Commercial? Ehh, not extremely expensive at least...
At the same time, don't HDDs already saturate the 360's internal transfer speeds? I still don't understand the point of adding SSDs into old consoles other than not having an HDD sticking out, since in most cases there's no clear benefit.
At one point in the future, 2.5" HDDs might be a thing of the past, having 2.5" SSDs work on a stock 360 will be a very neat thing.
