What Small Businesses Need to Know About Hard Disk Failure
Let’s talk about the behind-the-scenes drama of data storage – yeah, those unpredictable hard disk failures that can turn your digital life upside down. But hold onto your tech hats, because Google’s study is here to spill the tea on what’s really going on.
The Surprising Truth about Temperature!
Despite what most believe, high operating temperatures aren’t the worst things to happen to your system. Disk failures are more common in LOW temperature environments.
Google found that tracking four specific SMART counters (scan errors, reallocation count, offline reallocation, and probational count) were clearly associated with subsequent hard disk failures. They found over HALF of failed drives in the sample of 100,000 disk drives showed no problems in these categories before failure.
Does Age Matter?
This is one thing Google could not pin-point in their study. There seems to be a slightly higher failure rate during the first three months. Disks that survive this burn-in period are then uniformly reliable for around a year. The manufacturer of a three year-old drive has a bigger impact on reliability than the fact that the drive is three years old. Unfortunately, Google was unwilling to share WHICH manufacturers they found to be the most reliable.
While refraining from disclosing the most reliable manufacturers, the study’s implications emphasize the imperative of robust monitoring and data management practices to mitigate the potential risks of downtime and data loss, crucial in today’s landscape where data integrity is of paramount importance.
