Discussion Overview

The discussion revolves around the life span of external hard drives (HDDs), exploring factors that influence their durability and reliability. Participants share personal experiences, insights from studies, and strategies for data backup, highlighting the variability in HDD performance over time.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Personal anecdotes

Main Points Raised

  • Some participants suggest that the life span of an external HDD can vary significantly, with some drives failing unexpectedly while others may last for decades.
  • One participant references a Google study on disk failures, implying that empirical data exists on the topic.
  • A participant shares an anecdote about a workplace experience where multiple HDDs failed after three years of continuous use, emphasizing the importance of having a backup strategy.
  • Another participant mentions a personal experience with an older system that still functions well, suggesting that usage patterns may affect longevity.
  • Some participants advocate for cloud storage solutions like Skydrive and iCloud as alternatives to physical HDDs for important data.
  • There is a consensus that all hard drives are susceptible to failure at any time, and participants recommend backing up critical information to mitigate data loss.
  • One participant notes their recent experience of losing a 750 GB drive without losing valuable data, reflecting on the unpredictability of HDD reliability.
  • Another participant shares that they have not experienced any hard drive failures in recent years, contrasting with their past experiences of multiple failures over 30 years.

Areas of Agreement / Disagreement

Participants generally agree on the unpredictability of HDD life spans and the necessity of data backups. However, there are multiple competing views regarding the effectiveness of different storage solutions and personal experiences with HDD reliability.

Contextual Notes

The discussion includes varying assumptions about usage patterns, environmental factors, and the definitions of "failure." There is no consensus on a specific life span for external HDDs, and the experiences shared are anecdotal.

Who May Find This Useful

Individuals interested in data storage solutions, those considering external HDDs for important data, and users looking for insights on backup strategies may find this discussion relevant.

I have an external HDD with a lot of information stored in it, my question is what exactly the life span of an external HDD?

Thnaks in advance.

The practical answer is "the time to failuer is usually shorter than the time you wanted to keep the data for".

In other words, if you don't have a strategy for making backups, start one now!

FWIW, we once had a situation at work where we changed workstation suppliers, and installed a few hundred identical workstations at the same time. Aboot 3 years later (after running 24 hours a day 365 days a year), they started dropping like flies with disk failures. After about 10% failures within a few months, we decided to replace all the disks - it was less disruptive to do that in a planned manner than fixing them one at a time as they crashed.
 
I have a 1995 pentium 200 on a Iwill ultra fast and wide scsi motherboard and the entire system still runs fine...even with two sound cards and a video capture system in it's slots.

I turn it off multiple times per day and have never left it on constantly.

The system drive is ide 1.6 gig and the other drives are scsi.
 
I have also many mathematical pdf files, and I have stored in a Sony External HDD but Recently I move these all to Skydrive. Skydrive and iCloud seems to be the best way to store your important data.
 
ANY hard drive can fail at any time--or could last for decades. If you have any information on a drive that you cannot afford to lose, be sure to copy it to another drive (and perhaps to a drive that you can store off-site as well).
 
In recent years, I have not had a single hard drive failure. And I work with a lot of computers. But over the last 30 years, I've had several drives fail.
 
I just lost 750 GB drive this month. Not that I have lost any valuable data.
