General Performance Testing/Measuring

All STB Suite tests which measure performance work on SSD drives. Performance metrics logged include:

Transfer rate in IOPs and MB/s
Command completion time
Inter-command latency times

Tests allow setting the blocks per transfer and queue depth for checking how those parameters affect performance.

Tests range from simple (READ, WRITE, etc) to complex (real-world combinations of access type, random/sequential, WRITE/READ)

SSD Precondition test in DMM

To “precondition a drive” is a fairly complex process, a process whose goal is to determine if the drive is in a stable state. This process involves writing the SSD drive twice, and then taking performance measurements, and then mathematically analyzing these measurements to determine if the drive is in a stable state. The new SSD Preconditioning Test incorporates all of this mathematical analysis, alleviating the user from having to digest all the complex criteria for this preconditioning process.
