Depending on the characteristics of the hard disk itself and the frequency of use.
1, mechanical hard disk, generally with 3-5 years is not a big problem. Online there are foreign machinery to do the survey, 25,000 hard disk, 6 years or so, half of the bad. The design life of the home hard disk is not shorter than three years, generally 3-5 years is possible.
2, mechanical hard disk, if you have been hooked up to use, 24 hours of continuous use as a local hard disk, life is generally less than 3 years.
3, solid state hard disk as a mobile hard disk, depending on the amount of writing. General MLC write is 3000 times, write 40G per day, 128 disk can be used for more than 20 years.
How many years can a portable hard disk last
Question 1: How many years can a portable hard disk last? Wrapped up in a dehumidifying bag and kept in light insulation, at a temperature of 26+-30%, with humidity not exceeding 50%, and most importantly away from magnetic fields, it can be kept for about 20 years, this is theoretical, and in fact I personally feel that as long as the magnetic field does not change, 50 years is not a problem, because I have an old desktop, 17 years old, as usual, it's normal to turn on the computer.
Question 2: Mobile hard drives can generally be used for a few years will not be bad careful use is not easy to damage, I have a piece of Seagate new Ruibin, has been used for about 8 years, and now also very good ah. I've been using it for about 8 years now, and it's still doing very well.
Question 3: How long is the life of a portable hard disk? First of all, to correct the owner of a mistake, Samsung is not the production of mobile hard disk. He is only authorized to commission the production of other companies, also known as genuine Samsung!
1, life: and the number of times you use by a direct relationship between the general life of the hard disk is 20-30 million times a day, once a day, you can't finish your life ah (according to his theory ah) but the actual know, as if it can't be used for such a long time. May be caused by a lot of reasons (external damage, the use of harsh environments, mobile hard disk placement is not smooth, defective itself, and so on it)
2, data security issues: he broke to see how bad, not the hard disk itself storage part of the damage, repaired on the OK, if the storage part of the problem, which will be a problem, although now there are companies to do hard disk data recovery, but the first is not The first thing you need to do is to get the hard drive back on its feet. 100% success, even if it is successful, there is a response rate, that is, there may be a certain part of the recovery can not be recovered.
Stare, how to do: this approach is not particularly much, others I do not know ah, I am the most important content carved into a CD-ROM, in case of loss. (Data loss is not only hard disk bad only appeared, viruses, misuse, relatively large external forces, into the water is estimated to be unlikely ah, partition .... (Data loss does not only occur when the hard disk is bad, viruses, misuse, external forces, water is unlikely to ah, partitioning and so on will cause data loss.) Otherwise there is no good way.
4, virus: If you say "I do not fall, save good, and never lend, they want to use on the plug, use the end of the take out and put away" that first down to the local hard disk, and then antivirus (remember to upgrade the antivirus software) and then deposited into the mobile hard disk, it is estimated that the chances of poisoning is much smaller. If poisoned, in general, you can use antivirus software to kill (most of them) If you can not kill, it is best to find out what virus is in the first to see if the special tool to kill the role, if it is not yet possible (estimated that it should be possible), delete the files infected with the virus. If it doesn't work, you can delete the infected files.
Question 4: How long does a mobile hard disk generally use to replace if normal use (no bumps or circuit damage) use 5-7 years no problem, my two 160G mobile hard disk (assembled) from 2008 to the present is still in use, and some brands of mobile hard disk will suddenly go bad, I repaired two Seagate mobile hard disk (1 1T, 1 500G), basically are I have repaired two Seagate mobile hard disk (1 1T, 1 500G), basically is the circuit failure of the hard disk box, and the hard disk inside is not a problem, inside the Samsung disk. So it's better to buy your own box plus hard drive assembly, I've purchased disks+boxes for other people from a certain treasure to assemble more than 10 pieces of mobile hard disk from 500G to 1000G, all no problem.
Stronger box recommended storage bus PD2500 (thicker), very fast, connected to the SSD speed up to 450M / S or so. Cheap have plastic shell of the Akathis FA-06UUSB3.0, the speed and the above is about the same. USB interface recommended to buy the kind of connecting cable both ends are the same, usually do not have poor contact problems.
Question 5: How many years can a portable hard drive for computers generally save data? Generally speaking hard drive if there is no accident data can be saved for more than five years, as long as you use correctly, no accidents, is not easy to lose the data, now the serial port is cheaper, 160G, more than two hundred, hard disk box more than forty Dongguan Weigu laptop repair center
Question six: mobile hard drive can be used for about how many years do not vibrate, do not read and write in the sudden pull out, mobile hard drive life should be higher than the life of the hard disk of the desktop, after all, the mobile hard disk will not always be in use.
Question 7: How long can I store data on a portable hard drive? It is best to buy two 1T hard disks, one of which is generally not used. Data 2 hard disk are prepared a copy. One of them has been used for many years, and then buy a new hard disk, the usual hard disk not used to copy the data. If the hard drive is not used inside the information can be saved for at least 500,000 years, just a few decades after the mechanical hard disk has been eliminated, even if the hard disk is broken, but the data on the disk can be recovered. CD-ROM, then only the gold disk can be saved for 100 years theoretically. Other CD-ROMs vary from 2-20 years. The CD-ROM is divided into green disk, blue disk, gold disk and so on many kinds of it. Even if the hard disk is broken, the information on the disk can basically be recovered. If the disc is oxidized, it can not be recovered. Hard disk is bad on the head drive, the disk information is permanently stored, you can find manufacturers to recover. In order to avoid disclosure of the information on the disk, the general military industry is directly knocked into pieces and thrown into the safe.
Question 8: Are portable hard disks easy to break? How many years can I use it if I take good care of it? Mobile hard disk is easy to break because the mobile hard disk plugging and unplugging times tend to be more, the hard disk will need to be many times to start and power off, and these two actions on the hard disk's life expectancy is a greater impact. There is also an easy to cause damage to the mobile hard disk is the supply voltage is insufficient, if the USB port supply voltage is insufficient, often cause greater damage to the mobile hard disk, so when using the attention of the best mobile hard disk directly into the USB port on the computer, rather than plugging into the USB extension cable or USBHUB, buy USB cable, also pay attention to buy good quality, these all affect the life of the mobile hard disk. Life expectancy. It is best to buy a portable hard disk that can be powered separately. When powering up a portable hard drive, be careful not to drop it suddenly, and it's best not to move it around, as this may cause the magnetic head to scratch across the surface of the disk and cause bad sectors.
If you take good care of it, you'll have no problem using it for five years. But if the power supply is often insufficient, two years will almost be no good. When you buy a portable hard disk, make sure you buy a model with a good reputation.
Question nine: how long can a mobile hard disk generally use mechanical hard disk life than flash memory to get more, but a fall on the play, do not fall, do not often run under high loads, 100 can be, but then I do not know that there is USB did not have to
Question ten: how many years can a mobile hard disk generally use! What is his life expectancy! Electronic products generally can not estimate the life of 9 years of a few G hard disk I still have to use more than ten years just bought a month or two of the 320G Cool Fish bad also have these all depend on luck and the use of the environment
Satisfied with the adoption
Generally, the life of the mechanical hard disk in the 3 ~ 5 years, solid state hard disk in more than 20 years, regardless of which, the use of 8 ~ 9 years is still possible.
On the cost-effective choice of mobile hard disk: Seagate, Western Digital, Samsung and Toshiba are good, Samsung has been acquired by Seagate. Quality are more reliable.

Factors affecting the lifespan of a mobile hard disk
Moving a working hard disk: When a mobile hard disk is followed by a computer, do not move it randomly, as it may accidentally cause the head to hit the platters and cause damage!
Sudden shutdown: When a portable hard disk starts to work, the internal part is usually in high-speed rotation, and sudden shutdown of the computer's power supply may result in damage to the hard disk due to violent friction between the magnetic head and the platters. So only turn off the power after the shadow disk indicator stops flashing and the hard disk ends reading and writing!
No regular anti-virus: Nowadays, the primary target of computer viruses is the data storage base, so you have to regularly anti-virus for your removable hard disk! When carrying out anti-virus, it is recommended to save the data backup, in order to prevent the disappearance of data oh!
Circuit board damage: Take the mobile hard disk, to avoid indirectly touching the circuit board, because the circuit board is connected to the computer and the hard disk of the important exit Oh! So avoid putting it in a dusty or humid place!
No protective cover: It is recommended to use a protective cover on the outside of the portable hard disk to wrap it up, so that not only can prevent dirt, but also protect the circuit board of the portable hard disk!
No careful use and storage: the biggest taboo to use it is careless use or placement, especially careless fall, of course the life is not long!

How long does a 1TB portable hard drive last?
The theoretical life of a hard disk is about 30,000 hours, and if it is used normally for 8 hours a day, it can be maintained in the normal range of about 5 years.
The service life of a hard drive is very much related to the environment and usage habits. When a hard drive is in operation, the heads and platters are spaced in millimeters apart, and any vibration may scratch the platters. So you are going to use it for mobile use, which will inevitably shorten the life of the hard disk than fixed use. Unless you use it carefully, and most of the mobile hard disk's are made with cheap platters, because with the hard disk case on the outside, you can't see what brand of hard disk is actually inside, further increasing the risk.
How long does a portable hard disk last and how do you use it properly?
The lifespan of a mobile hard disk is usually about 8 years, with shorter periods of 2-3 years and longer periods of 10 years or more, depending on the quality of the drive and the environment in which it is used.
The correct use of mobile hard disk:
1, mobile hard disk partition not more than 2.
2, the use of 200 yuan box below the best mobile hard disk are not inserted in the machine long-term work, mobile hard disk is used to temporarily exchange data, not a local hard disk.
Compared to the laptop built-in, mobile hard disk inside the laptop hard disk at all times work in harsh environments, should try to shorten the working time.
The correct way to use a portable hard drive is to use the local hard drive to download data and then copy it to the portable hard drive, not to hang on to the machine and download it all night.
3, do not give the mobile hard disk to organize the disk fragmentation, the method of organization is to the entire partition inside the data are copy out, and then copy back.
4, mobile hard disk can not be recognized or copy will be disconnected how to solve?
(1) Do not use usb extension cable, the quality of this cable is generally not very good, will make usb data synchronization error, so that the mobile hard disk can not work properly. Do not use the front usb port on the chassis, try to plug the mobile hard disk into the original usb port.
(2) Eliminate your poor quality usb hard disk case and replace the poor quality data cable with a high quality usb cable with shield.
(3)Poor usb interface compatibility, non-intel chipset motherboards sometimes have poor usb compatibility problems, the only way to completely solve this problem is to buy a pci usb2.0 card.
5, properly protect the mobile hard disk. Do not drop it, take it lightly; pay attention to the temperature, do not overheat; dry and waterproof, first back and then pull out.
Expanded Information:
Some of the 2.5-inch removable hard disk is no The power switch, only a USB cable, if you force off the power, at this time, the hard disk may still be rotating, which is equivalent to the computer is in use, a sudden power outage; this will cause damage to the hard disk.
The solution is: in the case of completed or no read-write, copy, reproduction operations click on the windows desktop in the lower right corner of the "Safely Remove Hardware" icon to select → Stop button → click "Yes" and wait for 3 to 5 minutes! The hard disk will stop spinning automatically without any read/write operation.

The average lifespan of a portable hard drive is about 1 year. >How many years is the typical lifespan of a portable hard disk?
2-5 years, this life can not be assessed, generally not commonly used 5 years is almost, my Samsung hard disk because of the usb power supply is not enough power to burn a moment, so there are a lot of accidents, end-of-life hard disk is almost no, there will be a variety of accidents, my friend's hard disk can not be more than 5 years, are generally about 3 years finished
