QUESTIONS & ANSWERS
The most frequently asked questions about RAID
What is RAID and what RAID levels are there?

RAID (Redundant Array of Independent Disks) is a technology for combining several physical hard disks into one logical drive. There are different RAID levels, such as RAID 0 (striping), RAID 1 (mirroring), RAID 5 (striping with parity), RAID 6 (additional parity) and RAID 10 (combination of RAID 1 and 0). Each level offers different advantages in terms of speed, data security and reliability.
What is the difference between RAID 0 and RAID 1?

RAID 0 offers better performance because data is distributed (striped) across multiple hard disks, but it does not offer data security - a failure of one hard disk leads to data loss. RAID 1, on the other hand, mirrors the data on two hard disks, so that in the event of a hard disk failure the data is still available on the other one, but there is no performance gain.
Which RAID level is best for my needs?

The choice of the best RAID level depends on the requirements. RAID 0 is ideal for performance, RAID 1 for simple data protection, RAID 5 and 6 offer a balance between performance and security, while RAID 10 offers high performance and redundancy. The right choice depends on whether the priority is speed, data security or a combination of both.
