What is Raid Support on Motherboard & Its Types?

RAID is a data storage virtualization technology that combines multiple physical disc drive components into one or more logical units. It was in contrast to the earlier idea of single large, expensive discs, which were highly reliable mainframe disc drives.

RAID distributes data across the drives in several ways, referred to as RAID levels/types, depending on the required level of redundancy and performance. The phrase RAID lives by a number to identify the various data distribution architectures, such as RAID 0 or RAID 1 etc.

The balance between the four main objectives: reliability, availability, performance, and capacity, varies according to the scheme or RAID level. Depending on the settings you use it for, it aids in protecting data from disk failures or improving performance. This article explains what is RAID support on motherboard.

What is RAID in Computers

The Redundant Array of Inexpensive Disks exists as RAID. In other words, RAID is a method of logically combining several disks into a single array. When used in conjunction, the idea is that these disks will have the speed and dependability of a disk that costs more money. The kind of RAID you use will determine the precise speed and reliability you get from it.

What is RAID Storage?

RAID system for pc is a technique for protecting and data storage in the event of a drive failure by storing the same data in various locations on numerous hard discs or solid-state drives (SSDs).

What is RAID Configuration?

A RAID configuration combines several storage devices to produce a single functional storage system. Adding backup drives can prevent drive failure and increase overall storage efficiency. There are numerous varieties, and yours will operate according to your chosen RAID configuration.

Different Types of RAID

Different Type of RAID

After exploring what is RAID support on motherboard. Now move to the types of RAID. There is numerous standard RAID configuration of motherboard. Here is a brief explanation of each: let’s dive in!


RAID 0 creates a quicker storage unit out of two or more discs. However, in the event of a drive failure, it offers no security. Block interleaving and software stripping (minimum two drives). For speedier operation and a lower risk of overload, data is written to each drive in turn, with each block traveling to the next available drive (striping).

The volume is not limited to the size of a single disc. Since no redundancy must offer, the system collapses if one drive fails. The quickest and most effective array type is RAID 0; however, it has no fault tolerance.


RAID 1 uses two drives to create a mirror, meaning the data is the same on both. It restricts you to the storage capacity of a single drive while still protecting your data if one of the drives fails.

Data is written similarly to both drives when drives use in pairs. By connecting to its interface controller, each drive can duplex. One drive failing does not render the system unusable. Instead, the other drive keeps running.

Two drives are now required to provide the same amount of storage as one drive. There is no performance improvement at this level in the range of options for fault-tolerant, performance-critical settings. Furthermore, if fault tolerance exists for no more than two discs, RAID 1 is the sole option.


Bit interleaving and data striping perform in RAID 2. One bite at a time, data is sequentially written to each drive. Data for checksums exist on a different disc. Since ECC includes nearly all contemporary disc drives, RAID 2 is highly sluggish when writing data to disc. They rarely use it these days.


Lever 2 is comparable to RAID 3, which is more dependable. Data striping is carried out across the drives one byte at a time. High data transfer rates must provide by using 4 or 5 discs. Parity data is stored on one drive exclusively.

The parity drive can use to rebuild the contents of the failed drive in the event of a single drive failure. Data writing is typically slower since each write operation requires parity disc access. A problem arises when two or more drives fail. Long sequential records in data-intensive environments can accelerate by using RAID 3.

To prevent performance loss from short records, it necessitates synchronized spindle drives and does not permit the overlap of multiple I/O operations.


Parity checking and data stripping intersperse in blocks. Like level 3, RAID 4 employs block data striping similar to RAID 0 and a single parity disc. Each drive in this RAID level operates independently, each drive reading a block of data. Naturally, a controller failure would be disastrous. It provides no advantages above RAID 5 and does not allow multiple concurrent write operations.


Block interleaving and data striping on all discs with dispersed check data. This configuration allows you the most capacity, speed, and protection. The sole prerequisite is that you need three drives for it to function. One drive reserves for parity, which in the event of a drive loss begins to rebuild the failed drive onto the parity drive. Two drives must allocate to RAID 5 storage.

It distributes the parity information across all discs. Hot spares can use to instantly rebuild a failing drive—the best option for multi-user scenarios where write performance is not a concern. However, RAID 5 motherboard arrays need at least three discs and, more frequently, five drives.


A map between a disc drive’s physical sectors and their logical representation by the RAID 5 extension provides a log-structured file system. Information is written in sequential physical disc sectors as it must create.


It stripped array with the same fault tolerance as RAID 1 and segments that are RAID 1 arrays. Striping RAID 1 part enables high I/O rates. RAID 1 is a good option for individuals who are thinking about it because it offers good writing performance but is a costly solution.


It implements a striped RAID 0 array with RAID 3 arrays for each segment. The fault tolerance and overhead of RAID 3 are also present in RAID 53. RAID 3 is an excellent option for individuals thinking about it because it boosts write performance, but it is pricey and necessitates identical synchronization on all drives.

How to Setup RAID 0 in BIOS?

Let’s look at the steps for enabling or setting up the RAID 0 in BIOS. Before the system can load the RAID connectivity option ROM code, the BIOS must have the RAID option activated.

  • To access the BIOS setup on startup, press F2.
  • Depending on your board model, use one of the following techniques to enable RAID.
  • Set the Chipset SATA Mode to RAID by selecting Configuration > SATA Drives.
  • Make sure Configure SATA as is set to RAID under Advanced > Drive Configuration.
  • Go to Advanced > Drive Configuration, select Enhanced for Drive Mode, and select Enabled for RAID.
  • For a save and leave, press F10.

If there isn’t a RAID option in the BIOS, check your desktop board’s specification to see if RAID is supported.

Does My Motherboard Support RAID?

Does My Motherboard Support RAID

The disc controllers on the computer’s motherboard provide RAID functionality at the hardware level. Checking the motherboard manual is the most straightforward approach to determine whether your computer can support RAID.

 If you cannot discover the Manual for some reason, you can perform a similar search on the motherboard specifications of your computer on the website of its manufacturer. You can also use programs like PC Wizard to determine the type and model of the motherboard.

There is an alternative method if you cannot determine the motherboard’s build for some reason. You can check your computer’s disc controller type.

  • Press Windows Key + R and navigate Control Panel > Device Manager to examine the disk controller. Type devmgmt.msc into the Run prompt.
  • It will launch Device Manager. Navigate to “IDE ATA/ATAPI Controllers” in Device Manager.
  • Look at the controller circuit’s family; in the case mentioned above, it is ICH7, which does not allow RAID. The RAID support meaning indicates by the suffix R in the name of the corresponding chipset, ICH7R.
  • There are different chipsets, such as the ICH10 and ICH10R, whose R suffix usually indicates whether or not they enable RAID. If the chipset name is confusing you, just Google it, and you will get the information on the webpage of the chipset manufacturer.

If your computer’s motherboard does not already support RAID, you can still set up RAID by purchasing a PCI RAID card, an add-on piece of hardware containing a RAID controller chipset. Please seek professional assistance if you are unfamiliar with your computer’s internal workings.

Does Gigabyte RAID Support Motherboard?

You can get the EZ RAID feature with Gigabyte motherboards. RAID levels 0 through 10, and RAID 5 are all supported.  You can consider it the best RAID motherboard.

Why is RAID 5 Contraindicated?

RAID 5 should not use for any business-critical data, according to Dell. RAID 5 does not provide the best data protection because it has a greater chance of running into an unfixable drive issue during a rebuild.

Is RAID Beneficial For Gaming PCs?

Only massive file transfers benefit from the RAID. The majority of individuals desire a game system with RAID 0. It improves performance but is less dependable because you don’t have a backup drive. According to the assessments, there isn’t much change, and the RAID frequently loses to a single raptor.
