SSDs don’t appear to be as reliable as many people believed. Data from Blackblaze, a cloud storage business, shows that SSD failure rates are virtually as high as hard disk drive failure rates (HDDs). They described their drive analysis for both drives, which is based on real-world use in a live setting. SMART metrics are used by the corporation to monitor the health of its drivers. They claim they had no idea why their SSDs had such a high failure rate at the time.
Backblaze defines a drive failure as either a full failure or a drive failure that is impending when analyzing drive failures. Backblaze analyzes the drives’ internal SMART stats to anticipate the latter, which include read error rate, SSD wear leveling, power-on hours, total program fail count, and more.
Backblaze displays the lifetime SSD and HDD failure rates in the first table, which dates back to 2013. As you can see, HDDs have a substantially greater failure rate than SSDs, leading us to believe that SSDs are, as we’ve been promised, far more durable than HDDs.
We can observe that the findings have changed dramatically after taking into account disk age and equating SSDs and HDDs. In terms of failure rate, SSDs aren’t far behind hard drives, with a 1.05 percent annualized failure rate compared to 1.38 percent for hard drives.
As can be seen in the data, it is true that SSDs have lower failure rate than HDDs, but they will suffer the same faith of slowing down in terms of their age. Based on their observation, age is one of the factors that will cause this failure on both drives.
