"The DataTraveler 300 will enable users to carry huge volumes of data with them everywhere they go - up to 365 CDs for example. That's one album for every day of the year, and it demonstrates how far flash technology has developed," said Kirsty Miller, consumer product marketing manager at Kingston Technology Europe.
"Business users and consumers can also safeguard their data by initialising the Password Traveler software which will allow them to password-protect their data in a privacy zone without the need of administrator rights," she added.
