I can guarantee you it's not 33.000 R/W cycles - the only tech that would allow that is SLC, and practically nobody sells SSD based on SLC anymore. A few manufacturers sell highly overpriced SLC-based SD and microSD cards. Hell, nowadays you'll struggle to even find MLC-based SSDs (~10.000 rewrite cycles AT BEST). Every SSD manufacturer today uses TLC, which means 1000 R/W cycles per cell.
You're still talking about flash technology, as far as I can see... the point of Optane is that it's using this new phase-change stuff. Supposedly it would have a thousand times the write endurance, and be a thousand times faster than NAND flash (though I don't think they ever said whether it was SLC/MLC/TLC they were comparing to). It doesn't look like either promise has come true, though.
