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.

Synthetic HDD Benchmarking

 

The Samsung SSD 850 PRO drives led the pack once again in the SiSoft SANDRA read test. The 1TB also led in the write test, but the 128GB trailed somewhat.
 
ATTO Disk Benchmark

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 Samsung SSD 850 PRO drives' performance in the ATTO benchmark is nothing short of impressive. Both drives clearly outpaced every other SSD we tested with small file transfers.  And once they hit the 16K mark, they don't quite blow away the competition, but they perform extremely well nonetheless.

And with RAPID mode enabled, you can see just how much faster data transfers can be when leveraging system memory. Reads topped out at over 3GB/s, while writes peaked at about 844MB/s.
