For a 1TB drive, so a modern fancy drive with cache and best NAND gets 1200 cycle warranty from manufacturer nowadays compared to 10K for the worst NAND flash in 2008.

and the only way to let drive know that some space is free without trimming are hacks I described above (zeroing/secure erase, smaller partition, hpa).
