For those who have gone through such events in the past, what can one expect in terms of long-term impact...should we expect some premature component failures? Does anyone have any stats to share?
Realistically... you had a single short-lived stress event. There are likely to be some number of random component failures in the future. It is unlikely that you will be able to attribute the failures to such a short lived stress event of that magnitude -- there might on average be a small increase over normal failure rates. The bigger concern, may be that /a lot of different components/ could have been subject to the same kind of abuse at the same time: including sets of components that are supposed to be in a redundant pair and not fail simultaneously. I wouldn't necessarily be so concerned about premature failures --- I would be more concerned, that you may have redundant components that were exposed to the same stress event at the same time; now the assumption that their chances of failure are independent may become more questionable --- the chance of a correlated failure in the future might be greatly increased, reducing the level of effective redundancy/risk reduction today. That would apply mainly to mechanical devices such as HDDs.
