The Imation Micro Drive uses a USB 2.0 connection to a PC and will be compatible with all three major operating systems: Windows, Mac OS and Linux. Imation says its target audience for the new drive is industry professionals who require the transport of large files in their lines of work, such as advertising or science.
Initially available in a 2-gigabyte capacity, the company plans to have a 4GB version available late this year
