Hi Mark, Yes, if a SSD could not survive writes, something is wrong with the SSD. But that was not my point. Copying about 100GB (roughly guessed) data in one go to the SSD is a use case, which is not common. And therefore possibly not taken into account by the company, which create that SSD. SSDs can create noticeable heat (mine has a minimalistic heat spreader therefore. Faster SSDs come with a substancial heatspreader). Smartctl will report problems when they are already there. I want to prevent problems beforehand. So -- does copying about 100 GB creates so much heat in the sillicone of the SSD, that it ages more than preferred? And if so, how can I prevent it by appluing other techniques to copy the data? See additional questions in my initial posting for that. Thanks a lot for any helpful advice in advance! Cheers! Meino
