Storage research found that SSD may not be much more reliable than HDD

The traditional view is that solid-state drives themselves are less prone to failure than mechanical hard drives because they have no moving parts. But it turns out that a new report from Backblaze shows that there are rotating disks, actuator arms, and motors in all HDDs, which may not be a big disadvantage because it is related to reliability.

Backblaze is a subscription-based cloud storage and backup service that has been running for more than ten years. Therefore, it is in a unique position to provide real-world data on drive failure rates, and it often provides statistics on its drive failures for public use.
