Yes you certainly can, in this case the 8gb CF was setup with SFS but you can use Fat formatted CF cards too (assuming you have Fat95 installed, it's included with Poseiden but most people have it anyway)
I think transfer speeds are similar, I did not check the exact speed of PCMCIA but it's certainly more convenient just to plug in pretty much any USB storage device you like
