They found that in the first year and a half, hard drives fail at a rate of 5.1 percent per year. In the following year and a half the failure rate falls to 1.4 percent each year. But, after three years, the failure rate jumps up to 11.8 percent per year.
Why do external hard drives fail so often?
External hard disk drives are mechanical, and they contain moving parts. This means that they will, at some point, fail. … Because external hard drives contain moving parts, this makes them more susceptible to physical damage.
How long do external hard drives last?
The simplest answer is that they can run smoothly for three to five years. This means any HDD, whether it’s external or inside of a system. Asking about the longevity of an external enclosure—a metal or plastic housing designed to cover and protect a disk drive from damage—is a different question altogether.
How often do external hard drives corrupt?
In general, during the first 1.5 years, a hard drive has a 5.1% chance of failing (which means that roughly a quarter of all hard drives will fail within their warranty period). For the next 1.5 years after that, the failure rate drops to 1.4%.
Do external hard drives go bad if not used?
The magnetic field can wear down or break down over time. So, it is possible that the hard drives go bad without use. Hard drives have moving parts, which are lubricated in some manner or form to avoid friction. … A hard drive will absolutely deteriorate if it is not been used for several years.
Can a hard drive last 10 years?
—is that the average hard disk lasts somewhere between 3 and 5 years before it will fail and need to be replaced. Some will last beyond 10 years, but these are the outliers. When an HDD fails, it will not be repairable without great expense, and so the data stored upon it will very likely be lost forever.
How can I make my external hard drive last longer?

How long will photos last on an external hard drive?
There is no way of knowing. However, it’s a good rule of thumb that a drive is increasingly likely to fail after five years or 50,000 hours of use. If you want to keep photos for 50 years, you might have to store them on roughly 10 hard drives in all.
Can external hard drives be repaired?
Generally speaking, the external hard drive errors can be repaired using CMD. What you should note is that regarding “chkdsk f: /f “, the first f should be replaced with the drive letter of the external hard drive.
Is SSD or HDD better for long term storage?
Generally, SSDs are more durable than HDDs in extreme and harsh environments because they don’t have moving parts such as actuator arms. SSDs can withstand accidental drops and other shocks, vibration, extreme temperatures, and magnetic fields better than HDDs. … Almost all types of today’s SSDs use NAND flash memory.
Is HDD good for long term storage?
Besides, when not in use, magnetic drives are more reliable for long-term storage than flash memory ones. Thus, HDDs are more capable of long time storage than SSDs when powered off.
