Since I don’t have 7400euros ($10,420) to spare, I can just hope and pray that someone gifts me this exquisitely designed SolidAlliance Mnemosyne USB key. This expensive USB key is designed by Toshi Satoji Design based in Milan Italy. Named aptly after the Greek goddess of memory – Mnemosyne, this USB key is beauty personified. At first glance you will never believe that this aluminum cube hides a USB key inside it. Designed like a beautiful puzzle it boasts of a 16GB key in its center. Simply stunning, this designer USB key is not just a design masterpiece but a status symbol.
