QNAP TS-421 NAS & QTS 4.0 OS Review
QNAP is a key player in the NAS market, and after many years of sticking to the simple but highly usable interface of the proprietary operating system for their products, they decided to upgrade to something more elegant, more appropriate to our times, with icons and lots of customization options. Their new operating system, the QTS 4.0, can easily be called a major upgrade of the older one. Offering many interesting features that will thrill most users, it makes QNAP’s products even more competitive as the QTS 4.0 is a multi-windowed, multi-tasking OS with a nice GUI resembling that of modern smartphones (IOS, Android). It is also highly customizable, allowing you to install dozens of applications to make your NAS server suit your needs. More about the QTS 4.0 can be found here. We will also take a rigorous look at it in the following review, so you had better read all or most of this review–don’t skip to the conclusion! … at techPowerUp!
