I think that the cache mode only affects the behavior when you flush buffers or unload the SCSI disk driver. If the mode isn't write-through the driver will send a SYNCHRONIZE CACHE command to force the drive to write its dirty buffers to the medium. Ideally the same thing should happen when you unplug the device, but obviously it's impossible to send the command then. Changing the cache mode shouldn't make any difference if you don't unplug the device during your tests.
