Alas, (2-bit) MLC NAND brought P/E cycles down to 10,000 then 5,000 then 3,000.
Planar TLC (3-bit) was down to 500-1,000 until they were able to mitigate with 3D TLC going back up to 3,000.
Unfortunately, QLC (4-bit) further reduces P/E cycles (I think it's back down to 1,000).
I doubt deep sleep works same as hibernate on PCs where RAM is offloaded to flash. The flash used in Kindles just isn't fast enough for that. They're likely using TLC at best. No way they're using expensive 2GB SLC just for cache when storage on the base Kindles is just 4-8GB.
