LaCie is back with yet another external hard drive, this time it will be known as the LaCie rikki, where it is touted to be the most compact 2.5″ hard drive available at the moment. Coming in brushed, sturdy aluminium, the rikiki is able to hold up to 640GB of data within despite measuring a diminutive 109.7mm x 75mm x 13.4mm. Playing nice with both PC and Mac platforms, the rikki features integrated backup software and plug-and-play capability. Should 640GB be out of your financial reach, you can always settle for 250GB and 500GB capacities, with prices starting £69 upwards.
