Is there an SSD that will work with any MiniPCIe slot?

I have a Dell Inspiron 1520, and I have three mini-PCIe slots, only one used. I was hoping to add a solid state drive for some storage off my main HD. Just an area for automatic backup in case of sudden HD failure. I see alot of these cards being produced specifically for netbooks, but it looks like the netbooks bring out SATA or PATA lines to the PCIe card connector in a way that a standard laptop does not. Are there cards that have the controller on board and use a standard PCIe interface? Performance isn't an issue, even a USB based card would be fine. I know that there are USB based Expresscards that will work, but my expresscard slot is already used full-time. Thanks guys.

Most of the cards that your Google search show interface with the miniPCIe slot in a non-standard way. As I said before, these netbooks bring out the SATA or PATA lines to the miniPCIe connector in a way that normal laptops do not.

When I said that a USB based card would be fine, I meant a miniPCIe card that used the USB lines available on the connector (most cellular cards work this way). I want a card that is always there, internally, not sticking out like a USB flash drive or USB hard drive would be. My goal is for automatic backup that I don't have to remember to use. I don't want to have to plug in a usb device first, but I also don't want a usb device sticking out 100% of the time, ready to snap my port if I get careless.

Yes, Samsung is about to release SSDs capable running on SATA 1 & 2 interface as well as on the USB interface of normals notebooks.... Samsung really deserves a recognition... They are due on Q3 of 2009.
