FWIW I bricked a very cheap consumer SSD by using it as write log for my ZFS array. This was my experiment machine, not a production server.<p>Fortunately I had followed accepted practice of mirroring the write cache. (I&#x27;d also used dedicated, separate host controllers for each of these write-cache SSDs, but for this cheap experiment that probably didn&#x27;t help.)<p>So yes this really happens.
