SSD Benifits – Reliability, Cool and Quiet, with Low Power Consumption Because SSDs have no moving parts, they can handle shock, vibration and temperature changes far in excess of traditional hard drives. That's important for desktop PCs, and essential for notebooks. Traditional mechanical hard drives spin at thousands of revolutions per minute. This takes power, and generates noise and heat. Since SSDs have no moving parts, there's no noise or vibration, and the lower power consumption helps keep things cool inside your PC.
