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: As we suspected in the article introduction, the specifications for the Strontium Hawk were a bit conservative with max ratings at 510MB/s reads and 470MB/s writes. Here we see each of those eclipsed by a fair margin, hitting reads of 557MB/s and writes at 530MB/s at peak.
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: Of course, the ATTO benchmark shows a best case scenario where the AS-SSD benchmark negates the majority of the performance gains via compression and scores reflect that plainly.
Benchmark Results: Typically on SandForce drives, we see the writes ramp up as data compressibility increases but in this case, it appears the reads follow suit although with slightly less pitch.
