The Create SSD Test wizard opens.
You cannot select disks from multiple expansion units.
Selecting a single SSD determines the optimum amount of over-provisioning for all SSDs of the same model and capacity. Selecting multiple SSDs determines the optimum amount of over-provisioning for that specific combination of disks and RAID type. Testing multiple disks gives more accurate results, but takes significantly longer than testing a single disk.
All data on the selected disks will be deleted.

Description |
---|---|
Test data size |
SSD Profiling Tool writes the specified amount of test data to the SSD during each test phase. Decreasing the test data size decreases test time but gives less accurate results. |
Over-provisioning test range |
Specify the minimum and maximum amount of over-provisioning to test. |
Test interval |
Specify the over-provisioning increments to test. |
End a test phase early if consistent performance is too low |
SSD Profiling Tool will end a test phase after 5 minutes of testing if the random write speeds during the phase are lower than a system-defined threshold. Tip:
Enabling this avoids wasting time testing disks when the specified amount of over-provisioning is producing no measurable benefits. |
For multiple SSDs, the test may take more than 24 hours.
If the estimated test time is too long, reduce the test range, test interval or the test data size.
A confirmation message appears.
SSD Profiling Tool creates and starts running the test. The test appears as a background task in QTS.
