SSD or mechanical hard drive, which one do you think is more stable? Cloud storage service provider Backblaze released a hard drive failure rate report for the first half of 2023. Judging from their measured data, SSDs are more reliable than HDDs. certainly,This conclusion is still reliable. Backblaze began using SSDs in its storage repositories in the fourth quarter of 2018. On June 30, 2023, there were a total of 3,144 SSDs on its servers.
The test scenarios are also quite sufficient, such as not only loading storage services, but also storing log files and temporary storage server files. Based on server activity, the boot disk reads, writes, deletes files, etc. every day.
The company says representative statistics will be based on at least 100 SSDs sampled over 10,000 days of operation. However, you'll find that SSDs have an annual failure rate of about 1%, while HDDs have an annual failure rate of over 2%.
As storage prices continue to fall, the cost performance of SSDs has further improved, which has also made life more difficult for HDDs. Many people have said that the latter is no longer necessary. What do you think?
