Note: Read results are removed because gpcheckperf returned unrealistic measurement. The reason is that gpcheckperf uses DD command to prepare a file that contains zeros for the read test. Due to optimizations for zero data at the storage layer, the reads never reach the SSD drives, and the bandwidth that is returned is unrealistically high, not reflecting the read bandwidth of actual data stored in PowerFlex.
