[lopsa-tech] USB Flash Drive Reliability

2015-11-17 Thread Edward Ned Harvey (lopser)
In regular hard drives and SSD's, they have FEC chips or equivalent (forward error correction) so whenever the platters return a bit error, that error should be noticed and the corrupt data should not reach the OS. I have seen many times, USB and SD cards start silently returning corrupt data.

Hi Ed, There's some good information here: https://www.blackhat.com/docs/us-14/materials/us-14-Oh-Reverse-Engineering-Flash-Memory-For-Fun-And-Benefit-WP.pdf Basically though, USB drives are cheap, and they're frequently disconnected from power for extended periods of time, plus the flash control
