SSD Write Endurance 25nm Vs 34nm

[johnw]

I understand that it's normal, which is why I'm wondering whether Intel and Micron (possibly others) either have 1) some process to zero out factory identified bad blocks in SMART data OR 2) really good NAND processes that just generate 100% good blocks (or a process to effectively bin NAND). Only my Indilinx drives have bad blocks now, and that's because they came from the factory like that, and so I have to wonder which scenario it is.

I'm pretty sure it is (1), as I explained previously (except I don't think Intel does it, at least not the the extent that Samsung and Micron do). Assuming you are talking about the SSD level, and not the bare flash level. As I said in my previous post, I think it is done after the SSD circuit board has been assembled.

I guess Ao1 didn't see my post.
