RAID level comparison

RAID level: the most important RAID concepts compared

When combining hard disks in a RAID, you can choose between different standard setups called RAID levels. The predefined combinations determine the arrangement of individual hard disks and methods to store data in a RAID network. But what are the approaches of the most important RAID levels? And which one should you use?

DRaaS

Disaster Recovery as a Service (DRaaS): the more advanced backup

Throughout the course of digitisation, employees and employers became aware of the importance of backups. The 3-2-1 rule was considered the golden rule - where two redundant copies of each file are kept. As technology continues to evolve, cloud-based solutions are becoming more popular. Thus, Disaster Recovery as a Service has established itself as an important cloud service.

Cloud disaster recovery

Cloud Disaster Recovery: well-prepared for worst case scenario

One of the biggest tasks for IT managers is to ensure the long-term security of data, software, and hardware. Where issues arise, a rapid recovery is essential. Cloud Disaster Recovery (Cloud DR) is a concept that is ideally suited for these purposes. But what exactly distinguishes cloud protection and how does it differ from conventional backup solutions?

Data sovereignty

Data sovereignty: an explanation

What happens to digital data after a company stores contacts, emails, and files in the cloud? Businesses that work with third-party providers need to know who retains data sovereignty over business and customer data when it is stored on external servers. Read on to find out how data sovereignty is legally regulated.

RAID 10

RAID 10: Mirroring and striping combined

RAIDs are a good solution for improving the performance of hard drives. The individual standardised levels provide different approaches to boost reliability or the throughput rate of system networks. RAID 10 relies on complete data redundancy. Data is stored in a distributed manner and can be read quickly. Find out what’s behind the RAID level!

RAID 6

RAID 6: Storage technology to minimise data loss

Combining hard drives to form a RAID is an attractive solution to optimise the performance and security of individual drives. One such approach that’s been hailed for its high safety factor is the RAID 6 technology. As an extension to the popular RAID 5 level, this network protects from data loss when two hard drives fail – all without having to duplicate your data manually.

RAID 5

RAID 5: What you need to know about the RAID level

A Redundant Array of Independent Disks (RAID) can be used to improve data security or the performance of storage solutions. The specific advantages of a network depend on the selected RAID level. Find out how RAID 5 – a system of three or more hard drives – can improve security and throughput rate.

RAID 1

RAID 1: understanding the hard disk compound

Hardly a storage concept embodies the RAID principle (Redundant Arrays of Independent Disks) as well as RAID 1 in which two or more hard disks are linked to save copies of data for access in case of system failure. Find out more about RAID 1 and why mirroring makes this network so special.

RAID 0

RAID 0: what’s behind the RAID level?

A Redundant Array of Independent Disks, or RAID for short, is a combination of several hard disks to form a single logical drive. Systems like these typically follows a redundant storage concept for higher security. The standard RAID 0 is an exception because it only seeks to optimise the data throughput by coupling several hard drives.

RAID

What is RAID (Redundant Array of Independent Disks)?

When the RAID concept was first introduced in the late 1980s, it was primarily intended as an alternative to high cost hard drives on mainframes. While the issue of cost has shifted somewhat into the background, RAID storage systems are still in demand because of their high reliability in a server environment. What’s behind the technology and what are the various RAID levels?
