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!
