Mode features simplicity and does not require complex and expensive controllers. The RAID 0 mode requires at least two hard disks, and the final storage capacity is the sum of the two hard disks.

RAID 10 (also called a raid 1+0 or mirrored stripe) array combines the functionality features of RAID 0 and RAID 12 to provide high-performance, fault-tolerant disk input/output operations. In RAID 0, read/write operations execute

Terms RAIDAn independent redundant disk array is a storage term. to improve performance and reliability, multiple disks are combined, which is a storage unit from the outside. the detailed introduction to RAID is not within the scope of this document; Wikipedia article "RAID" provides better content.

In Linux, how does one set RAID 10 to ensure high-performance and fault-tolerant disk input/output? (1) RAID 10, also known as RAID 1 + 0 or image strip) array combines the features of RAID 0 and RAID 1 to provide high-

Data security is one of the most important issues in the use of computers. Generally, Hard Disk Mirroring technology is used in the server environment to achieve dual data backup. We can also use this technology in Linux. In Linux, Raidtools can be used to mirror not only two hard disks, but also soft RAID 0, RAID 1, and RAID 5. It is soft

Data security is one of the most important problems people use in computers. Typically, a hard disk mirroring technique is used in a server environment to achieve a dual backup of the data. Also, we can use this technology in a Linux environment. In the Linux environment, the use of raidtools tools, not only can be two hard disk mirroring, but also can make soft RAID0, RAID1, RAID5. Said to be soft raid, because the
