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: Though the controllers are all identical (SF-2281) performance varies on the smaller drives as they carry only one NAND die per package which has an obvious performance impact, at least on the writes.
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 results show an incremental improvement in performance as the drive capacity increases on the sequential tests and the overall scores reflect just that.
Benchmark Results: Typically with SandForce drives we see the write performance ramp up as the data becomes more compressible and that holds true here with the read performance remaining relatively linear and flat.
