Non Linux question about hard drive lifespan

Postby Charlie » Mon Oct 09, 2017 8:45 am

I have a few second user 3.5" HDD's which I have filled with movies and other video. These drives are now full and only read from and not written to, am I right in assuming that this will help prolong their lifespan?

"Research by Google shows that disk utilization plays a very small factor in a drive’s lifespan over long periods of time." - so it doesn't make a lot of difference. Ensuring the discs are kept cool and avoid physical shocks is the biggest factor.

Cant remember what was it 90% full rule to keep seek times down? Above that % seek times can wear a drive down quick.

Thanks, I thought the writing wore the drive out most. I suppose if I back them up there's no worries anyway. :wink:

Platter disks are probably designed for a lifespan of 3-5 years....

The HP tower computer I'm typing this message on has the original two, 1 TB 7200 rpm platter type Western Digital hard drives that came with this desktop computer I bought brand new in May of 2010. They're both still quiet when working and haven't given me any problems (knock on wood) after 7 years of constant use.

I have always figured 3 years for replacing a drive but I now have one that is pushing 6 years with no problems. The key, I think, is keeping them cool (35 C right now on my oldest drive) and providing good clean power via UPS. I also have been running my main system 24/7 with very few power downs.

I had figured that my oldest drive would give up several years ago but I am still waiting... When it does go I will be ready.

I do not know if read only will prolong HDD lifespan. The platter motor spins regardless. If you are not sure then it is time to copy...

I've always been bemused by the fact that the external HDD I use for back up always seem to die well before the internal main HDD I use. That's in decades of PC use across OSs - apple, windows and now linux. Admittedly I haven't had an HDD die under linux yet but that's only been slightly over a year of being linux on all my home machines.

My previous internal hard drive (WD, 5400rpm, 80gb) lasted 14 years before starting to fail...according to diagnostics, 43500 hrs of works in total approximately.

Lots of answers there to think about. Thanks for the replies. Can't imagine why used 2TB HDD's are so expensive given their limited lifespan. I know they can be rebuilt though.

While it is prudent to refresh important drives every about 5 years or so I have to say that in the 30ish years I have been using computers with hard drives I have only had a single drive ever mechanically fail on me and I have seen hundreds of 10 years old PCs running just fine with their original hard drives.
i would imagine HDDs in laptops would last a much shorter amount of time.

Really is no set answer to this, seen it mentioned the rule of thumb would be 3-5 years, as said InkKnife have seen hard drives easily last a decade or much longer, the drive in this second hand ancient Dell Inspiron 1545, is going on a decade and seems to still be going strong. Different operating system platforms are better or worse on hardware, gnu/Linux is known to prolong the life of hardware components vs window$, which I believe is intentionally designed into their OS, to prematurely wear out and require replacement of major system components. Also obviously would have to make a difference in who makes the drive = the quality of the drive and it's manufacturer.

Some brands (ie: Seagate ... according to research findings and opinions of nixers I respect) are known to have a much higher rate of failure or premature failure. Which yeah ... is only common sense, a high quality component, by a high quality manufacturer is almost certainly going to last longer than the opposite. Really don't think there's any way of knowing, outside of research quality brands and relying on quality components. Drives generally have built in diagnostics now, which can be used to assess it's overall health and warn someone of impending drive failure. My general take on it is ... use it until it fails but keeping important data backed up elsewhere is always just a good practice regardless.

Yup. I know about that. I'm not thinking that sharing a bit humor is problematic.

A very interesting article.
I wonder if there is a greater impact on certain parts of the earth's surface where the atmosphere is thinner e.g. where there is a hole in the ozone layer?

Are there any stats to compare Australia with the US?

Re the original question... back in the late 80s, hard drives had a lifespan of less than a year in desktops. I went through a few in those days.
I think the introduction of UPS and filtered power supplies helped a lot.

That said, I believe every laptop should be based on SSD, as it is daft to have mechanical drives shaken and banged around while on the road.
