I would wait for the first couple of hands-on reviews...
Like the title says, before buying make sure you properly research this product. Don't go for glorified press release reviews, make sure the reviewer actually touched, installed and worked with the product for a while. To write the words 'no crash protection' and 'home network storage' in the same sentence does not bode well for the product :-)
Bought a Seagate BlackArmor 420 a while ago, it works, barely. Am only using the Network Storage part of the NAS, the other stuff takes too much time to configure and troubleshoot, etc.
Looking at the product forums at Seagate, tech support seems to be seriously lacking, firmware updates are far and few in between, and what's promised in press releases and printed on the box is not always what's delivered in reality.
Stuff no longer working after firmware updates (for instance, temperature indication always stuck at 105 or 109 degrees fahrenheit) does not give high hopes for future products.
Proceed with caution.
