Any techie would know the term, and it’s not a game or video card, it’s the ability of a hard drive to survive drops or fall shock which is the main cause of drive failure of hard drives the world over. Accounting for more than 60% of all reasons of hard drive failure, the other 40% divided between hardware/manufacturing defects and others it is one problem that is so hard to address due to the very nature of the people who uses these ultra-high precision pieces of machines that allows us to use computers day after day after day. Some would swear by brand loyalty and some swear with the latest technological innovations like the release of the first terabyte drives and more.
G-Force is the amount of shock a hard drive can survive say in a fall as you were trying to install it. Though unknown how the manufacturers determines such events (for warranty reasons), it may be in some form of data logging and a sensor which tells the story of why they did fail. The extremely fast spinning of the hard drive platters and with the head floating a mere micrometers from its surface, any sudden jerk during a write and read operation can cause it to suddenly cause a collision between the two sending the drive into HD heaven (along with your data of course). Most manufacturers rate their hard drives for up to 3 or even 6G’s but though it is not recommended, newer drives have built in g-sensors that tells the heads to swing back into the unused parts of the hard drive platters, saving the medium from mechanical damage. Normally reserved for business class drives, the technology is fast filtering down into the consumer market where they are indeed saving gigabytes of information day by day.
But, with all the technology crammed into such a small space as the inner workings of a hard drive, they all will eventually fail so a couple of years of life is a good life for the lowly hard drive. The good thing is that they are getting cheaper and more robust all the time as we rely more and more on these technological wonders day by day.
