In fact, the Synology devices run their own incredible operating system, called DiskStation Manager. They're more like ultra power-efficient mini computers. This makes a NAS a great central backup point and secure file store, such as family photos.Īnother reason to use a NAS is that they're not just a case for some drives to sit in. The NAS does it all for you, and will audibly alert you if one of the drives needs replacing, without any data loss being suffered. Using a NAS makes securing your data like this an invisible process. Hard drives can fail at any point, and if you don't have multiple backups, you lose everything. This means one drive acts as a duplicate of the other, such that if one failed, you wouldn't lose any data. If you have more than one hard drive bay in your NAS (the Synology DS220j has two), you would typically configure one hard disk for data redundancy. Not just computers, but tablets, smartphones, games consoles, and smart TVs too.Īnother benefit is data security. The immediate benefit of doing this is that every device on your network will be able to access the files stored within. The "network-attached" part means that rather than plugging a hard disk into your computer through USB (sometimes called Direct Attached Storage), you plug it into the network instead. Since this is an entry-level NAS device, let's take a moment to explain what Network Attached Storage is, and what you might want one. What is a NAS, and Why Would You Need One?
