My last two blog posts were about expected drive lifetimes and drive reliability. These posts were an outgrowth of the careful work that we’ve done at Backblaze to find the most cost-effective disk drives. Running a truly unlimited online backup service for only $5 per month means our cloud storage needs to be very efficient and we need to quickly figure out which drives work.
