This article mainly introduces how long the writing life of the solid-state hard disk in the computer is, and it has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take a look at it with you.

The write life of a solid-state disk is about [10-20] years. For a 120g solid-state disk, it is necessary to write 120g files before it is considered to be [Phand E]. The average user can use it normally, even if he writes 50g per day, it can be completed once every two days on average, and 3000 [Pmax E] can be used for 20 years.

The write life of solid state drives is generally about 10-20 years.

Solid-state flash memory has a limit on the number of erases and writes, which is why many people criticize its short life. A complete erase of the flash memory is called an one-time Pmax E, so the life of the flash memory is measured in Pmax E. The lifetime of 34nm's flash memory chip is about 5000 Pmax E, while that of 25nm is about 3000 pm E.

With the improvement of the SSD firmware algorithm, the new SSD can provide fewer unnecessary writes. A 120-gigabyte solid-state hard drive must be written to a 120-gigabyte file before it can be counted as a Pamp E. Ordinary users use it normally, even if they write 50g per day, it can take 20 years to finish 3000 PPpkes in 2 days on average. (in practice, users write randomly rather than continuously, so there is a higher probability of bad channels during their service life).

In addition, although each sector of a solid-state disk can be erased and written 100000 times (SLC), some applications, such as the LOG record of the operating system, may read and write a sector many times, in which case the actual life of the solid-state drive remains untested. However, through the management of the storage unit by the equalization algorithm, its life expectancy will be extended.

The SLC has a write life of 100000 times, the lower-cost MLC has a write life of only 10, 000, and the cheap TLC flash memory has only a pitiful 500-1000.

Extended data

The solid state hard disk with TLC particles has an erase / write number of about 1000 SSD E. if we write 10GB data to Yingchi ONE 120g SSD every day, then the life of SSD is equal to 120GB*1000/10/365=33 years.

Generally speaking, before the solid state drive is completely broken, there is still a chance to enter the protection mode to preserve the integrity of the data stored on the disk in a write-protected state, thus giving the user the opportunity to make a final backup. The following figure shows the SMART information of Toshiba TR200. ID 167is SSD Protect Mode. The normal original value is zero and can be read and written. When the flash life is about to be exhausted, the value changes to 1, only reading is allowed and writing is prohibited.

Thank you for reading this article carefully. I hope the article "how long is the writing life of solid state disk in computer" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
