Kingston HyperX Predator M.2 PCIe SSD 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.
The HyperX Predator PCIe SSD nearly hits is rated specifications (1.4GB/s read, 1GB/s writes) in the SANDRA physical disk benchmark, besting the other drives we tested by a wide margin.
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 HyperX Predator PCIe SSD showed some measurable performance drops with 128K - 512K transfer sizes in the ATTO Disk Benchmark's write tests, but it still led the pack by a wide margin. Reads were strong as well, though the HyperX Predator PCIe SSD didn't pull ahead of the other drives until transfer sizes exceeded 8K.
