PQI released the world’s first retractable USB port on a USB flash drive. By doing this, PQI completely eliminates the need for a cap to cover the USB connector, just simply slide the connector back into the chassis of the flash drive. Like other PQI Cool Drive series, the Cool Drive U350 comes with USB Notebook Professional security and personal management software. In September, USB Notebook software’s email functions were upgraded with Microsoft Outlook synchronization capabilities which makes carrying your personal emails that much easier. PQI offers the drive from 512MB capacity to 4GB capacity.
