If you want a cheap alternative to USB harddrive you could stick them on DVD disks as each disk is 4.7 GB and fairly inexpensive as you'd only need 9 disks. I used to use DVD disks at school for saving data as they blocked the USB ports because people keep doing things they shouldn't to the system :p you just write the data to disk as you would a blank CD then when you want the data off it you just right click on the disk icon and select open disk and copy the files
