Backblaze is a company which operates tens of thousands of ordinary hard drives.
Their business is backing up peoples’ files so that when peoples’ ordinary hard drives crash on their own home or office computer, people can use the Backblaze online backup service to save their bacon and re-install all the files they lost.
What’s great about this company is that the reliability of hard drives is a main part of their business. So they publish their experience with the reliability of the ordinary hard drives which most people use. Because they do this, everyone can see which hard drives are truly the most reliable.
I like Backblaze.
