And there was a whole glorious epoch in electronics which did rely on keeping vacuum "in". You should have some fond memories of that. That doesn't mean that Seagate didn't botch the implementation, perhaps especially in your batch, mind you. This folks [1] do some assessment three years after they started having helium drives in their mix and the results are not as clear cut as yours. I tend to trust them, since as a cloud storage provider, they go through more hard drives in a year than we both could have, had we started at the beginning of our lives. The cool part about them is that they keep a tab on their failure rates and /publish/ them, for all of us to see.
