ADATA Premier Pro SP920 SSD Family Review
SANDRA and ATTO Disk Benchmark
Next we ran SiSoft SANDRA 2014, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provide the results from our comparison SSDs. The benchmarks were run on unformatted drives and read and write performance metrics are detailed below.
Read performance amongst all of the drives tested here was competitive across the board. Writes favored the higher capacity drives (once again), with the ADATA drives trailing only the Vertex 460.
ATTO is another "quick and dirty" type of disk benchmark that measures transfer speeds across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5kb through 8192kb transfer sizes and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than I/O response time, access latency, etc.
The ADATA Premiere Pro SP920 series of drives remained competitive in the ATTO benchmarks too. Of course, the lower capacity drives didn't offer writes that were as fast as the higher capacity drives, but again, that is to be expected since the drives aren't leveraging all of the capabilities of the controller.
