We, as a family, each have a pc/laptop on which we were storing an ever increasing amount of music, photos, school work, study material etc. To ensure the safety of this data we decided to purchase an external hard drive.
The reason we chose this portable version was simply because it was portable and meant that anyone one of us could take it to work/school and access the data or add data without the need for various memory sticks. The FreeAgent GoFlex - Hard drive - 500 GB - external - Hi-Speed USB stood out as value for money as well as having a good storage capacity, the fact that it is a Dell product also helped us to make our choice. It is only 8x11 cm and when carried in the handy (hard backed) protective pouch that came with it, it fits easily in a bag or pocket.
A versitile product that has improved the security of our personal information no end.
