That behaviour is defined by a mount option.

What's the proper way to mount flash devices?

Try the sync option. From the man page:

> All I/O to the filesystem should be done synchronously. In the case of media with a limited number of write cycles (e.g. some flash drives), sync may cause life-cycle shortening.
