Difference between Seagate goflex and expansion?

[gamekraze]

What is the major difference between them apart from portability? Why is goflex costlier than expansion , shouldn't it be the other way around? Is the failure rate worse than goflex?

goflex drives can have there interface changed.

I have a 500gb portable goflex that came with USB2, Since then I've bought an upgrade to usb3 and Esata without having to replace the drive itself. Also these connectors work with non goflex drives (though Lack the protection that the goflex drive offers.) Which makes it useful for copying files off the random laptop hard drive.
