Most impressively Seagate mention that they have shipped 1 billion HDDs in the last 4 years. That’s about 685,000 every day. Quite silly when you think about it. With all the SSD talk and marketing that the manufacturers do you’d be given to thinking that SSDs are such a reliable product (they’re not by the way). So give thought to the humble hard disk drive, how we take them for granted, and really, how few of those 685,000 a day actually fail.
