Can I disable any macOS filesystem cache for USB devices so I can eject them without potential damage to the data?

When I have a USB device like a SD card, USB drive or external hard drive, I always need to unmount it, otherwise OS X complains about the device not being ejected properly. (It’s [possible to disable this message](https://apple.stackexchange.com/questions/6078/disable-the-disk-was-not-ejected-properly-message) , but that’s risky.)
On Windows, the solution to this is trivial: Disable the filesystem cache for USB drives, so that they can be immediately and safely removed.
Does OS X have a way to disable the cache?
