A-Data introduces their Nobility Series USB drive with a unique swivel cover where losing that USB cap is the last not a worry.
The A-Data PD 19 features a metal clip backing for a lanyard or key chain (although not recommended). The USB Nobility Series is available in 2 and 4GB capacities.
The rotating cap only rotates one direct at a full 180 degrees and despite the fact Readyboost doesn’t do much, the PD 19is enhanced for that application.
