　　The disk array (redundant Arrays of inexpensive disks,raid) has the meaning of "inexpensive and redundant disk arrays". the principle is to use array method to do disk group, with the design of data distributed arrangement, improve the security of data. The disk array is made up of many inexpensive, small, stable, slow disks, combined into a large disk group, and the added effect of providing data with individual disks increases the performance of the entire disk system. At the same time, the

Once high cost performance G620 processor +h61 Motherboard became a classic entry-level platform, but with the advent of the G620 processor upgrade G630, it seems to be breaking the situation, G630 processors have better performance, and the price is equivalent to the increase of no increase in products, Therefore, the current installation of the author think that the introduction of cost-effective G630 platform is worth recommending, the following computer technology for everyone to recommend d

it is one of the keys to improve the performance of the computer. Even an old-fashioned laptop or desktop can have a significant boost in performance after replacing a solid-state drive, so if your office computer has made you feel very slow, consider replacing the solid state drive before replacing the whole machine. Seagate's Momentus hybrid hard drive integrates both solid-state and mechanical hard drive features Of course, solid-state drives are not perfect, and in addition to

, memory brand is not much, of which Kingston is the largest memory brand, followed by Granville, after the light Granville, Zhi Qi, pirate ship, Samsung, Yu-Zhan, the ten civil. 　　5, hard disk brand At present, computer hardware is divided into traditional mechanical hard drives and solid-state drives, of which solid-state drives are the mainstream of the future, speed is a traditional mechanical hard disk several times. At present, the main advantage of mechanical hard disk is large capacity

can not replace the status. Early IDE interfaces have two transport modes, one is PIO (programming I/O) mode and the other is DMA (Direct Memory Access). Although DMA mode system resources are low, they require additional drivers or settings and are therefore less acceptable. Later, in the case of higher speed requirements, the DMA mode is more efficient, the operating system starts to support directly, and the manufacturer has introduced more and more Fast DMA mode transfer speed standard. St

In fact, notebook BIOS is relatively simple, unlike the desktop BIOS has so many rich adjustment options, Acer notebook BIOS is not the same, but if the processor, or the same platform, the difference will not be very large, today we will go into the 4750 bios to see. First press the power button to display a large Acer logo There is a line below the lower right corner and a progress bar showing self test progress ↑ According to the prompts F2 into the Bios

. -r -s -T evaluates the drive's read efficiency. -T-Pinggu read efficiency for fast drive fetches. -u -V displays related settings for the hard drive. -w -x -y enables IDE hard drive into power saving mode. -y enables IDE hard drive into sleep mode. -Z turns off the automatic power-saving features of some Seagate hard drives. Hdparm Common Parameter Use example: 1, display the relevant settings of the hard disk: The code is as follows:

Volume and Weight: SSD victory 2. Noise and Vibration: SSD again, absolute mute, and HDD noise can be high and low, some enough to make people crazy, and vibration is a problem to consider. 3. Temperature: HDD Work when the highest temperature of about forty or fifty degrees, SSD to low, but this problem h

Troubleshooting for motherboard driver Exceptions: 1, the motherboard drive causes the computer to crash the breakdown Friends assembled soon after the computer recently crashes, fault phenomenon is in the operation of some graphics image processing software, whenever the processing finished save the machine will panic, which makes friends feel very annoyed, reinstall the operating system many times after the failure is still not ruled out, And the most important thing is that friends of the c
