NAS is virtually a network-attached hard drive. Instead of plugging it into your computer, it is accessible over the network or even internet just like Dropbox. It is usually having two or more drives inside the case and it protects your data even if one or more drives get broken. Kind of magic, but it is called RAID protection.Sound encrypted, I know. But in human language it means:RAID1 - two disks mirroring each other, if one gets damaged other still has a copy of your dataRAID5 - also a single disk failure protection. For 3 or more disks.RAID6 - two disk failure protection. For 4 or more disks.
