. RAID5 's readout efficiency is very high, writing efficiency is general, block-type collective access efficiency is good. Because parity codes are on different disks, reliability is improved. But it does not solve the parallelism of data transmission, and the design of controller is very difficult. For RAID 5, most data transfers operate on only one disk, which can be done in parallel. In RAID 5 There is

We know that the capacity of a single disk storage data is limited, in order to increase the capacity of the disk, we can combine a number of smaller disks together to form a larger disk device, which is a raid (stand-alone disk array), RAID can not only improve the storage capacity of data, but also improve the data protection function, Different levels of

1.RAID Description
RAID is an abbreviation for the English Redundant Array of Inexpensive disks, abbreviated as a redundant array of inexpensive disks.
Simply put, RAID is a combination of multiple separate hard disks (physical hard disks) in different ways to form a hard di
The disk array is made up of many inexpensive disks, combined into a large disk group, which uses individual disks to provide data with the added effect to improve the performance of the entire disk system. Using this technology, the data is cut into many sections, stored on each hard drive, even if there is a piece of damage, no data loss, and can continue to use.

Introduction
RAID, English is all called: Redundant Arrays of independent Disks, Chinese translation: Independent fault-tolerant disk array, formerly known as a fault-tolerant low-cost disk array, is now generally referred to as a disk array. The thing is presented by UC Berkeley, which can be used to integrate multip
