A RAID system 2 is a type of redundant array of independent disks (RAID) configuration that uses mirroring to provide data redundancy and fault tolerance. In a RAID 2 system, data is written to two separate disks simultaneously, ensuring that if one disk fails, the data can still be accessed from the other disk. This provides a high level of data protection and can help prevent data loss in the event of a disk failure. RAID 2 is not commonly used in modern systems, as it has been largely replaced by more efficient and flexible RAID configurations such as RAID 5 or RAID 10. **

An external hard drive RAID system is a storage solution that uses multiple hard drives to provide data redundancy and/or increased performance. RAID stands for Redundant Array of Independent Disks, and there are different RAID configurations that offer different levels of redundancy and performance. When used in an external hard drive system, RAID allows for the simultaneous use of multiple hard drives to store and protect data, making it a popular choice for businesses and individuals who need reliable and high-capacity storage solutions. **

When you play Pokémon Sword/Shield with the expansion and then switch to another system, your game progress and expansion content will not be available on the new system. The expansion content is tied to the original system where it was purchased, so you will need to transfer your game data and expansion pass to the new system in order to access it. This can be done through the Nintendo Switch's system transfer feature or by redownloading the expansion pass on the new system using the same Nintendo account. **

If you play Pokémon Sword/Shield with the expansion on one system and then switch to a different system, your game progress and expansion content will not carry over. The expansion content is tied to the specific system and game save data, so you will need to purchase the expansion again and start a new game on the new system. Your Pokémon and game progress from the original system will not transfer over to the new system. **

Yes, your explanation makes sense. While a RAID system can provide redundancy and protection against data loss in the event of a single drive failure, it does not replace the need for a backup system. A backup system is necessary to protect against other forms of data loss such as accidental deletion, corruption, or catastrophic events like fire or theft. Additionally, a backup system provides the ability to restore data to a specific point in time, which a RAID system may not be able to do effectively. Therefore, both a RAID system and a backup system are important components of a comprehensive data protection strategy. **

For a database server, a RAID 10 system is often considered the best option. RAID 10 combines the benefits of both RAID 1 (mirroring) and RAID 0 (striping), providing both data redundancy and improved performance. This is important for a database server, as it needs to be able to handle a high volume of read and write operations while also ensuring that data is protected in case of a drive failure. Additionally, RAID 10 offers better fault tolerance and faster rebuild times compared to other RAID levels, making it a strong choice for database servers. **

If you play Pokémon Sword/Shield with the expansion pass on one system and then switch to a different system, you will need to redownload the expansion pass on the new system. Your game progress and saved data should transfer over, but you may need to reauthorize the expansion pass on the new system to access the additional content. It's important to ensure that you are using the same Nintendo account on both systems to maintain access to the expansion pass content. **

Pokémon Sword and Shield are the eighth generation of Pokémon games developed by Game Freak and published by The Pokémon Company and Nintendo. They are role-playing video games set in the Galar region, inspired by the United Kingdom. Players embark on a journey to become the Pokémon Champion, capturing and training various Pokémon creatures to battle against other trainers. The games introduce new Pokémon species, gameplay mechanics, and features such as Dynamaxing and Gigantamaxing. **
