In addition, Ultra DMA using bus control, the hard disk has a direct memory channel controller, can greatly reduce the hard disk in reading and writing CPU occupancy rate, the CPU occupancy rate from 92% to 52%, which is also an important role of Ultra

Since it's a device driver, let's look at how the device is described in Linux. All devices with system support are stored in the/dev directory. The device can also be a device node, and if a new device is added to the system, the corresponding node must be created under/dev. A device driver can often drive se
In today's computer system, the performance of the hard drive has become the biggest bottleneck affecting the performance of the machine. In the WINDOWS7 system with high requirements for accessories, the hard disk naturally becomes the object that needs to be optimized, and by turning on the AHCI mode of the hard
the formula "HDD single disk capacity =2X HDD Total capacity/Head count" to calculate the single disk capacity. However, the Gold Diamond Series DiamondMax PLUS9 began, the number became "0", but we know that the Gold Diamond series of DiamondMax PLUS9 is a single disc capacity of 80GB products, so the changes here will not affect our identification.Take the Gold Diamond series DiamondMax PLUS9 number "6y200m006500a" of hard disk as an example, we al
Many friends are like this, their computer for a long time and lazy to often to clean up the repair, or because of occasional poisoning, the system is not smooth or even crash. Works show these days every day on the Internet to find information, download information, make their books messy, also lazy to spend time to clean up repair, today, finally a complete strike quit.
In the face of this situation, it has always been the practice of reloading the system. But there was a problem that I never

In addition, the file names, quantities, and information files of SATA drivers attached to different boards vary, and cannot be hardcoded during integration. Only one of the three steps can be taken to succeed.

One day, I used a USB flash drive on the company's computer and copied the photos to the hard disk. As I was in a hurry to go out, I just pulled out the USB flash drive when I shut down the computer. This operation should be no different from pulling out the USB flash drive when the computer is turned on, because the m

recent SSDs prices have dropped a lot, while the HDD is showing a different trend. Although the bulk SSD price is still a bit high, but has not been able to stop consumers abandon the pace of HDD, through a few years of application, 128GB, 256GB has not enough. The budget of the hands of users will often choose to directly locate a larger 500GB or even 1TBSSD, although the price is high, but the experience is excellent. Today we will bring several 512GB capacity of SSD recommendations, for the a

No matter what chipset you are using, as long as you set the correct bi
capacity, the lower the average seek time. When the capacity of the single disc increases, the seeking action and the moving distance of the head are reduced, which reduces the average seek time and accelerates the hard disk speed. Therefore, in the purchase of hard disk products should be as far as possible to choose the average seek time short products.
