  1. While I agree that hard drive longevity is better overall, I wouldn't categorize it as dramatic or even groundbreaking, with the exception being SSD. I will now present a logical argument to my statements.<br /> <br /> Every hard drive made today will fail 100% of the time. It is just a matter of time.<br /> <br /> Industry ratings of Mean Time To Failure for a platter drive is about 600000 hours but a recent study released by Russia shows that the average lifespan for a hard drive is around 2-3 yrs with a low average of 1.5 years and a high average of 5 years (http://www.tomshardware.com/reviews/hdd-reliability-storelab,2681-2.html). SSD harddrives have a rating between 1.5million to 3million hours and due to SSD only being widely available and used over the last couple years, there is no reliable research on actual reliability just yet.<br /> <br /> In conclusion, I can only make two statements that I can apply across all of your users with great certainty:<br /> <br /> - It is possible for everyone here to never make a mistake that will lead to data loss, ergo human error can be eliminated (though highly unlikely). <br /> <br /> - It is 100% inevitable and certain that hardware failure will occur due to the limitations of our technology and is simply a matter of time.<br /> <br /> This underlies why I spoke up, as telling people that "RAID isn't backup" incorrectly inferred backup as a better protection of data for a cause that can be eliminated or reduced, whereas a RAID1 or any kind of redundancy related solution is a necessity to combat a problem that will occur 100% of the time.<br /> <br /> From my own experience, I have lost data 100% of the time due to hardware failure in the time before I invested and used RAID1 technology to my own systems, and 0% since (going on 3 years).<br /> <br /> Thank you for your time.
  2. "This is by far the least common reason for data loss."<br /> <br /> Wrong. Hardware failure is the most common cause of data loss.<br /> <br /> 75% of all data loss is hardware failure or human error (wikipedia), of which studies show that 40% of data loss is hardware failure compared to 29% for human error (http://gbr.pepperdine.edu/2010/08/the-cost-of-lost-data/).<br /> <br /> Google is your friend, don't spread misinformation.<br /> <br /> This is my only post.
