Samsung CE hard drive is a more practical hard drive than ordinary PC hard drive. Ordinary hard disks will start at full speed when the power is turned on, and the instantaneous current may reach 2 amps or even higher. The Samsung CE hard drive will slowly accelerate when it starts up, and the startup current is controlled below 2 amps to support high-efficiency, low-cost power supplies. In addition, it has a real-time power saving function that allows any hard disk in the system to enter the power saving mode during non-operational periods. In this way, the system will be able to dissipate heat more effectively and greatly enhance the reliability of the overall system. Multiple hard disks are usually installed in the monitoring system. Even if a large starting current is generated at the moment of starting, the C E hard disk will not be burnt due to the unbearable power supply. At the same time, the average trouble-free running time of this series of hard disks is much longer than that of ordinary hard disks, and the stability and reliability are higher.
