128K Sequential Read/Write
The 128K sequential speeds reflect the maximum sequential throughput of the SSD using a realistic file size actually encountered in an enterprise scenario.
Both the CloudSpeed 500 and the SM843 are closely matched in this test, with an average hovering around 530MB/s.
The CloudSpeed falls in sequential write speed to the SM846, with an average of 425MB/s. The SM846 averages an impressive 487MB/s in sequential write speed at QD256.
The CloudSpeed 500 again manages good marks as we mix in a read workload in steady state conditions.
Both SSDs give great latency performance at 128K sequential write, with the SM843 actually providing 100% of its I/O's in the 60ms range. The CloudSpeed 500 provides 982,528 I/O's (93.72%) at 60-80ms, and 65,846 I/O's (6.28%) at 80-1900ms.
The CloudSpeed 500 averages 3.83 Watts, and the SM843 averages 3.65 Watts.
The CloudSpeed 500 gives 113MB/s per Watt, and the SM843 provides 129MB/s per Watt.
