This way you can setup > stuff.. I have found an Install on a USB stick really really slow. Better to run from the live ISO on a USB stick. Writes to a USB stick are about 1/8 the speed of reads. I have used a USB drive (real hard drive) and been very happy with it, but when I got a USB stick to install to... well try it. A 32G USB stick is $15 at Walmart these days. Mounting noatime may help some, but I was so disappointed I didn't try. The install itself was arduous already. I then did some research and there are faster USB sticks, but not that much faster, maybe double write speed. Running from a live USB of course takes up some of your memory as a ram drive (much better performance) so there is less system ram left for software to use. In a class situation... one needs to know how much memory they have to begin with. Depending which live ISO you use it may be possible to mount the windows drive for temporary use. The least intrusive method being to drop a large file one there that can be mounted as a linux partition (ext* file system). This can be backed up to the USB stick at the end of the day. Anyway, I would not agree to lead a class in this way until I had made a USB stick up and tried it on their machines to make sure I was able to cover the class material I intended to cover. -- Len Ovens www.OvenWerks.net _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
