The formation of RAID 0 is actually relatively simple. However, for ordinary users, before RAID 0 is formed. There are a lot of things that you still have to know, otherwise you can't play RAID.
The performance of 0 is worth the loss.
First, RAID 0 is best built with the same hard disk. Many people think RAID
The 0 mode can only be built with the same hard disk. In fact, this view is wrong. As long as the hard disk of the same interface can form RAID 0 mode, we recommend that RAID with the same model be used.
0. Because if the two hard drives have different capacities and different models, then the RAID array works in a backward compatible mode. Since the hard disks in the RAID array must have the same capacity, the RAID will automatically make the capacity of all the hard disks to the capacity. The lowest hard drive is on par. For example, 2 hard disks form a RAID
0, a piece of capacity is 500GB, a piece of capacity is 1TB. So the composition of RAIDO will not be 1-5TB capacity, but 1TB of capacity. And the disk speed is only improved on the basis of lower performance hard disk. In addition, because different hard disks are different in cache and hard disk capacity. Compared with the two RAID0s of the same type of hard disk, the performance is much lower. The probability of failure at the same time is also higher.
Second, play RAID 0 performance has 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, users should properly carry out some optimization measures after entering the system. For example, download the RAID management software "Rapid" from Intel and AMD.
StorageTechnology" and "RAID
Xpert", especially AMD's "RAIDXDpert", in order to open the fast read fast write function and NcQ function. In addition, RAID
The disk system in 0 mode also needs to clean up the fragmentation. So after entering the system, everyone should use the system's own defragmentation function to defragment each partition. In order to maximize the RAID performance.
0 performance. In addition, if the motherboard south bridge does not have RAID function, but rely on third-party chips to achieve RAID function, then the performance of this RAID 0 is slightly lower than the performance of the South Bridge native RAID 0.
Third, the file is backed up in advance. For users who want to build RAID0, the backup file is a thing that must be done in advance. Whether it is to build RAIDO or to revoke RAID0 in the future, the hard disk data in RAID0 cannot be saved. So if you have the need for backup files. It is best to prepare some additional storage tools.
Such as moving hard drives, burning discs, etc., so as not to lose their important files.
Fourth, non-system disk RAID
0 installation is simpler in the text. The RAID0 installation method we introduced is based on the RAID0 disk installation system. If the user owns a hard disk installation system, then buy other hard disk to build RAID.
Is 0 simpler? The answer is yes. If it is an Intel platform. Just install "Rapid" on your system.
StorageTechnology''. can manage other hard disks in the system. It is very convenient to set up RAID and cancel RAID. Similarly, AMI) systems can also install RAID in this way.
0. Just need to install AMD's RAID driver in the system.
V. RAID O is suitable for users with high speed requirements. From several RAID modes, RAID
0 is the only mode that can be applied to all disk space while significantly improving disk performance, and is suitable for non-commercial users in terms of cost and performance. But there is a certain risk in RAID 0 mode security, RAID
As long as one hard disk in the 0 mode is damaged, even if there is no problem with other hard disks, the data cannot be saved. So for RAID
In terms of 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 with a lot of important data in the computer, please Use other RAID modes, such as a more secure RAID
1 or RAID 5 with speed and security.
The USB HUBS is also known as a port replicator which is an external device designed for laptop computers. By copying or even extending the port of the notebook computer, the notebook computer can be easily connected with multiple accessories or external devices (such as power adapter, network cable, mouse, external keyboard, printer and external monitor) in one stop.
The USB C Hubs has both the functionality of a port replicator and is used to extend to a considerable degree of desktop functionality. Especially suitable for professionals, such as the need for more interface equipment. Using the laptop docking station for company, home or business presentations can also increase the ease of use and excellent scalability of the notebook. For example, consider using the UltraBay interface on the docking station to obtain an optical drive, burner, battery, numeric keypad, hard disk and other expansion functions.
The biggest use of the mini Type C Usb Hub is port expansion. As it is known to all, laptop computers are much less than desktop computers due to their own size limitations, both in terms of the number of ports and types, and sometimes it is difficult to meet the needs of users. The mini dock, on the other hand, offers multiple port extensions, like a laptop that suddenly has three heads and six arms. Some ports are most laptops do not have their own, such as serial port, PS/2, DVI, IBM dedicated floppy drive port. Some are more numerous than the body of a laptop, such as USB ports. These numerous ports allow the laptop to connect to more peripherals at the same time, improving the performance of the entire laptop and helping to increase productivity.
