If we want to quickly improve the hard disk read data under Linux, you can do some settings under Linux, let Linux work in 32-bit input and output mode and DMA channel mode. When setting, enter the 32bit transfer mode in the Linux command interface, enter the 32bit transfer mode, enter command / sbin / hdparm -dl / dev / hda to open the DMA transmission mode, then enter the command / sbin / hdparm -kl / dev / hda to make the hard disk still maintain the above settings after RESET, and we can improve Linux's read discs to more than 1 times.
