Storage devices are an indispensable part of a computer, such as hard disk, memory, video memory, cache, etc. do you know which of these storage devices has the longest life? In fact, many players will associate memory with hard disk in their mind, thinking that there will be a limit on the number of reads and writes, but is this really the case? Let’s discuss this topic today!
1. Memory life mechanism. At present, DDR4 memory is widely used in mainstream models. DDR is a dynamic random access memory, which does not store data for a long time, which is the most essential difference between DDR and hard disk. As we all know, the data stored in the memory is mainly provided to the CPU and serves as the data supply unit of the computing core. The amount of data flowing through each second is extremely huge, which means that although all kinds of information will be temporarily stored in the memory, the residence time is very short. The refresh frequency is calculated in milliseconds, and nothing can be retained.
Since the memory is constantly refreshed, there is no limit on the number of writes. No matter how many times the PE is, it will not have much impact on its life. This is similar to your mobile phone, which gets stuck after a period of time. After restoring the factory settings, it will become very smooth. The memory is similar to the operation of restoring the factory all the time. Only equipment aging and hardware failure can affect its service life. Data writing and erasing alone cannot shorten its service life.
2. Hard disk service life mechanism. Hard disk is divided into mechanical hard disk and solid state hard disk, and their service life algorithms are not the same. Due to internal structure problems, mechanical hard disk is easy to be damaged by collision, but if it runs in an almost perfect external environment, it can basically live the same life as the whole machine, which has nothing to do with the number of times of use. Even many antique hard disks more than ten years ago can still be used today.
Solid state drives suffer a lot in this regard. Due to the difference of flash memory particles, the most high-end SLC particles can support about 100000 reads and writes, the mainstream TLC particles are about 2000 times, and the shortest QLC particles are 1000 times. Therefore, its service life is generally restrained. Although it can not be used as an heirloom, it is still no problem in three or five years, Enough to support players to carry through the cycle of upgrading equipment.
After such a comparison, I believe everyone has a number of life expectancy of the memory module. Under normal use, the memory is difficult to break down, and the possibility of retirement is nothing more than bad use habits, human factors and their own aging. Therefore, as long as everyone uses the method correctly and takes care of it carefully, the memory will always accompany you.
