ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5KB through 8192KB transfer sizes with the total length being 256MB.
Benchmark Results: Obviously, the 840 Series drive is not going to win any major awards for write speeds with performance being capped around 265MB/s but reads are excellent, hitting the fastest speed in our comparison for the 4MB test.
We have been running the AS-SSD Benchmark app for over some time now and found that it gives a broad result set. The programmer has worked very hard on this software and continues to make updates often so if you use it, show him some love and send him a donation. There are now three tests that are found within the tool and we’ll show the results from two of them.
Benchmark Results: The incompressible nature of the data used in this benchmark had little effect on the outcome of the performance as scores are very much near where we saw on the ATTO benchmark which usually indicates a best case scenario performance outcome. Consistency is good!
Benchmark Results: Holding true to the statement made above, the level of compression has no discernible effect on the performance as the graph has virtually no slope for either line..
