How long can SSD hard drive live?

If users used to use traditional hard disk drives as HDD, Hard - disk - drive stands, today SSD drives are more dominant. However, there is a big problem that most users care about is the life of this new type of hard drive. The question of how long an ordinary SSD will "survive" is probably in the minds of many people and we will go together to find the answer in the article below!

1. Find out how SSD drives work
2. Differences between SSD and HDD hard drives
3. Things to know when upgrading hard drives to SSDs for laptops

According to HowToGeek technology page, there has been a lot of research about the actual life of an SSD, but the results are still unclear and have not made users feel secure to choose SSD as a solution. Main replacement HDD. Currently, in the SSD market has been growing quite strongly, the capacity of SSDs is also increasing, the price tends to decrease. And the research on SSD life also gradually gained remarkable results.

The good news for computer users is that SSDs have a much longer lifespan than most users once thought, and can match HDD in terms of reliability. On the contrary, the bad news is that SSDs tend to fail after a long time of use, the cause of the error is that its life is high, not related to the number of read-write times as some previous articles. This has indicated.

From the above results, you should not be too worried about the loss of data when using SDD, by equipping a PC system to use the entire SDD hard drive for the same efficiency as HDD in terms of data storage. Data, while the access speed is much higher.

Outstanding studies on SSD life

Standard lifespan, total terabytes of writable data, and the amount of data that can be written to the hard drive over a certain period of time (for example, in a day) are the three main factors that are used by SSD manufacturers. used to evaluate SSD reliability. Each element has different evaluation methods, of course the results are not the same, so it is difficult to accurately estimate the lifespan of an SSD. We can only give a very vague time at which the storage capacity of the SSD has reached its limit, through this point the data loss capability is very high.

Tech Report's research on large brands' SSDs:

To determine SSD lifespan, the team selected six brands from major brands. Accordingly, Kingston, Samsung and Corsair high-end SSDs can "survive" after recording more than 1000 terabytes of data. While conventional drives "die" in the range of 700 to 900 terabytes, including drives from Samsung and Intel using cheap MLC memory chips, and a Kingston drive that has survived but is tested in a different way. .

From the evidence, the team concluded: An SSD of about 250GB will "hit the road" after recording about 1,000 terabytes of data, but SSDs using high-end memory chips will age. a little higher life. SSDs are larger, have more sectors and more free space to burn will definitely live longer. For example, Samsung 840 SSDs use cheap MLC chips, 250GB capacity will die at 900 terabytes, while 1TB drives will be able to stay at 3.6 petabytes.

1. Basic measurement units in computers

Google research collaborated with the University of Toronto on the possibility of losing data on servers:

The research team has shown that SSD life is the leading cause of drive failure and data loss, not read and write times. In addition, the frequency of replacing the new SSD is much lower than the HDD (ratio of about 1: 4). In return, SSDs are more likely to experience irreparable errors and bad blocks than HDD for more than 4 years of use.

Since then, a conclusion has been made: In a high-frequency working environment that requires fast read speeds, SSDs will live longer than HDDs, but often suffer from more errors. In addition, "older" SSDs are more likely to "die unexpectedly" without knowing the total amount of terabytes recorded.

Research conducted by Facebook on the lifespan of SSDs used in industrial data systems:

Mainly focusing on the impact of the working environment on SSDs, this study said that frequent exposure to high temperatures reduces SSD life. Another interesting thing that the team found is that if the SSD does not "die" after the first serious error is detected, it will live a long time longer than the lifespan of the health diagnostic software. Hard forecast.

Facebook's research identifies the frequency of reading and writing data that has a great impact on hard drive life, which is in stark contrast to Google's above study. However, it is unclear whether Facebook will pay attention to the current lifespan of the SSDs they are testing.

Conclusion Facebook suggests that SSDs will live much longer than the hard drive diagnostics software announces, because the software relies on the three factors mentioned above, and as mentioned. With different conditions, these factors lead to different results.

So how long does the SSD last?

To summarize the last 3 studies, we learned that your SSD will live so long that when you are about to dispose of the old unit to upgrade to a new machine, they will still work. Good for a while longer.

In accordance with the studies of SSD lifespan, SSDs may "die" in about 1-2 years, but you should remember that in case they are used in extreme industrial data centers large, with extremely high read-write frequency, almost 24/24 every day of the year. Furthermore, the research teams also apply very heavy tests to SSDs.

Imagine how long it takes a universal user to reach 1000 terabytes recorded on the hard drive? Perhaps this number must come within a decade or so. Even gamers, it is difficult to reach the maximum level that the manufacturer offers.

So, you can rest assured about the expiry date of the SSD. However, like other electronic components, SSDs can still "die" after an electric shock, fire, explosion, . Therefore, to prevent any worst case can happen. At any time, you can choose a reputable cloud data backup service or retrofit your computer a second hard drive, which can refer to some of the best SSD hard drives for Windows computers.
