World Backup Day is slowly creeping up on us. This year we will be celebrating this holiday on March 31st. The whole point of this holiday is to raise awareness of the importance of “Data” in our lives and ways we can protect it. Here at Modders-Inc, we try to review different types of storage devices which help consumers to store and backup data based on their need. One of our close sponsors recently released a multi-disk Network Attached Storage device that offers not only capacity but also able to scale and deliver content quickly and efficiently to users. DiskStation DS918+ by Synology is an ideal solution for home or small businesses to store data as a primary point and a backup. In addition to backup features, DS918+ is capable of transcoding up to two channels of H265 and H264 videos at the same time. This high-speed storage server has enough power to run a small company share with numerous features like Media Server and Surveillance Station.
