Is failing once every 5 years really different from failing once every 1000 years? You should have disaster recovery plans anyway and configuration errors are the most likely cause of failure, not the underlying storage system.
- phonon 6y agoFor companies that have a few hundred of these running at a time, it sure does! Also, it's a 2000x ratio, not 200..., and 1/500 years vs. 1/1,000,000 years.
- votepaunchy 6y agoAWS’s claimed 99.999% ratio is 1/100,000 years. Claimed improvement of 100x in the article.
- phonon 6y agoHmmm, it said "2000x more reliable than a commodity disk drive" in the article which I misunderstood (I guess that is a comparison to a local HD) + plus my inability to do math late at night :-) Thank you for the correction!
