Storage is no longer a matter of throwing another disk drive into the computer and calling it a day. There are many more issues to take into account besides a few more gigabytes of room. Today it's a matter of not only what you store, but how that data is going to be accessed and used. At work, data is king and the lifeblood of the enterprise. At home, our lives are becoming media-centric with a growing need for not only storage space, but ways to serve and share the media as well.Network attached storage (NAS) servers are not just for businesses any more. The same benefits they offer in the work place, namely secure, sharable storage, can be used in the home/small office environment as well. Today's crop of NAS devices offer more than just storage though, as they can also be used as media servers to share photos and videos across the network and make files available via the Internet as well. Many units offer iTunes support and can even function as a web server, and any multi-bay unit will offer some form of redundancy through the use of RAID volumes.Today we'll be looking at the Thecus N4100PRO, a 4-bay NAS server designed for the small business or enterprise work group. The N4100PRO is the big brother to the Thecus N3200PRO we reviewed previously here at OCC. Thecus offers a full line of storage products ranging from 8-bay enterprise class NAS servers to single- and dual-bay units for home use. The N4100PRO has been part of the lineup since Thecus introduced it over 15 months ago, however the version we'll be examining is based on the just-released AJAX-based user interface that offers a cleaner look and more features including iSCSI support.
