ATTO & AS-SSD Benchmarks
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.
ATTO – Intel P67 Platform
Benchmark Results: As we’d expect, the SX900 kicks out some great scores although none are quite high enough to take the top spot. They are pretty much spot on the specifications given by ADATA. This is the typical performance for the SF-2281 controller on a benchmark using compressible data allowing the controller to maximize its potential.
AS-SSD (1.6.4237.30508) Benchmark – Intel P67 Platform
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: Equally as expected, the AS-SSD benchmark uses incompressible data which really impacts the write scores SandForce controllers – by nearly a third in this case which is a little worse than some similarly equipped drives. Again, the results match what ADATA lists in their specifications for this drive size.
Benchmark Results: Because the controller uses compression to boost performance, there’s a direct relationship between write speeds and the level of compressibility of the data in process. The graph illustrates this nicely with performance being best at 100% compressibility.
