Can the SDFileSystem.bas module work with SPI memory

I have a need to write a small file to a fat16/32 file but need to collect and write data quickly. Ramtron has a 2 meg SPI memory that is plenty big and fast enough. Would the SDFileSystem work with this device since it uses SPI? Figured it would be much easier and quicker to post the question vs. trying it first.

Thanks for any help.

FYI: I'm not affiliated with with either of these companies, just sometimes need fast memory. Also a link to the lowest price I could find.

I doubt that it would work without some changes. How fast do you need to write to the memory?

Am reading an accelerometer xyz (word each) data at 80 hz and writing to memory. The Ramtrom memory is more expensive but easily keeps up with that. Want to be able to read/write faster if possible. I could write to the Ramtrom memory then re-write to an sd card to make the fat 16/32 file to send off but would be nice to skip that hardware and step.

Thanks for the reply. You have been invaluable help in the past.
