The 470 was about 5.0. It seems Samsung may have tweaked the firmware algorithms slightly.
Truth it, I don't put a lot of faith in either number (100+ PE cycles, then a jump to 5444). Looking at the total writes to the total count of write sectors, you don't see much WA. Around 1.06 when I calcluated yesterday.

I'm more concerned that a SE didn't fix the profound performance drop.
