Yes its quite possible (as long as the apps in quesiton allow you to chose where they get installed). Be sure to chose a USB drive that is fast, they do vary (look at the read and write specs in MB/sec)Quote from bronks:
I'm quite ignorant on this subject having never used one. My question is:
Would it be possible to run all my trading apps off of a USB device? I'll be moving into a shared office space environment and even though I will have my own "office" complete with locking door, I still have some reservations about leaving my PC unattended. If I could just take my programs with me, security probably wouldn't be an issue even if my PC get's ripped off or broken into.
Is this possible?
Now, Microsoft wants to give USB an even application-critical task. The company's idea, called SuperFetch, is to accelerate startup times of most used local applications & files by pre-loading them onto a USB stick.
This is technically a way of outsourcing virtual memory to fast NAND memory via USB bus. By enabling the SuperFetch, application will reportedly load 80% faster. This is definitely a novel idea since USB has super fast access time and by the time Vista ships, flash drives are well on their way to hit 50MB/s, plenty fast for caching any files.
