May 19, 2021 | CM

May 19th, 2021 Shenzhen, China - TerraMaster, a professional brand that specializes in providing innovative storage products for home, businesses and enterprises, discusses the difference between software RAID and hardware RAID to help professionals in choosing the right RAID storage. The TerraMaster Thunderbolt 3 Series features professional-grade RAID for all types of users.

Today, RAID storage is used in homes, small and mediumenterprises, and large corporations. RAID stands for “Redundant Array of Independent Disks”, a data storage virtualization that allows you to combine multiple storage drives to create one or more logical units for different purposes such as larger storage space, improved read/write performance, or a balance of both.

What are Options in RAID Storage?

There are two main RAID options today for professionals – software RAID and hardware RAID.Software RAID can be easily incorporated in an existing computer or server without the need of additional hardware. On the other hand, hardware RAID uses dedicated hardware to create RAID function in a computer or server.

If you are new to RAID storage systems, learn about the differences between the two options, its advantages and disadvantages in our simple comparison below.

Comparing Software RAID and Hardware RAID

SoftwareRAIDuses the computing power of the computer or server’s CPU which is shared with the operating system and other applications running in the background. This shared workload reduces the CPU’s computing performance for other tasks. Many operating systems support RAID configurations. However, partitions cannot be shared with other operating systems.

On the other hand, hardware RAID makes use of a RAID controller which has its dedicated processor.A RAID controller can be added to the motherboard or on a different server. Furthermore, dedicated RAID storage devices are also available which runs independently. Hardware RAID options have very little utilization on the computer or server’s CPU, offering better overall performance compared to software RAID options.

Here’s a simple comparison between software RAID and hardware RAID below.


Software RAID

Hardware RAID




Very low. Can be configured with existing computer/server



Dependent on RAID controller hardware for computer/server





Limited to CPU


Dependent on RAID controller


Security and Backup



Limited to software features


Available in software and hardware options

Multiple OS compatibility


RAID Storage for Professional Content Creators

Most professionals like video editors, photographers, and other content creatorsopt for hardware RAID options for many reasons. It offers better performance having a dedicated RAID controller or dedicated RAID storage. It is highly scalable, easily allowing users to add more storage space by simply adding another RAID storage in the network. Dedicated RAID storage devices also have more robust security and backup features which come in both software and hardware aspects. Furthermore, RAID storage devices can be shared across different operating systems making collaborations easy.
