RAID stands for Redundant Array of Independent Disks. It is an improved system where different drivers are stacked together. It serves as the finest way to secure your information against hardware failure. The RAID controller is a card or chip equipped with storage drives (usually HDD drives) and OS. RAID provides data redundancy and improves the performance of hard disk drives. 

They are booster cards which are a few of the greatest sought-after hardware accessories according to tech nerds and PC enthusiasts. Moreover, RAID controllers boost your PC rate. They are categorized depending on various characteristics like type of drive i.e. SAS or SATA, the number of ports supported, the particular RAID levels, and the number of industries they could help. If you go through the present article, you can pick up the best RAID controller by going through the following selection.

How To Pick The Best RAID Controller?

You must know the important parameters to consider before buying a RAID controller. After assessing your needs and budget, you can determine the best RAID controller that suits your needs.

1. RAID Levels

RAID 0

It is excellent for enhancing the speed and reducing redundancy. With the inclusion of disk striping, it categorizes data between multiple drives. So, it improves performance.

RAID 1

The RAID 1 controller secures data with the enhanced speed because the information is mirrored twice. Minimum of two drives are required to work. RAID 1 is a cost-effective alternative if you want to boost speeds with data redundancy. Furthermore, it is a suitable amount of protection and offers improved uptime. Note that RAID 5 and 6 might not be perfect for writing functions. Hence, if you want to write more, you must choose RAID 1.

RAID 10, also known as RAID 1+0

This type of RAID controller requires a minimum of 4 drives that split data among themselves to boost speed and redundancy. To boost overall performance, RAID 10 or 1+0 controller is an ideal choice. However, it is the most expensive one. The price is worthwhile considering the decent redundancy and excellent reading and writing speeds.

RAID 3

Raid 3 uses separate disks to retain the parity information.

RAID 4

It is suitable for only sequential access to data.

RAID 5

It maintains an excellent balance between speed and redundancy. It requires at least 3 drives. Moreover, it strips data across multiple drives to restore data when a failure takes place.

RAID 6

RAID 6 is known to be the reliable one of all modes. It can save two disks from failing because it contains two parity-driven strips. For this RAID type, SATA drives works best. If you demand high reading operations then RAID 5 or 6 are more convenient options. 

2. Number of RAID controllers required

The number of RAID controllers you require differs based on applications. If you choose RAID 5, at least 3 drivers are needed. RAID 10 and RAID 6 need at least four drives. These many drives are the required numbers required for such controller cards to offer appropriate redundancy, disk space, and enhanced performance.

If you want to expand your storage, performance, or redundancy, you could add more array disks to the operating system. Note that adding extra RAID controllers also increases the costs.

3. The number of disks in a RAID array

You need to determine the number of disks present in your RAID array and whether you want to add more later or not. You must calculate whether you would require more storage devices in the future and the number of disks you will need. Each RAID controller comes with the upper limit of storage devices you can connect to it. Hence, you should know the amount of storage required.

4. Hardware RAID Or Software RAID

Software RAID removes the need for adding a physical card to the CPU. Compared to hardware RAID, they are cheaper. Conversely, hardware RAID provides extra advantages like outstanding processing power, improved cache, improved redundancy, support for power failure, enhanced storage, and more. These benefits come at a cost and so hardware RAID is expensive.

For Windows based systems, a hardware RAID is recommended. This is because they can boost your overall performance. With a hardware RAID, you don’t need to worry about the circumstance when you have plenty of SATA SSDs. They are compatible with any modern RAID controller and support relies on the type of port being used. Note that NVMe SSDs can be only used with specific RAID controller models which are equipped with M.2 slots on the card.

FAQs When Picking The Best RAID Controller

1. When do you require a RAID controller?

If you want that your PC deliver reliability and data redundancy then you require one of the best RAID controller. Occasionally, you want to backup your data and it could be extremely time-consuming. You may also find hassles when you want to restore your backups. Occasionally restoration of data can lead to data loss or failure. With the use of a RAID controller, you can prevent the risk of data loss.

RAID controller also provides comprehensive data backup and restoration in less time. Also, it can solve input/output issues. A RAID controller provides extra throughput when reading/writing data from multiple drives simultaneously.

2. What is OS and hardware compatibility in a RAID controller?

A RAID controller card must be compatible with your motherboard and operating system. The majority of them support Linux and Windows. In some cases, board compatibility may be an issue. The majority of RAID controller cards are officially compatible with only server-grade motherboards. Hence, the use of RAID on a standard motherboard will limit your choices. Before purchasing a RAID controller, make sure it is fully compatible with your motherboard and OS.

Final Thoughts

A RAID controller is an autonomous device that permits you to manage multiple HDDs or SSDs within your PC. The best RAID controller ensures that your PC runs better and secures your data in the occurrence of the loss of your drive. It increases speed, reduces redundancy, and boosts the overall performance of your system.
