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 Corsair Force 40GB destroys the Intel 40GB drive on this benchmark – especially in the writes department. Although not represented in the grid, this was the case up and down the file sizes for this benchmark. The numbers also align with the larger SandForce based drives we have tested.
We have been running the AS-SSD Benchmark app for over a year now and found that it gives a broad result set. Many testers are using the 4k file size read/write results for the IO Meter benchmark which is an old tool and the AS-SSD benchmark essentially shows the same metric in its results set. The programmer worked very hard on this software and continues to make updates often so if you use it, show him some love.
Benchmark Results: The Intel 40GB fares much better here besting the Force 40GB in sequential reads but the remaining scores are relatively close. Neither approaches the scores of the larger capacity drives in sequential read/writes.
