It's certainly not the only one with SATA support. The OpenRD (based on a much older Marvell SoC has been around for quite some time. It's just a bit more expensive than the various plugs.
I suppose most (or at least: a number of them) of those chips have SATA support. It's just that the lower end product don't use it.

If sata is important then go for something designed around a NAS chip. Marvell Kirkwood, Orion and Ferroceon chips and Freescale imx51, 53 and 6 all meet this criteria. There are even some mips cobalt devices if you want a change from ARM and x86. Such devices are not always so cheap and cheerful, but some of the actual NAS products are and many are eminently hackable. This is a very useful page for NAS hacking: http://www.cyrius.com/debian/
