I just got my new toy in the mail today - a PCI express SATA2 host adapter which fits the mini-card slot on my Intel 510MO motherboard. This gives my Atom WHS four full-speed SATA2 ports, with the two new ports being port-expander compatible.
The MPX-3132 SATA2 host adapter mini-card is from Global American, which sells quite a variety of industrial embedded controller systems, motherboards, and accessories. I found them to be very friendly to the "hobbiest". Their part number is 1507890 and I was quoted $55.90 US for single unit quantities.
The card arrived extremely well protected.

Box in a box ...

Contents: What you get for your $56 is the MPX-3132 controller board, a driver disk, and a pair of short data cables with a matching mini-connector on one end. The card uses the SiI 3132 host controller chip, so it is the direct equivalent of the generic 1x PCIe 2-port SATA2 RAID cards available from virtually every peripheral card manufacturer.

Installation: Stupid/simple - plug it in and it works.

Since I'm not using RAID, I didn't even need the driver disk. While a device driver is required, the standard Windows new hardware update routine downloads the SiI3132 RAID driver from online and that's that. Couldn't be easier.
Thoughts and Murmurs: Once the hardware was up & running, I took a look at the BIOS and driver versions to see what (if anything) needed flashing or updating. The BIOS is two versions back - v7.5.07 instead of v7.7.03 - so anyone using this in a Windows7 system should flash the BIOS to the latest version along with updating the driver. You can also flash the BIOS if you want to use the non-RAID "Base" BIOS & drivers instead of the ones supplied with the card. Fortunately, the card uses a reference-board-compatible flash memory chip, so SI's flashing tools should work just fine.
If you add a SiI 3124-based PCI SATA2 card in the regular expansion slot, the 510MO ends up with eight SATA2 ports, four of which run at full speed and four which run at the reduced PCI interface speed. Eight 2TB drives gives you 16TB of bulk storage on a little mini-ITX Atom board. Not bad at all. If you really need more drives, a pair of Addonics port expanders will turn the two ports on the mini-card into ten (hope you have a big PSU).
Of course, we can get really silly using this setup. The PCI slot on the Intel 510MO is compatible with one and two-slot riser cards. Adding the MPX-3122, a two-slot riser, and two 3124-based PCI host adapters gives you a total of ten port-expander-compatible SATA2 ports on a mini-ITX board. At five ports per expander and counting the motherboard's two built-in ports, you suddenly have 52 (!!!) SATA2 ports to play with. Add a 2TB drive to each port and your mini-ITX Atom system ends up with over a hundred terabytes of bulk storage.
The mind boggles.
... and on that absurd note, I'm signing off.
