FAQ

An HDD RAID (Redundant Array of Independent Disks) is a storage solution that combines multiple hard disk drives into a single logical unit for improved performance, data redundancy, or both. By distributing data across several disks, RAID can increase speed, provide data backup, or balance both depending on the RAID level used.

Common RAID levels for HDDs include RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 5 (striped with parity for a balance of speed and fault tolerance), and RAID 10 (a combination of mirroring and striping for both performance and redundancy).

Yes, you can use different brands of hard drives in a RAID setup, but it's recommended to use drives of the same capacity and speed for optimal performance and reliability.

While some motherboards support basic RAID configurations, for advanced RAID levels or enterprise use, a dedicated RAID controller card is recommended for better performance and management features.

Some RAID controllers and software solutions support expanding an existing RAID array by adding more drives, but the process and compatibility depend on the RAID level and the controller used. Always back up your data before attempting any expansion.
