Enough for the occasional move of a few files, but not enough for installing an operating system or other important stuff. How should I know? Because I've tried both. When trying to create a boot disk for Windows and Linux with this disk, nothing worked. Let me tell you, after building an entire computer, it really irritates me to realize that I was dependent on a cheap generic flash drive to make it work. With a higher quality disk everything worked without problems. Your mileage may vary, but I will never waste my time or money on cheap flash drives again.
