Just about all current SATA SSDs advertise having some form(s) of "background garbage collection". That "feature" has always concerned me, because of the real possibility of power being removed (system shutdown) while the drive firmware is in the midst of re-shuffling my data around. One would hope that "STANDBY IMMEDIATE" is taken by the drive as a signal to stop that fussing about and prepare for full/sudden power-off. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
