Ordinary hard disk design work time is short, monitoring hard disk work around the clock
Monitoring often requires the continuous operation of the hard disk continuously. At this point, the ordinary hard disk and monitor hard disk are very different. Ordinary hard disk is designed for 5*8 hours of continuous work time, that is to say 5 working days, each working day hard disk work 8 hours. From this data point of view, ordinary hard drives are not suitable for continuous reading and writing over a long period of time. If they are read and written over a long period of time, they will inevitably be overwhelmed by problems; while monitoring-class hard drives can achieve 7*24 continuous work throughout the year, The average time between failures is 1 million hours. Therefore, in terms of stability and reliability, the monitoring hard disk is no doubt a winner.
Ordinary hard disk power management is poor, monitor hard disk power management is strict
Monitoring often requires multiple hard disks to be installed at the same time. If there is no good power management, power consumption and security will be hidden. The instantaneous current that the ordinary hard disk starts will reach 2.5 ampere, even higher. The monitoring of the current when the hard disk starts is controlled at 2 amps, you can use a low-power power supply, to avoid the instantaneous high current and burned. In addition, the monitoring hard disk has a power optimization function that can switch to a low-power mode when the hard disk is idle, saving power.
Ordinary hard disk cooling environment is poor, monitoring hard disk cooling environment
Monitors have different requirements for the number of hard disks, but often have several or even many hard disks. Under this background, there is a higher requirement for the heat dissipation environment. The power consumption of an ordinary hard disk is about 14.5W. If it is a host with a hard disk basically no problem, but for monitoring such an extreme environment that requires multiple hard disks, the heat dissipation problem caused by this power consumption can not be ignored. Monitoring hard drive power consumption is very low, 2TB work power <5W, natural heat dissipation is very low, the installation of multiple hard drives will not have too high power consumption, to ensure a relatively good cooling environment.
Ordinary hard drives seek fast, monitor hard drives pursue lasting stability
The biggest characteristic of monitoring is that it requires the hard disk to write continuously for a long time, but it does not have too high requirements for data reading. This point of view of the ordinary hard drive can not meet the requirements from the design. Ordinary hard disk is often a random small file to read and write in the home environment to seek speed, while the monitoring hard disk is suitable for continuous large files continuously written, with good stability.
The difference between monitoring hard disk and ordinary hard disk
With the continuous growth of the security monitoring industry, the importance of monitoring hard drives has become increasingly prominent. So, how different is the monitoring hard disk and the ordinary hard disk? Why must choose a professional monitoring hard disk? From practical applications, the differences between the monitoring hard disk and the ordinary hard disk are mainly reflected in the four aspects of power supply, cooling environment, data reading and writing and working time.
