and intuitively think of circuits with no moving parts as reliable Yes. It's counterintuitive to realise that non-mechanical parts are more prone to 'burn-out' rather than 'wear-out'. I've only just got over my reluctance to entrust large volumes of data (6 TB) to SSDs rather than HDDs. But I'm still a bit twitchy about that. Time will tell whether or not my fears are justified.
