Back in 2007 Google released a research paper presenting the data collected based on their own population of 100,000 disk drives.
http://storagemojo.com/2007/02/19/googles-disk-failure-experience/
Two areas covered in their results analysis – were how effective SMART was in predicting imminent failure of drives, and the correlation between temperature and drive failure.
Surprisingly they found that lower temperatures were associated with higher failure rates (“Only at very high temperatures was there a slight reversal of this trend”)
In terms of the accuracy of SMART indicators – the Google report stated, “Our results are surprising, if not somewhat disappointing. Out of all failed drives, over 56% of them have no count in any of the four SMART signals, namely scan errors, reallocation count, offline reallocation and probational count. In other words, models based only on those signals can never predict more than half of the failed drives… even when we add all remaining SMART parameters (except temperature) we still find that over 36% of all failed drives had zero counts on all variables”
Your hard drive is the most likely component in a computer to fail (with the exception perhaps of cooling fans that get clogged with dust). It’s not a question of “if” your hard drive will die, but “when”. (Yes some people consider themselves lucky because after 4 or 5 years their hard drive seems to still be running ok – but each day using these drives, the risk of failure increases)
The best advice I’ve seen is still – “Make sure you have a current backup of all important data” and if your drives are approaching 3 years of age, it is a good idea to consider replacing them with new drives.
BuBBy said: “The best advice I’ve seen is still – “Make sure you have a current backup of all important data” and if your drives are approaching 3 years of age, it is a good idea to consider replacing them with new drives.”
Actually, most drives fail within 90 days of installation, just like most electronic items. So, replacing them when they’re three years old isn’t a bad idea…but keep the old drives around in case the new ones fail.
As for how well S.M.A.R.T. can predict a drive failure, it’s kind of hard to say because almost nobody runs S.M.A.R.T. detection software on their computer. Some motherboard manufacturers put a detection in the BIOS POST, but none seem to pause the boot process to make sure that the user sees the problem.
I recently had a drive in a RAID-5 array start to throw daily S.M.A.R.T. errors into my server’s event log, and about four days later the drive failed out of the RAID array. By then, I already had a replacement drive on it’s way to me.
S.M.A.R.T. may not alert you to all hard drive failures, but there’s no denying that it can spot some impending failures. Some is better than none in my book.
And as for backups: Anybody buying hard drives, especially with today’s capacities, really should be buying two. Ask yourself if you can stand to lose a terabyte or more of data due to a hard drive failure. If not, you need to purchase a second drive to back up the first drive’s data to. If you can’t afford two 2TB drives, then buy two 1TB drives. Seriously, all hard drives fail eventually. It may be in 20 days or it may be in 20 years, but that drive is going to fail. Can you afford to lose all of the data on it?
I forgot to mention this in my previous comment, but most of Google’s 100,000 drives were server-class drives. That means that they’re on 24/7 for up to years at a time. The drives used in a typical desktop computer are not made to the same specifications, as most desktops are turned off routinely. Shutting drives on and off tends to lead to failure more than leaving them on all of the time. Also, desktop drives typically run much hotter than server drives, as they’re not in a temperature-controlled server-room environment.
What I’m trying to point out is that Google’s experience with SCSI server drives doesn’t necessarily reflect what a typical user will see with their desktop drive. What harm is there in running software that might possibly give you a few days notice that your desktop’s drive is probably going to fail within a few days? Granted, it should all be backed up, but that’s no reason not to have this (or similar) software installed on your computer.
