The ease of use, ability to control everything remotely from anywhere in world via web browser or mobile app is great for our small business which operates out off site! Nothing really that I dislike about this NAS system other than it being pricey but if you can afford then go ahead & get one because its worth every penny!! We have been able store all types files such as images/videos etc with no problems at all so far we are very happy customers who would recommend anyone else using qnap products due them working perfectly well since day 1 they were purchased over 3 years ago now!
