I would say yes. I assume you're using the term "crash" loosely since an HDD crash is when the heads make contact with the platters. Flash drives (and SSDs) don't have heads or platters (they're solid state) so can't crash, per se, but can still fail.
In my experience, flash drives are much more prone to failure than external HDDs. I believe it's because they are handled with a much more cavalier attitude and tossed into toolboxes, laptop bags, pockets, etc... and constantly inserted and yanked in and out of USB ports.
