There are a few things to consider when setting up and operating a RAID system. Firstly, you need to decide what type of network you want to set up. For example, if you’re only looking to increase data throughput, you could use a level 0 system or alternatively opt for an SSD. If you want to boost data security, you could choose between mirroring (e.g., level 1) or storage with parity information (e.g., level 5).
When selecting hard drives, choosing identical models is preferable. In many RAID setups, the maximum storage volume depends on the smallest disk, which is why storage potential may be lost when mixing hard drives of different sizes. More importantly, rely on hardware such as NAS that are designed for endurance and a longer life. The size of the data carrier also plays an important role when defective hardware is replaced later or when the RAID is enlarged: new or added components must be at least the size of the smallest existing or defective data carrier.
Here’s an important reminder when using RAID systems: while the interaction of hard drives improves the security of the stored data through redundancy, it cannot replace a good backupsolution.
