    I understand that the more you use a USB Flash Drive the more chances it can become to disable itself permanently. I lost one from running programs too often from use.

    Any truth to that? I found a Flash drive program that makes it read-only in order to preserve it;s longetiivty.

    How true is this Thanks

    Yes, apparently they do have a limited number of reads and writes. Seems like I remember reading about numbers quoted in the millions. But no matter the exact number. The issue is that they do not have an unlimited life.

    So far, I have been fortunate and not had any failures. But I do back up my main flash drive to another... :)

    most usb flash drives have 10 year warrentys so the companys must think they last quite along time

    NAND based flash drives are good "for up" to 1 million read/write cycles to any one memory location. This can be countered somewhat by additional chip logic that carries out "wear levelling" i.e. dynamically remapping the blocks in order to spread the write operations equally between sectors.

    Regards
