Aside from the die shrink, Micron has addressed the glaring issue we noted in our M550 review - that issue being the sharp falloff in write speeds in lower capacities of that line. Their solution is rather innovative, to say the least.
Oh, this is cool. This sounds like a much-improved version of the EVO. We better see 25%, 50%, and 75% full benches when they launch though. I am a bit concerned though. Will the controller automatically switch to MLC mode when idle, or will it need to reach a certain capacity first?

It switches to MLC mode when 50% capacity of total available space is used, eg: On a drive with 256 Gb free of 512 Gb, it will switch to MLC mode when you hit 128 Gb of written space in one continuous write.
Background garbage collection will normally take care of things, allowing you to achieve SLC write speeds virtually at all times except if you're running the drive at 100% capacity at all times, or doing long, sustained writes (such as writing a movie to it).
Sounds like this drive needs overprovisioning much more than others. (Except SandForce!) I can't see it staying in MLC mode until exactly half is left unless you're doing sustained writes. It would need to switch in the background before that.

Actually, thats sorta how OCZs performance mode works.
DWA actually dynamically switches between MLC and SLC modes, you can have SLC like writes even when near full
