How to distinguish the old and new hard disks? I don't need to be cheated

When we buy a new hard disk, you must not be confused by its brand-new appearance. At this time, we need to see whether the built-in hard disk is new. Because now, the market is full of all kinds of fake hard disks. If we don't distinguish them, we are likely to be cheated. Next, I will teach you a simple way to distinguish the old and new hard disks.

For the novice, Xiaobian should recommend a very practical and convenient software - "efficiency data security center", which can help us detect the old and new hard disks with one click. First, download the "efficient data security center" software in the app store and update it to the latest version. Then open the software and go to the toolbox to find 'health diagnosis'. At this time, we can see "power on time" and "start and stop times". According to these two data, we can use them to judge the old and new hard disks. First of all, the power on time of the new hard disk will not be 0, because the factory hard disk will take a certain time to test, and this check time is recorded as the power on time. Therefore, the power up time within 30 hours is within the normal scope of the new hard disk. If it exceeds or even reaches hundreds of hours, it can be concluded that this is an old hard disk.

The service life of mechanical hard disk is usually calculated on an annual basis, generally 3 years or more. If more than three years, some hard disks can still be used, but its performance will decline, such as noise. The life of SSDs is usually judged by the number of writes or write capacity. Now, it is calculated in TB and Pb units. In addition, according to different types of flash memory chips, the number of reading and writing of solid-state disk can reach 10000-100000 times, and some professional level can even reach a million times. Even the shortest service life can reach 5-10 years.

Here, Xiaobian finally tells you that we should pay more attention to the use of computers at ordinary times, such as the temperature and health of the hard disk. We should always have a good grasp, so as to avoid the situation of data loss caused by hard disk damage to a large extent.
