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.
