The OCZ Trifecta combines SD, MicroSD, and USB into one super device that may not be a creation of Earth. I's kinda like if one were to combine bacon grease, butter and lard in one package; it's pretty sure to get the job done, whatever it may be.
At its heart, you are really getting a MicroSD card with SD and USB adapters. But since technically it's also a SD card reader (in addition to a USB storage device) it's more accurately a quadfecta. So that would be like a hot dog, Italian sausage, bratwurst and kielbasa all rolled into one.
No word on pricing yet, but it smells fantastic.
