SSDs, especially large ones, run hot. I've been saying this all the time, but nobody listens.
Gotta make sure it keeps on running hot, too. Cold SSDs are good when they are off, else they fail to retain data (data loss). But when on, the opposite is true: they lose data if the temperatures are lower than they should be.
Be it in the sunniest summer days or in absolutely frost winter, though, I never experienced SSD data loss in all the 10 years I have been using them.
On the other hand, though, I have been utterly $&%! by failing HDDs, floppies, flash drives (i.e. USB pendrives), CDs, DVDs (no issues with BDs, though) and so on. But I also try to make sure I at least turn them on every 6 months or so, else that could be an issue.
But yeah, I can imagine in terms of temps that SSDs won't be ultra friendly. My Mac hardware old and current have been fine with them so far, though: MDDs, PBs, mini etc..
