The Internet is bad.
In a sense. They’re also fancy-pants enterprise drives rated to be able to last over a million hours.
Drive failures follow the old “bathtub curve”. You get the lemons that fail when they’re brand new – that’s one side of the curve. Then for several years, they fail at a consistently low rate. Then once they start getting really old, the failure rate goes up – giving you the other side of the curve.
True, these are probably closer to the “old age” side of the bathtub curve. But GHD is pretty good about honoring their warranty. Back stuff up and you should be fine.
My daily trickplay task finished in 1 minute after the update. So apparently not.
