What is the average lifespan of a hard disk?

What is the average lifespan of a consumer-grade solid state disk?

  • Answer:

    The easiest way to figure this out is to look at the warranty that you are offered with the product. If the warranty provides 1 year of protection, then you should at the very least expect a 1 year useful life. When companies calculate the cost of a warranty, they make sure that almost all the products that go out will probably (95%+) survive the warranty period. They then double that cost of replacing damaged goods to the company as a margin of safety before placing all of it into the wholesale price of the product. The products may last much longer than the warranty, especially if treated with care and if they are well maintained, but the standard warranty length is a decent lower bound. Looking at the markets, SSDs can last anywhere from 1 to 5 years, depending on the device, technology and manufacturer.

It’s a difficult question to answer because estimating an http://owerdatarecovery.com/hard-drive-recovery/ssd-data-recovery.html’s life requires taking a whole lot of factors into consideration—type and amount of NAND used in the drive, overall write amplification, read/write cycle, and more.Check this article for more details cause these guys tested the lifespan of SSDs.

That depends on the technology used. Run of the mill from a few years back may start to fail in the first year of moderate use and just slowly cover it up with degraded performance for 2 - 3 years. After 5 years you will notice the difference, or it may even stop working. Under heavy load these numbers are worse. Samsung’s 3D VNAND is supposed to change the wear problems significantly. They give endurance quotes of 10 years for 40 GB R/W daily. That workload may seem large or small given your application, but it gives a realistic expectation. I have had a few of these in moderate use for years and have not seen a significant change in performance yet.I think if you have a read heavy workload, most modern flash drives will last 5+ years. You may start to see the tip up in failures slightly before or after depending on the technology used. As your workload shifts to writes, the number of years goes down quickly. If you are constantly rewriting the whole drive I would expect less than a year. Spinning media still has a use in these cases, although the new shingled recording techniques for higher densities there are spoiling that party.
