Using the data virtualization technique, several physical disk drives - either SSDs or HDDs are combined into one logical unit that is capable and improved upon performance, data redundancy, or both at the same time. Normally the RAID is employed in network-attached storage (NAS) environments, well known for a massive storage, backup, and media streaming solution. These configurations offer fault tolerance, strong performance, and increased storage capacity, using the redundancy in a well-balanced manner to increase the performance of the system many folds. for a video editing workflow, you’ll need high read-write speeds or for a business archive you’ll need redundancy, all these and other requirements can be fulfilled using the RAID system. RAID offers several configuration options to suit the specific needs and demands of an environment i.e. The RAID can be deployed in two types – a hardware RAID (RAID controller or RAID-on-chip) or a software RAID (software-only or hybrid). Requiring minimum input from the storage administrators in monitoring, maintenance and reducing the cost of adding more and more drives for up-gradation as compared to in another environment such as JBOD (just a bunch of disks). RAID is designed keeping in mind to improve upon performance and redundancy in storage systems. Working with multiple large size media and information files you will conceivably need more storage space and redundancy than a single drive would be able to offer.
RAID – redundant array of independent disks, are disk arrays fused and operating as one super hard drive. Redundant Array of Independent Disks (RAID)
So, which one of these data storage technologies is better? Or can they be used interfused? Let us examine both technologies and how they build upon each other. RAID and NAS are the two most used of these and overlap in many instances, though they are fundamentally different in some ways. In today’s modern time the storage technologies are rapidly evolving to the needs and wants of users.
