make a real leap in read and write speed. The EIDE and UDMA controllers are very fast IDE controllers. The new UDMA controller can speed up to the SCSI controller. The top-level speed of the UDMA controller is the burst speed, but the continuous transmission speed is much slower. The IDE controller, including UDMA, is

fatal mistake, it deserves your attention. The following are some common causes of "Write cache failure ": 1. The reason for the disk drive itself. This is especially true for scsi or raid drives. Some raid drive drivers report a false message in the Windows Xp operating system where Windows Xp Sp2 is installed, telling users that "Write cache failed ". So you should install the latest driver for your disk drive. 2. Data Line reasons. Some wrong or damaged data lines, especially external USB ca

many other steps to consider, but any hardware solution that includes upgrading or purchasing new devices may be expensive. 3. upgrade from IDE To SCSI If your hard disk is an IDE drive, you can upgrade it to the SCSI drive for better overall performance. Because the IDE controller must access the CPU, CPU and disk-intensive operations may become very slow. The SCSI controller does not need to process read/write through the CPU. When the IDE drive is reading or writing, the user may complain ab

exchange mode that directly accesses data from the memory without going through the CPU. In PIO mode, data transmission between the hard disk and memory is controlled by the CPU. In DMA mode, the CPU only needs to issue commands to the DMA controller, let the DMA controller process the data transfer, and then feed back the information to the CPU after the data is transferred, which reduces the CPU resource share in a large process. The difference between the DMA mode and the PIO mode is that th

(1) The drawing context is the target object of a drawing. It defines the basic attributes of the drawing, such as color, drawing range, line width, and style. (2) A context is created through uiview. You can use statements similar to the following to obtain the current context. cgcontextref currentcontext = uigraphicsgetcurrentcontext (); (3) if you want to save the current state before modifying it, you can use uigraphicspushcontext; to restore the saved context, you can use uigraphicspopconte

In general, configuring this mode can reduce the efficiency of the system's loss due to disk reading ~ However, we do not recommend this value for WD hard disks ~ Generally 16 / 32 Yes.
