hard disk life?

Answer 1

Rougly 40,000 hrs mtbf. or forty thousand hours is the average time before a failure in testing.

Answer 2

A hard disk is a hybrid device which combines electronics (motherboard) and mechanical (spinning platter) technologies.

Although the electronic part of the hard disk will last long on normal use, it is only as good as the mechanical component.

A few hard disk manufacturers provide information on Hard Disk SERVICE LIFE.

If a hard disk has a service life of "5 years or 20,000 hours" - this means that if a hard disk operates 24 hours a day, 7 days a week, you have to replace drive with a new one every 2+ years.

But in most cases, manufacturers only provide Mean Time Before Failure.

MTBF is a reliability analysis measured in hours representing the average amount of time that will pass between random failures for a given drive.

For modern drives, the MTBF is between 300,000 to 1,200,000 hours.

So, is it correct to say that a hard disk with an MTBF of 300,000 will last more than 34 years?

Of course NOT!

The MTBF should NEVER be a reference for hard disk lifespan.

It should be used in conjuction with the Service Life.

This means that if you replace your hard disk with an identical model every 2 years, it will last for 34 years.

Using our example, there will be 300,000 hours of accumulated hard disk runtime from ALL hard disks of the same model running within 2 years, before a single failure occurs.

Answer 3

I don't know what you want to know about a hard disks life span. I can tell you that if the reformatting is minimised and also only monthly if you must, defragging and if it is Windows, constant vigilance where spyware and viruses are concerned,a hard drive can last a very long time. Temp control is also important so make sure fans are free of dust accumulation and the vents also because temp build up is a major cause for data loss due to hard drive crashing. And also in electrical storms turn the power off at the source to take all chance of a surge damaging your system because surge arrestors have been known to not function in a time of crisis. I hope this all helps. OH and never handle a hard drive without a static wrist band.

HDD Life Pro is a small piece of software which shows you the health of your hard disk. Its not a free software but you can use it as a shareware which shall disable some options. Otherwise, download "HD Tach" from "http://www.majorgeeks.com/HDTach_d672.html" which gives you the present state of your hard disk by performing ceratin tests. Its a freeware. On an average, donot expect a hard disk to last more than 2 to 3 years. The more that I/O (Input Operations) i.e. disk read and write operations, the lesser that hard disk life. Hence, have more RAM so that most of your opeartions can be done on RAM rather than swapping data from the swap file of the hard disk.

Answer 5

Chances are that a hard drive can break when the computer switches on and off. So an always-on computer that is powered by UPS has less chances.

Most manufacturers have a mean time before failure on the technical specs. Practically it can break after a few months or after a few years so I cant give you a defenate answer...

If you want to ensure that your data is safe do backups and think about a raid solution that gives you redundancy if one hard drive breaks!

good luck!

Answer 6

What a load of crap! these previous answers!

Okay, for a start as long as you dont leave your pc on all day every day then you can at least get 6 years out of your hard drive. As long as it doesnt take and bumps along the way. Try and format or defrag your hard drive about twice every year, this takes the strain off your system. Otherwise your hard drive's life span may be reduced.

Its the same as anything else, if you look after it then it will last.

Hope this helps...

Answer 7

a hard disk can fail at any time.. it can fail within the first week you buy it, or 10 years later.. there is no specific time.
