The SheevaPlug prototype uses an 8GB thumbdrive as its NAS storage. However, it can work with any USB external hard drive. In CNET Labs' test, the drive had an excellent read speed of about 30MBps (about the same as most external hard drives) while its write speed was less than average, only 6.5MBps.
Once you plug the computer into power and to the network, you can manage and access it in two ways. Via the Internet at www.myhipserv.com and via the local network by typing its IP address into a browser's address bar. Now you can sign in its Web-interface.
