The compression compcache provides should help greatly with the the general bandwidth issues of any NAND based device, reducing the amount of data transferred. And because of compcache's compression, I'm assuming it already needs to re-map compressed pages -- an area that could hopefully be tweaked to re-map into neat erase block sized buffers before finally committing them to a block storage device.
