get what you pay for
Want better security? buy something with real support, nobody in their right mind should buy a NAS from a company like Seagate and expect anything great out of it.
Want better protection buy an enterprise product, they are not perfect of course but at least organizationally they are much better geared to deal with this kind of thing, I have no expectation that Seagate (or any of the 10s to maybe 100 small NAS vendors out there) to have that level of structure. I say that as someone who has worked closely with software development teams for the past 15 years now(not related to storage, more related to SaaS/online transaction type systems)
