SSD is really durable and much more stable than HDD
HDD and SSD are the two most popular storage devices today. In which, HDD (Hard-disk-drive) is the traditional form and SSD (Solid-state-drive) is a new type of hard drive in solid state.
Each type of hard drive has its own advantages and disadvantages. Therefore, deciding which one is right for you will depend on how you use your computer. However, if you are prioritizing durability and stability, an SSD will probably be a more reasonable choice.
The world's leading storage provider Backblaze has just released its latest report regarding the failure rate of hard drives (HDDs) compared to the failure rates of solid state drives (SSDs). The results can help most PC users decide whether to choose SSD or HDD for their PC rig.
Most of those who have a basic understanding of these two types of storage know that an HDD is a mechanical medium that relies on a spinning platter to read data. SSDs, on the other hand, are NAND flash based and have no moving parts inside them. Therefore, from common sense it can also be assumed that hard disks are less reliable, or in other words unstable, less durable than SSDs, because of the wear and tear of the moving parts inside the hard drive as it operates. continuity is more likely to occur.
Backblaze's experiment proves that this "anecdotal" belief is indeed true. The results of comparing the error rates between these two types of storage drives show that SSDs are generally much more reliable. The company explained the comparison methods that were taken:
The SSDs and HDDs we tested were both boot drives. They perform the same functions: start the host, record log files, act as a temporary storage for SMART stats, etc. In other words, they perform the tasks. similar service.
[..] To make a fair comparison between SSD and HDD, we controlled for the mean age of the two groups. All the hard drives in the test are about a year old.
The charts below outline the annualized failure rate (AFR) of SSDs and HDDs for 2021-22:
As you can see above, the failure rate of HDD mechanical disks seems to increase exponentially as they age, or in other words over time. Meanwhile, the AFR for SSDs seems to be stable for about 4-5 years of use.
Technically SSD hard drive uses electronic devices as memory, so when you use SSD, data will be transferred to the drive directly, on the other hand, HDD always rotates the disk to do the work. write data. Therefore, after a period of operation, the durability of SSD is also assessed to be much longer than that of HDD. That's not to mention the data read / write speed of SSD is also significantly better than HDD.
