In Walmart Kanata today found 32 GB USB3 flash drives for $7.95. That's a quarter a GB, so I picked up a couple. Seem to be a Walmart house brand (Blackweb). Curious about timing of USB3, I wrote a little script to copy a large file (an iso for my dancebox distro of 972 MB) and then read it. But of course the buffering made the read back REALLY fast. Looking around on web, I've been using sync; echo 3 > /proc/sys/vm/drop_caches to clear buffers, but the command only works as root. Somehow, I'm sure there's a better way to time the HD --> USB and USB --> HD operations properly. Not a critical task, but I thought I'd compare a few devices, and possibly different formattings of those devices. Actually talked about this several OCLUG meetings ago, but didn't get round to it until today.
