Can I connect an eSATA card or FireWire 800 to my 2008 MacBook?

I have a late 2008 12" MacBook with a FireWire 400 slot (only). I am hooking up an 8TB Raid hard drive to it for digitizing, backup and editing on FCP 6 and would like to have a higher speed available than the laptop's FireWire 400 provides. Is there a way to augment/build out the MacBook to utilize either a FireWire 800 slot or an eSATA EC2 card? I don't think this version of the MacBook (MacBook4,1) has a PCI or PCIe card slot. Although I believe it may have a mini-PCIe card somewhere, as the last page of the Users Guide says (under Europe—EU Declaration of Conformity):

"Hereby, Apple Inc. declares that this 802.11a/b/g/n Mini-PCIe card is in compliance with the R&TTE Directive."

Thanks for any suggestions!
