Are there any publicly available specs on the flash NAND used in these drives that might list p/e cycles? It does sound like Intel may be expecting 5000 p/e which seems kind of on the high end for 25nm from what I have read. Either it is unusually good NAND or the standard estimates I have seen of 3k/5k/10k for 25nm, 34nm, and 50nm are a bit low. That very well may be and these sorts of tests can show exactly how low they really are. It should be interesting to see how gradually the writes start failing. If wear leveling is good enough I suppose it could all happen in a very short period of time at EOL.
