Optima Pro™ Attaché® USB 2.0 Flash Drive was designed with Windows Vista™ in mind, and works in conjunction with new SuperFetch (intelligent caching) to enhance system performance for quicker startup and windows multi-tasking. You can get a boost in system responsiveness without upgrading internal components (such as processors or RAM). You can define the amount of storage you want to allocate toward ReadyBoost™, and how much you want to use for traditional storage, so Optima Pro Attaché still makes a great solution to capture, store, and share digital images, music, games and documents.
