There are now many data mobility options besides the humble - and hardly 100 per cent reliable - floppy disk. USB technology has proven a particular boon, and Transcend's JetFlash range of stylish drives have the greatest capacity of all such devices. Starting at a sizeable 16MB capacity, the JetFlash range is now capped by a 1GB model that utilises the USB 2.0 interface. The JetFlash 1GB features security features such as a write-protection switch so that data isn't accidentally erased, and has a shock-resistant case. The JetFlash is ideal for all kinds of data storage, from simple document storage to allowing users to take their MP3 collection with them wherever they go. The unit is less than 10 centimetres long and weighs just 24 grams. It is available for a retail price of $950 from Achieva Technology Australia.www.achieva.com.au.
