If you are looking for a network storage solution that you can access remotely, the MyDitto could be one of the simplest and surprisingly cost effective solutions out there.
I say "could" because it's impossible to pass judgment on the MyDitto without knowing the details on the software, but the device does handle RAID 0 or 1, it has USB ports for added storage and users can access their information from anywhere by simply plugging in a MyDitto USB key. Since no software is stored on the computer itself, it can be used on any computer without running a security risk. It's also compatible with Windows, Mac and Linux as well as WinMo 6.1 and iPhone smartphone platforms.
At $US249 for a 1TB model it's fairly affordable when compared to many Windows Home Server solutions, and there are no subscription fees. However, if you have a little more experience with home networking you might be interested in the Iomega IX2-200. It has loads of features for the price and it does its job well.
