Big data SSD vs. HDD, the failure rate of SSD is far lower than that of HDD, the outcome has been divided

We found that SSD solid-state hard drives are replacing traditional mechanical HDD hard drives as the mainstream storage medium this year. Excluding price and capacity, SSD solid-state hard drives outperform HDD mechanical hard drives in almost every aspect. SSD solid-state hard drives have faster access speeds and increasing capacity, and their compact size is the first choice for ultra-thin computer devices. . The latter is larger in size and poor in performance, so it is only suitable for use as a “warehouse”.

But for those users who value data security , SSD and HDD hard disks need to be more reliable, so a cloud storage service provider called BackBlaze recently announced their failure rate reports for SSD and HDD hard disks in recent years.

their latest According to the report, the report stated that at the end of Q2, they had 1666 SSD hard drives and 1607 HDD hard drives. The former had 17 problems with a failure rate of 1.05%, and the latter had 619 problems with a failure rate of 6.41%. . But from the data point of view, it is true that the reliability of SSD hard disks is much higher than that of HDD hard disks, which is in line with everyone’s perception.

However, the report also pointed out that the average use time of their SSD is only 14.2 months, and the HDD hard disk has reached 52.4 months. The longer the use, the higher the failure rate. So they tested again, and this time they used SSD and HDD hard drives with a time period of about 14 months. The final conclusion is that the failure rate of SSD is 1.05%, and that of HDD hard disk is 1.38%.

Although in the last test, the failure rate of HDD hard drives is still higher than that of SSD, but the gap between the two is not very obvious.

And the normal service life of the current SSD hard disk can reach 5-10 years, and because there is no mechanical structure, it is not afraid of collision, falling, power failure, etc., so the SSD hard disk is more reliable than the HDD mechanical disk, but For ordinary users, the difference between the two is not very big, so current ordinary computers usually use a combination of SSD and HDD hard disk.
