Backblaze has been releasing an annual report of their hard drive reliability for five years now. It’s a rare look into real world performance of drives at pretty massive scale. For 2018, they had just under 105,000 data drives in operation for their cloud storage and backup services.
Howard Marks is writing a series on hard drive evolution. This looks back to times when storage media was removable, 14-inch disks were a thing, and drive controllers existed off disk. While spinning media may be losing mind share to SSDs these days, Howard gives the historical context to show just how much engineering has gone into the modern hard drive.
