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: The only surprising thing here is that the reads exceed the specification of 520MB/s by almost 30MB/s more and writes kicked out an extra 10MB/s more over the 400MB/s specification. Writes are a little behind the SandForce drives who thrive on the highly compressible data found in this benchmark.
This test employs compressible data showing the best case scenario in terms of data throughput for the SandForce drives. Let’s have a look at a few others that use incompressible data to see how that impacts the scores.
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 all of them.
Benchmark Results: The 830 Series fares very well here posting a sequential read score a hair off of the leader and the best sequential write scores we have for comparison. The remaining scores were strong as well!
Benchmark Results: The graph shows that, unlike SandForce drives, the Samsung controllers is indifferent about the compressibility of the data it moves so performance remains consistent throughout.
