As the popularity of NAS devices (or NAS servers as we like to call them) keeps increasing every day naturally many of you expect from us to focus in getting some of the latest models to hit the market from all the major players for testing purposes. Well lately we've seen the introduction of not only expensive models designed and manufactured by both old and new companies with business customers as their main target audience but also low and mid-end ones developed mostly for house and office use. That being said with the current state of HDD prices it really doesn't come as a surprise to see that consumers are not as interested in single bay models as they are in dual and quad ones and who can blame them since having at least one more available bay for future expansion is the obvious choice. So for the past two weeks we've been putting the latest quad bay NAS servers to hit the market by QNAP the TurboNAS TS-420 through rigorous testing to see if it has what it takes to win the hearts of home and office users.
