5.3.6 IO METER

IO Meter tests the RAIDDrive’s transaction speed in I/O operations per second. We ran this test

with queue depth settings of 1 ~ 64. The larger queue depth tended to offer the highest

transaction speeds. We specially ran this program for 50 minutes per each thread at the Steady

State SSD status.
