Is it appropriate to purchase an SSD rather than an HDD? ...

Backblaze, a cloud storage and backup company, has revealed the long-term reliability of SSDs and HDDs, when used as boot drives.

The second edition of the Backblaze drive statistics report (opens in a new tab) based on storage hardware deployed across the business''s data centers, shows the annualized failure rate (AFR) of HDD boot drives is roughly twice that of SSD equivalents.

SSD longevity is accentuated particularly after the fifth year of usage, when 3.55% of hard drives suffer a failure, compared to only 0.92% of SSDs.


Although the data from Backblaze is indicative of performance in one context and cannot be used as a measure for SSD and hard drives that are non-functional, the company believes it is sufficient to draw appropriate conclusions about both types of storage devices.

SSDs are more reliable than HDDs, at this point, if they are utilized as boot drives in our environment. This is a testament to our anecdotal tales and educated guesses made by our readers in the past year, according to Backblaze.

According to the company, SSD failure rates are expected to rise dramatically after the fifth year of use, following a similar pattern as hard drives. For example, by the eighth year, HDD boot drives have a AFR of 6.41%.

According to the company, SSD failure rates will soon rise. It is also possible that at some point the SSDs might strike the wall, perhaps when they begin to reach their media wearout limits."

With this in mind, the business, which deployed SSD boot drives at an all-time high for the first time in 2018, will closely monitor the signs of a fall in AFR, which is expected to be revealed in the next year report.

Due to the decline in SSD capacity, a combination of performance advantages from a speed and reliability standpoint, there are only a few reasons to choose a hard disk drive, particularly to use as a boot drive.

The new figures from Backblaze might just be enough to raise the scales for organizations considering making the move themselves.
