>Most flash has average wear out after 300k cycles
No it doesn't. Most 1TB drives are rated for around 600 TBW, so enough to overwrite the drive 600 times, nowhere near 300k cycles. If you search for specs of NAND chips used in SSDs, you'll find they're rated for cycles on the order of hundreds to thousands, still nowhere near "300k".

Original mid-90s Toshiba "solid state floppy disk" SLC flash: 1M cycles
2000s SLC flash: 100K cycles
Modern SLC/pSLC flash: 30-60K cycles
2010s MLC flash: 5-10K cycles
Modern QLC flash: 300-500 cycles
...and I won't even get into the details of their retention characteristics, suffice to say they subtly redefined them over the years to make the newer numbers better than they really are.
