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: Very much the results we expect to see with the SF-2281 controller paired with synchronous NAND. The Chronos MX is just a hair off the leaders with the difference not being statistically significant enough to even call it a difference. Very good start.
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 AS-SSD benchmark is where we typically see the SandForce controllers drop back on performance, particularly on the writes, because the data employed by the test is incompressible, precluding the controller from boosting things with compression. Sequential write scores are a bit lower than some of the fastest drives we’ve tested.
Benchmark Results: As usual, the graph shows the mostly linear relationship between data compressibility and performance on the SandForce controllers.
