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.

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.

1. 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.
