BenchMe is a free tool to evaluate performance of various data storage devices. BenchMe measures access time, linear read speed, and IOPS for queue depth 1 and 32. BenchMe allows to copy benchmark charts to a clipboard or just print them out.
Cropel is a tool to monitor storage devices. Based on the SMART data, Cropel warns about imminent failure, predicts a device failure, displays a history and frequency of SMART values. When trial expires Cropel works as usual but stops predicting.
Lowvel is a free tool to erase data from storage devices irreversibly. The tool overwrites data stored on the device with zeroes. Lowvel is also used to force a device to reallocate bad sectors, or improve write performance of an SSD without TRIM.
