I have been thinking about storage lackage of my old USB disk of 256MB, which has been used for 4 or 5 years with USB 1.0 interface. It's small, because I need large storage to move data from the work pc to my notebook or transfer large-size files. However, the mobile hard disk is not very convenient to mount in old Linux system. So, I choose a large-storage USB disk, SanDisk Cruzer Counter 8G, subscribed on amazon.cn with RMB236.80, 50% off and which is cheap enough I believe.
