Hexus posted a review on the Qnap TBS-453A NASbook
A quote from the article:
A four-bay portable NAS with M.2 storage and a built-in network switch. Network-attached storage has evolved to such an extant that today's servers can be thought of as the swiss army knife of computing devices. Be it centralised storage, media transcoding, company-wide backups or IP-cam surveillance, most modern NAS solutions are versatile enough to tick all these boxes and more. They are, in short, a useful addition to any home or office.Qnap TBS-453A NASbook Review @ Hexus
Yet the NAS marketplace is mighty competitive, with numerous high-profile players all vying for customers with a similar feature set. And given that there tends to be little romance surrounding these units - they're typically small black boxes that mainstream users could easily overlook - there's real benefit in being able to stand out from the crowd.
