Mapower MAP-H31SS 3.5" eSATA External Enclosure
 

Calling this external enclosure 'portable' might be a bit of a stretch right now. I am pretty sure that one would not be able to take this unit to work and just plug it into any PC they find. However, if what you need is the fastest external solution available then the Mapower MAP-H31SS is the way to go, offering full hard drive speeds with a semi-portable enclosure.
