and forth to the server via drag and drop. Note that without a live Internet connection, it's basically impossible to get the server up and running. This in itself means the server is not meant to work as network-attached server but more of an Internet-attached server.

The server doesn't offer the ability to back up its internal data onto an external hard drive connected to its USB port. This means that for data integrity, you'll have to immediately think about getting a second hard drive and setting it up as the mirror of the first one, in a RAID 1 configuration. This is also the only RAID setup the server supports. For those who want a large amount of storage and don't care about the safety of their data, there's no RAID 0 option. You can set up the second hard drive as a separate volume, however.

Setting up the second hard drive into RAID proved a little tricky in our trials. First off, the server wouldn't recognize a new hard drive until we restarted it. This means the server doesn't support hot-swapping, one major feature of RAID 1. Secondly, the process of creating the RAID was rather buggy. While this process seemed easy enough and can be done via the Web interface, we had to try three times. The first two times, the server would just stop the RAID-building process after about 10 minutes and exited out of it without showing any error messages and without completing the RAID. The third time, we were able to get through the whole process, which took about 16 hours to finish adding another hard drive of 2TB.

(Note that while the RAID setup can be managed via the Web interface, this must be done from a computer that's connected to the same local network as the server. This feature can't be managed remotely via the Internet.)

It's generally normal that RAID building takes a long time, but in the case of the CloudStor Pro, we couldn't access the server during this time. With other servers, the RAID-building process doesn't stop the servers from serving data; it just slows them down. So, make sure you get the RAID setup done during a time you don't need to access your data.

The Buffalo CloudStor Pro doesn't come with instructions in case you want to replace its included hard drive, which contains its operating system, with another. This means that it would be tricky if this hard drive dies (and you don't have a RAID 1 setup), forcing you to install the server from scratch with a brand-new hard drive.

Features
The Buffalo CloudStor Pro works exactly like any Pogoplug device, such as the Pogoplug 2 . You can easily share data stored on the server with anybody just by clicking on the Share button (within the Web interface) at the bottom of each folder that you want to share and send e-mail to that person; you can take away the share capabilities by removing the person's e-mail. You can also publish supported content directly onto social Web sites such as Facebook and Flickr.
