With ATA drives, this is strictly a userspace "policy" decision. Most of us want longer lifespan and 2X the performance from our hardware, and use UPSs to guarantee continuous power & survivability. Others want to live more dangerously on the power supply end, but still be safe on the filesystem end -- no guarantees there, even with "hdparm -W0" to disable the on-drive cache. Pulling power from a writing drive is ALWAYS a bad idea, and can permanently corrupt the track/cylinder that was being written. This will toast a filesystem regardless of how careful or proper the write flushes were done. Write caching on the drive is not as big an issue as good reliable power for this.
