RAID on the motherboard, what is the use of it?

The disk array controller, for example, two identical disks, can completely copy the contents of this disk to the other disk to change data in one disk, and is mostly used to save data on machines with high data security requirements. Reference.

The RAID function on a motherboard means that the motherboard supports disk arrays.

A disk array is composed of many independent disks that are combined into a disk group with a huge capacity, and the additional effect generated by the data provided by individual disks improves the performance of the entire disk system. Using this technology, the data is sliced into many segments and stored on separate hard drives.

Disk arrays can also use the concept of parity check, which can still read data in the event of a failure of any hard disk in the array, and when the data is reconstructed, the data will be calculated and re-placed into a new hard drive.

RAID (Redundant Disk Array) is a technology that combines multiple hard drives together to improve data reliability, performance, and/or storage capacity. In this case, the RAID controller that comes with the motherboard means that the feature is already built into the motherboard without the need for additional hardware. Expansion cards need to be purchased separately and inserted into the expansion card slot on the motherboard.

The benefits of a motherboard's own RAID controller include:

Lower cost: Since the motherboard already has a RAID controller, there is no need to purchase an additional expansion card. This can lead to some cost savings.

Ease of maintenance: Using the RAID controller that comes with the motherboard is often easier to maintain than using an expansion card, as all the hardware is integrated to make it easier to diagnose and fix faults.

Stable performance: Since the RAID controller that comes with the motherboard is already integrated into the motherboard, it can often provide more stable performance.

However, the benefits of the expansion card include:

Better performance: Because expansion cards are separate hardware devices, they typically provide better performance than the RAID controller that comes with the motherboard.

More advanced RAID levels of Bibe: Some advanced RAID levels, such as RAID 6 or RAID 60, may require more advanced controllers that may only be available through expansion cards.

In summary, the choice between the RAID controller that comes with the motherboard and the expansion card depends on your specific needs and budget. If you only need basic RAID features and are on a budget, then the RAID controller that comes with your motherboard may be a better choice. However, if you need a more advanced RAID level, better performance, or greater storage capacity, you may want to opt for an expansion card.

The RAID function on the computer motherboard means that your motherboard supports RAID, and here, you can set the relevant parameters of RAID.

RAID (Redundant Arrays of Independent Disks, RAID) means independent disk redundant array in Chinese, which is a technology that achieves file backup function by splitting files into multiple blocks and storing them in several different hard disks.

There are several different levels of RAID, each with a different focus or characteristics, but they all have one thing in common: they all require multiple hard drives. For example, RAID 0 requires more than 2 hard disks and the number of hard disks must be even, and it is characterized by a 2x increase in read and write speed, but if one hard disk is broken, the entire file is damaged.

RAID 1 also requires more than 2 hard disks, and the number of hard disks must be an even number, it is characterized by the same read and write speed, but if one hard disk is broken, the files will not be damaged. Reference.

It's a disk array group, that is, when you have many, many hard disks, for example, if you have 5 hard disks, "this is okay", but if you turn on the RAID function, the computer will merge your 5 hard disks into one, and you will see a disk with a large capacity, which is actually composed of those five.

RAID is the abbreviation of "Redundant Array of Independent Disk", which means independent redundant disk array in Chinese. Redundant disk array technology was born in 1987 and was proposed by the University of California, Berkeley. To put it simply, it is to combine N hard disks into a virtual single large-capacity hard disk through a raid controller (divided into hardware and software).

The adoption of RAID brings significant benefits to the storage system (or the server's built-in storage), with increased transfer rates and fault tolerance being the biggest benefits. In addition, RAID also has the meaning of pesticide brand, French SWAT team name, game proper noun and so on.

IDE is the type.

RAID is a technology that connects multiple hard disks in series.
