Why RAID redundancy is essential in NAS storage systems

Data redundancy is an essential conversation when discussing data storage systems. When data is lost on an enterprise NAS device. It can have a significant impact on the organization. RAID storage systems help to keep data available. By redundantly storing information on multiple disks. This way, if one disk fails. The data can still be accessed from the other disks in the array. Small businesses often use RAID storage systems. To share data between multiple users or computers on the network. This way, if one computer fails, the data can still be accessed from the other computers on the network. Data redundancy is an essential conversation when discussing any type of data storage system.

RAID redundancy is essential in NAS storage systems. Allowing data to be protected if one drive fails. But this isn’t the only reason. Here we will see all the good reasons you should connect your NAS storage drives in RAID.

What is RAID redundancy?

RAID is a storage technology that combines multiple disk drives into one logical unit. This allows the disks to work together for greater availability, reliability, and performance. RAID is commonly used in servers and storage systems. It can provide a significant increase in performance compared to a single disk. Furthermore, RAID can also provide redundancy. Meaning that if one disk fails, the data can still be accessed from the other disks in the array. There are many different types of RAID. Each with its own benefits and drawbacks. However, all types of RAID share one common goal: to improve storage performance and reliability.

Even though NAS storage is superior to traditional storage. They’re not without fault; even the best NAS systems can still break. And when one fails, it brings down the entire infrastructure. To prevent this, you can implement RAID redundancy. On your hard drives to protect against failure and increase the performance of your system.

Here is why RAID setup is essential in every Network Attached Storage setup.

Aligning your valuable data across multiple drives makes it fault-tolerant.

RAID allows you to create fault-tolerant arrays with your drives. So that if one of the drives fails, you can rely on the others to have your data intact still. This is especially useful for enterprises. Running huge applications or providing SAS services. If you are looking for highly fault-tolerant NAS appliances. With additional security features like Immutable delta-based snapshots. Write-Once Read-Many (WORM) volumes, and Sync/async multi-appliance/multi-site replication. We suggest you check out StoneFly.

Increased throughput

When it comes to data storage, RAID provides a number of advantages over traditional disk drives. The main benefits is increased output. By combining multiple hard drives into a single array, RAID can greatly increase the speed or processing power of a workstation. In addition, the use of larger capacity hard drives can help to improve performance even further. Furthermore, RAID offers improved data protection by redundancy. If one of the drives in an array fails. The data can be restore from the remaining drives. As a result, RAID provides both enhanced performance and improved data security, making it an ideal solution for many businesses.

Reduce the cost of ownership

Reducing the cost of ownership. It is another widely recognized benefit of RAID. Particularly of RAID 5 implementations. Due to their lower need for maintenance. Hard drives do not fail together too often. Still, if more than one drives fail. Higher levels of RAID can take care of it. In a study done by Carnegie Mellon University. It was found that using RAID. Can increase the Mean Time Between Failures (MTBF) by up to three orders of magnitude. In other words, with RAID you are far less likely to have a drive failure in the first place. Even if you do have a drive failure, the increased reliability of RAID means that it will take far longer for another drive to fail. This reduces the cost of ownership by lowering the probability of data loss and reducing the frequency of drive replacements.

Bottom Line

The value of the RAID is exemplary. RAID can improve availability and reliability. It supports systems with mission-critical applications, with 24/7/365 clusters, petabytes of storage, and massive IOPs loads. Even though not all applications are suitable for RAID infrastructure, admins continue to use it because it’s the only way to ensure having a reliable system. That’s why almost 90% of enterprise deployments are using RAID storage.
