It so happened that for many years I have been buying products (flash drives and external hard drives) exclusively from Transcend. And this is not an advertisement, it’s just time-tested. There hasn't been a single crash yet. As I understand it, it’s more convenient to use external HDDs for watching from a TV, rather than flash drives, since the HDD automatically remembers where you finished watching, where you finished watching, but alas, there is no flash drive.
