I always get initially excited about the portable external drives I see on Amazon, only to read on about failure-related nightmares from angry users. Of course this is going to happen to some degree in any make/model. But which of these products have served you particularly well or have a particularly good reputation for reliability? I would actually prefer a HDD to an SSD, even though they're more mechanically fragile than SSDs, because they seem more cost-effective and they can be totally wiped/erased when I'm finally ready to get rid of them. My old 500G Western Digital is still chugging away after 10+ years.....but it just sits on my desktop, so it doesn't see much rough-and-tumble action, temperature change etc.
