Home NAS continues to become larger and larger, at least in terms of space if not popularity. While most commonly seen in small offices or people with decked out media centers, the advantages of having very large amounts of storage centrally accessible is something that many can appreciate. Hammer is introducing their “MyShare” series of NAS devices, which offer capacities from 320GB to a massive 2TB, all of which is supported by multiple modes of RAID (depending on how you configure it) an the ability to attach USB devices to it, such as additional storage.
A NAS is always going to be more pricey per gigabyte than a standalone drive, and these aren't any exception. A 1TB edition will run you up to $500, though I've seen it as low as $430. All the units will be available by this August.
