The formation of RAID 0 is actually relatively simple. But for ordinary users, before the formation of RAID 0. There are many things that must be known, otherwise RAID cannot be used
The performance of 0 is worth the loss.
1. RAID 0 is best to use the same hard disk to build. Many people think that RAID
The 0 mode can only be built with the same hard drive. In fact, this view is wrong. As long as the hard drives of the same interface can form a RAID 0 mode, we recommend that it is best to use the same type of hard drives to form a RAID
0. Because if the capacity of the two hard disks is different and the model is different, then the RAID array works in a backward compatible mode. Since the hard disks in the RAID array must have the same capacity in the form of expression, RAID will automatically let the capacity of all hard disks to the capacity. The lowest hard drive is on par. For example, 2 hard drives form RAID
0, a capacity of 500GB, a capacity of 1TB. Then RAIDO will not be 1-5TB capacity, but 1TB capacity. And the disk speed is only improved on the basis of lower performance hard drives. In addition, different hard disks have different caches and single-disk capacities. Compared with the RAID0 composed of two hard disks of the same model, the performance will drop a lot. At the same time, the probability of failure is higher.
Second, the performance of RAID 0 has been paid attention to many people have complained about the formation of RAID
After 0, the software test found that the performance is not as high as expected, in fact, the user should properly perform some optimization measures after entering the system. For example, download the RAID management software of Intel and AMD "Rapid
StorageTechnology "and" RAID
Xpert ", especially AMD's" RAIDXDpert ", in order to open the fast read and write function and NcQ function. In addition. RAID
The disk system in the 0 mode also needs to clean up the debris. So after entering the system, it is best to use the system's own defragmentation function to defragment each partition. In order to maximize the use of RAID
0 performance. In addition, if the motherboard south bridge does not have a RAID function, but rely on a third-party chip to implement the RAID function, then the performance of this kind of RAID 0 is slightly lower than the performance of the south bridge native RAID 0.
3. Back up the files in advance. For users who want to set up RAID0, backing up files is a must do in advance. Whether it is to set up RAIDO or to revoke RAID0 in the future. Hard disk data in RAID0 cannot be saved. So if you have a need to back up files. It is best to prepare additional storage tools.
Such as mobile hard disk, burning CD, etc., so as not to lose your important files.
4. RAID of non-system disk
0 installation is simpler in the article. The RAID0 installation method we introduced is based on the situation of RAID0 disk installation system. If the user owns a hard disk to install the system. Then buy another hard disk to build RAID
Is 0 simpler? The answer is yes. If it is an Intel platform. Just install "Rapid in the system
StorageTechnology ''. You can manage other hard drives in the system. This includes the formation of RAID and the cancellation of RAID, which is very convenient. Similarly, AMI) system can also install RAID in this way
0. Only need to install AMD RAID driver in the system.
Fifth, RAID O is suitable for users with high speed requirements. From the perspective of several RAID modes, RAID
0 is the only mode that can be applied to all disk space while greatly improving disk performance. It is more suitable for non-commercial users in terms of cost and performance. However, there are certain risks in the security of RAID 0 mode, RAID
As long as one of the hard drives in the 0 mode is damaged, even if there is no problem with other hard drives, the data cannot be saved. So for RAID
In terms of the 0 mode. We think it is more suitable for users who have higher requirements for system speed (such as gamers, hardware players, and users who always feel that the computer is slow), and users who have a lot of important information on the computer, please Use other RAID modes, such as RAID with better security
1 or RAID 5 with speed and security.
