Kingston DC500 SSD Review: High Capacity Enterprise Storage
Kingston DXC500R/M - SANDRA, ATTO Bandwidth & IOs
Next we used SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant for some quick tests. Here, we used the Physical Disk test suite and provide the results from our comparison SSDs. The benchmarks were run on clean drives that lacked any partitions. Read and write performance metrics are detailed below.
ATTO is straightforward 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 64MB 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.
Once again, all of the SATA-based drives were tightly grouped, regardless of the transfer size being used. The Kingston drives had slightly better performance at the smallest transfer sizes, but things leveled off quickly.
Peak write IOs with the smaller transfer sizes were also somewhat better on the Kingston drives versus Samsung's competitive offerings. The tables turned in the read test, however.
