A far as the LG NAS is concerned: there are a few features it has that didn't make it into print. Those include a catalog dredger, so that duplicates of files aren't backed up (not quite data dedupe), the ability to stream virtual media discs to multiple users, and the real time backup. Remember that in a typical RAID 5 or 1 configuration, the total storage will drop somewhat. Existing backup solutions are very expensive (LTO and AIT drives are outta sight) and per GB, the storage costs are similar to BluRay. Also, most backups will be differential or incremental, and in a small work group or small/home office, I would be impressed with someone generating over 50 GB of content per day. So, yes, I do find the price quite attractive, but it is at least 6 months from announced ship date, the price is approximate, and the market will almost certainly change between now and then.
