How to replace a failed or faulty HARD DISK on your QNAP NAS

It's not something we hope for, but unfortunately from time-to-time hard drives fail. In this video, we show you how to replace a failed hard disk in your QNAP NAS. We recommend that as well as backing up your data on a regular basis, make sure you always configure your drives with some level of RAID (Redundant Array of Inexpensive Disks). What Are the Types of RAID? RAID 0 (Striping) (Not recommended) RAID 0 is taking any number of disks and merging them into one large volume. This will greatly increase speeds, as you're reading and writing from multiple disks at a time. An individual file can then use the speed and capacity of all the drives of the array. The downside to RAID 0 though is that it is NOT redundant. The loss of any individual disk will cause complete data loss. This RAID type is very much less reliable than having a single disk. RAID 1 (Mirroring) While RAID 1 is capable of a much more complicated configuration, almost every use case of RAID 1 is where you have a pair of identical disks identically mirror/copy the data equally across the drives in the array. The point of RAID 1 is primarily for redundancy. If you completely lose a drive, you can still stay up and running off the additional drive. In the event that either drive fails, you can then replace the broken drive with little to no downtime. RAID 1 also gives you the additional benefit of increased read performance, as data can be read off any of the drives in the array. The downsides are that...
