RAID introduces algorithms to use multiple storage drives for redundancy, thereby protecting against hardware failure. Aside from the use of NAS-specific storage drives, another contributing factor is the Redundant Array of Inexpensive Disks (RAID) capability. One primary reason why we use NAS over DAS is for greater reliability. I managed to find most of the applications that came to mind easily – antivirus tool, media servers, plus file download utilities. Some are directly from Synology, but there are also many from approved third parties.

It also includes a package manager (Linux style) that allows you to choose from a list of approved applications to install. I encountered no issues setting up a custom network configuration with the Synology DS718+ I used as a sample. Not overwhelming, but streamlined while being comprehensive. For those used to Windows, you’ll be pleased to know that using DSM is very similar.ĭSM offers more user-friendly network and sharing management features than Microsoft. DSM may look very basic, but it’s very similar to a fully-fledged OS. In the case of Synology, the OS used is called DiskStation Manager (DSM), a lightweight Linux-based platform. For example, it enables the NAS to power up on its own, initializes storage devices, manages network traffic, and more. NAS units need to have their own Operating System (OS) to make everything work independently. They all have processors, memory, storage controllers, network interface, and other necessary hardware. NAS are, essentially, miniature computers. Now that the background is out of the way, let’s deal with the down and dirty.
