Losing your data can be devastating. Unfortunately, backing up your hard drive can be tedious and easy to forget. A simple and better solution is having your very own NAS or network-attached storage. A NAS can act as a centralized storage device for your home or office network. Your PC and other devices can use it to store important data, and if your PC fails, your data will be safe in the NAS drive.
