Prior to e.Digital, you would have had to page data out of SSD and back into SSD as well.

rephrase:

Prior to e.Digital, you would have had to page data out of SSD into RAM and back into SSD under similar status quo circumstance, e.g ....Ban/Msystems/SNDK. You would also manage a directive data structure paged out of SSD into RAM as well, and back into SSD….be it a UNIX type, or other…e.g.. DOS type…etc…

Just so there is no confusion of anyone looking over our shoulder.

There is e.Digitals patented paging methods(caching) for managing data...and then there are all the others.
