hdparm is a command-line tool on Linux for querying and setting the hardware parameters of SATA/IDE disks. -I shows device information, -t and -T give quick measurements of sequential read and cached read speeds, and it can change settings such as the standby timer, write cache, and acoustic management. Some options can corrupt data, so care is needed.
