How Long Do External Hard Drives Last – 3 to 5 Years
External hard drives have many uses. Can you use it forever? Definitely, the answer is no. How long do external hard drives last? This mostly depends on how you use it and other factors like configuration, brand, size, and environment. The average external hard drive lifespan is about 3 to 5 years, provided that no physical damage occurs.
How do these factors affect external hard drive lifespan? Let's see them one by one.

Configuration
External hard drives are mechanical – using a mechanical arm with a read/write head to move around and read information from the right location on a storage platter – and its lifespan mostly depends on the wear of the mechanical structure.
Owing to the moving parts inside of external hard drives, a slight knock or drop can cause a great deal of damage.
Brand
Similarly, the brand of drive also makes a difference. The most famous hard drive brands are Seagate, WD (Western Digital), Toshiba, and Hitachi (acquired by WD in 2012).
Toshiba and WD external hard drives are quite good; Seagate's external hard drives are the cheapest, but they are less reliable; Hitachi drives are consistently reliable.
Seagate failed much more frequently than WD or Hitachi drives in Backblaze's tests (Backblaze is famous for recording and saving daily stats from the drives in their data centers).
Also based on the Backblaze's tests, you can see that Toshiba drivers are more reliable than WD and Seagate drivers.

Size
It is hard to explain the relationship between hard drive size and hard drive lifespan. One user said on www.quora.com that capacity of 4TB and 6TB hard drives are more vulnerable, with 2.06% and 2.22% failure rate, respectively; as to 3TB and 8TB hard drives, they were found to be most dependable, with 1.40% and 1.60% failure rates, respectively.
Environment
Where you place your external hard drive? The environment is quite important. Temperature, humidity, and dust can have a great influence on the external hard drive lifespan.
Different from a hard drive in a desktop PC, external hard drivers are designed to be moved around, which increases the risk of being exposed to moisture. When the wet air gets inside of external hard drives, internal components could be oxidized and a tiny amount of internal rusting can lead to a head crash.
As to temperature, too hot or too cold is both not allowed as this will cause the failure of hard disk circuit components: when the temperature is too high, magnetic media will also cause recording errors due to thermal expansion effects; when the temperature is too low, moisture in the air will be condensed on the integrated circuit components, causing a short circuit.
Dust should not be neglected. In a dusty environment, dust can get inside of the external hard drive and it will accumulate on the internal circuits and components of the disk for a long time, which will affect the heat dissipation of electronic components.
How to Protect Your External Hard Drive from Failure?
This part offers eight suggestions on how to prolong the external hard drive lifespan. It is worth bearing them in your mind.
Power on the drive when you need to use it:
This applies to both internal hard drive and external hard drive. Vertically, the more the hard drive is active and working, the more it suffers from wear and tear.
Not move it or power off your computer when it is working:

During the operation, the flying height of the magnetic head on the surface of the disk is only a few microns. In other words, when the drive is in the read-write state, moving it may cause the head to hit the disk, resulting in damage.
Moreover, do not power off your computer when your external hard drive is working. During working, it is in high-speed rotation. If you power off your computer suddenly, the head and the platter will rub each other violently.
To avoid the damage, you should pay attention to the external hard disk indicator. Fast flashing indicates that the external hard disk is reading and writing.

Many comparisons can be made between a Hard Disk Drive (HDD) and a Solid State Drive (SSD); cost, speed, data storage capacity – there's no end of areas to consider. However in this post, we'll be looking specifically at the durability of HDDs and SSDs to assess if there is any difference in life expectancy between the two data storage types.
Physical failures
It's important to firstly note that any life expectancy figures for HDDs and SSDs alike cannot be 100% guaranteed. These estimates assume manufacturer's recommended environmental conditions and do not take into consideration extremes of temperature, humidity and physical mishandling. In fact, out of almost 2000 devices surveyed between January and March 2016, at least 30% had sustained some form of physical damage to cause the media to stop working and/or cause data loss.
HDDs are electromechanical devices – they have moving parts – which generally makes them more susceptible to damage from a physical shock. However many modern hard drives, particularly those destined for the mobile device market, can withstand extremely large physical shock when the heads are parked and incorporate shock-proofing technology such as free-fall 'drop' sensors which are used to protect the heads and media even when the drive is running. Although SSDs have no moving parts and are more robust in this respect, the use of NAND flash memory as a storage medium brings with it a whole host of new complexities and therefore the possibility of data loss for reasons other than physical shock. It is therefore a myth that SSDs cannot suffer from a type of physical failure.
Loss of power
So what would happen if you just left the devices… to their own devices? Many of us would assume that if you simply did nothing and left a drive in average storage conditions (temperature, humidity, etc.) then no data would be lost, right? Well this is actually not the case; data stored on a HDD will gradually degrade as the magnetic domains representing the bits of the data change polarity, increasing the number of ‘bit errors'. But if we assume normal storage conditions, data stored on a HDD will degrade far more slowly that data stored on a SSD that uses NAND flash memory. Why? NAND flash stores data as electrical charges, which leak away relatively quickly in comparison with changes in magnetic domain polarity – it's due to the imperfect insulation within the structure of the memory itself. However with SSDs, data degradation (that is sufficient enough to prevent the correction of stored data with ‘Error Correction Algorithms') should not occur for at least 10 years if the drive is left powered down in optimum storage conditions. This timeframe does, however, depend on the type of NAND flash memory used, for example ‘Triple-Level Cell' (TLC) memory can actually lose data far more quickly – even as soon as a few months.
In fact, data loss from NAND memory can still occur even when the memory is powered. Good SSDs use a background refresh technique to restore the charge in cells that are identified as marginally retaining the data. Some areas of the NAND flash memory are reserved for use by the drive's operating code and data, known as firmware. Firmware is read every time the SSD is powered on but some portions are not re-written regularly. Although manufacturers may take steps to mitigate the effects of cell charge loss (i.e. using a less-sensitive cell charge threshold for NAND cells that store firmware and periodic refreshing of cell charges), if excessive bit errors do cause firmware corruption the SSD can stop functioning altogether.
How does this compare to HDDs? Well, every 10 years or so some of our engineers have been successfully booting up and reading data from HDD systems that are well over 30 years old - error free!
Storage of storage
What about storage conditions? Can factors such as temperature and humidity affect the retention lifetime of stored data on HDD and SSD? In short – yes – no storage media will last forever. High humidity, for example, can be a significant problem for both SSD and HDD as it can lead to the oxidisation and corrosion of metals. However high storage temperatures have a significant effect on SSD data retention; the rate of data degradation in NAND flash memory accelerates considerably with increased temperature.

For the average use of a laptop or mobile device this area probably isn't going to be an issue, but when you start looking at servers and data centres adequate media storage conditions are required to protect against drive failure (and potentially data loss) as a result of overheating or high humidity

The reality is for normal day-to-day usage in a laptop or PC, for example, you needn't lose sleep over the life expectancy of your storage media. Aside from an incredibly small proportion of manufacturer defects, your HDD or SSD shouldn't give up on you easily if you're taking care of it and keeping it away from physical hazards. If you'd like to investigate more there are many different ways to monitor the logical health of your devices; there's ‘SMART' tools to predict drive failures and software to check the wear and tear of SSDs in detail, including how much usable life it has left.
With mobile devices, there is obviously a higher risk of physical damage (dropped phone on the floor, iPads taking a bath, etc.), but with normal, everyday usage, you would be highly unlikely to encounter issues in the longevity of the storage media itself. If you're looking to store data longer-term then it might be best to go HDD over SSD, or better yet - look into the wonderful world of magnetic tape storage (yes, they're still used!).
If you're looking for further guidance on which storage type is best for your business, it's worth also checking out this article, which puts HDD and SSD technology against each other and adds the more recent ‘hybrid' storage type into the mix.
