David; It seems to me, from these discussions, that you may not be actually testing the reliability of the USB's. This is if you are testing a live fs. The unknown in the picture is the size and presence of the overlay and when it will be exhaused. This may, as Doug suggests, be what causes ea

Thanks for taking the time to respond. I started running the tests last week to see if we could generate some data from which we could make some predictions on the reliability of various lots (model, size, firmwre) of USB memory sticks. The original idea was that name brand sticks might last

I am currently at the hypothesis stage. My hypothesis is that something is causing an excessive number of reads/writes to a small portion of a USB memory stick. My first guess is that the problem is the interaction of _cheap_ usb chips/firmware and the filesystem overlay. The test are described

Thanks for joining us Douglas. I would like to point out that there are two separate yet interlinked issues at hand: 1. Easy and fast install. 2. Running OS natively on removable solid state media. Douglas' Liveos solved the first issue. It is very fast and easy to install an OS to a hard drive
