RAID array is suggested by Professor D.A Patterson from Berkeley of California University. It is called "Redundant Arrays of Inexpensive Disks". The theory of it is to build disk group in array way, and the design of data arranged dispersedly promotes data security. We can create dynamic volume in dynamic disk with dynamic disk manager by gathering several inexpensive, small capacity and highly stable disks together to form a large capacity disk. Thus multiple disks together promote the whole performance. It saves data on each disk separately. RAID array employs parity check so that when one disk breaks, computer can also access corresponding data in other disks. In dynamic disk, RAID array has fault-tolerant function, and promotes data backing up function to ensure data security.
Advantages of RAID array
RAID array has a lot of advantages, especially its high data transmission rate and fault-tolerant feature. The following are two advantages of RAID array: 1. Low cost, low consumption and high data transmission rate: in RAID, multiple disk drives transmit data at the same time, and all these drives are logically one drive. Therefore, RAID array enjoy a rate of several times, dozens of times, or even hundreds of times faster than single drive. This is the initial problem that RAID solves. In the past, CPU grew fast, but data transmission rate kept low. To solve the contradiction, RAID was born. 2. Fault-tolerant: common disk drive does not have this function, so RAID is in need. The fault-tolerant function of RAID is based on the hardware fault-tolerant function of each disk drive. So it provides better security. Many RIAD array have perfect mutual examining and restoring feature, or even directly mutual mirror backup. Thus fault-tolerant function of RAID is promoted a lot and stable redundancy of system is also improved.
Manage and partition RAID array with dynamic disk manager
MiniTool Partition Wizard is a powerful disk management software. It can manage partition in basic disk as well as dynamic volume in dynamic disk. With MiniTool Partition Wizard you can create all kinds of volumes in dynamic disk, such as mirrored volume that has great security.
This is the main interface of MiniTool Partition Wizard. Let's take creating a mirrored volume that has RAID 1 performance for example. Click dynamic disk and then click "Create" button in toolbar.
In this "Create Volume Type" interface, choose the type of volume "Mirrored" and then "Next" button to start creating. MiniTool Partition Wizard has prompts for every step so that the operation can be very easy for us. During creating, we can set which disk we need and the size of volume and so on.
Through this introduction, we can get to know the simple operation of MiniTool Partition Wizard and the comprehensive dynamic disk management functions of it. Please visit the official website of MiniTool Partition Wizard for more information about it: https://www.partitionwizard.com/.
