Samsung SSD 840 EVO mSATA 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 Samsung SSD 840 EVO mSATA drive put up some excellent numbers in the lite-duty SANDRA file system benchmark, besting all of the other drives we've tested.

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 840 EVO mSATA drive also rocked the ATTO disk benchmark. With transfer sizes in the 4K to 64K range, nothing else could touch it.
