Look and believe

30944 hours 8000 power ons

Great?

[Enderman]

and why exactly did you make this topic...?

 

is 30k hours special or something?

Average HDD is rated at 4-5k

This one has 30

OP I think this would fit better in off topic

[Enderman]

Average HDD is rated at 4-5k

This one has 30

um, no?

average HDD is rated at 1-2 MILLION  hours

that is 1 000 000 - 2 000 000

not 4000-5000

4K hours is 166 days.

30K is nothing got a triple raid 0 of 3 WD caviar Black on little bro computer , it's runing for 36k hours , works fine.

Btw , get some real case or fan because 51°C on a drive is freaking high...

Yup, no. You're thinking of Mean Time Between Failures. Hard disk aren't rated for their MTBF. MTBF is derived from laboratory tests and it's intended to be used for comparison, not as a measure of real-world longevity. Consumer HDD models are rated for around eight hours of daily use for three to five years. There is no hard disk in existence that lasts for hundreds of years in 24/7 operation.

do you know what mean time before failure means??

 

because it literally means "mean time before failure"

 

i have seen most consumer drives reach about 100-300 thousand hours before getting any relocated sectors and errors from degradation

 

30k hours is not even close to how long HDDs last, and this is only talking about consumer drives

you need to do some research, and see how long enterprise HDDs last

lol

Take a thousand disks, test them for a thousand hours. If none fail, your MTBF is one million hours minimum. Keep at it until you get a failed drive and do the math. And there you have it. They don't test single drives for millions on hours. It's only been half a million hours since HDDs were invented! On that note, 300 thousand hours is 34 years... I have yet so see a drive that old, let alone a consumer-grade one. I find it hard to believe these drives we have now would last that long either but I'm willing to admit I'm wrong. In the year 2050.

 

Here's more info on how MTBF is determined and it's relation to drive longevity.

 

I'm not saying HDDs can't be used for years-on-end. I have old drives still in use myself. But the maximum they're rated (designed to be used daily) for is in the order of years, not hundreds or even tens of years.

lol that's not how it works at all

 

did you even do some research?

based on your flawed logic, WD could run 1000 hard drives for a few years and claim a billion hours MTBF

that's NOT how MTBF is calculated

https://en.wikipedia.org/wiki/Mean_time_between_failures

 

 

 

The first system failed at 100 hours, the second failed at 120 hours and the third failed at 130 hours. The MTBF of the system is the average of the three failure times, which is 116.667 hours. If the systems are non-repairable, then their MTTF would be 116.667 hours.

30k hours is nothing special.. I have many flavors of disks in my NAS's running well over 50,000 hours and still running fine.
