120GB, 240GB. 480GB, and 960GB are very strange capacities for a Marvell controller based SSD.

I can’t imagine Crucial not using a Marvell controller, but those capacities are common with SandForce and LAMD controllers, although the rated sequential read/write performance doesn’t match either of these controllers.

What was the largest 400 series Micron drive? I thought is was 512gb.
