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: Being a SATA II drive, obviously the overall performance numbers of the Crucial V4 are going to be less than that of the SATA III drives we have in our comparison list. On this benchmark, the scores are actually very good for a 3Gbps drive and well above the rated specifications of 230MB/s reads and 190MB/s 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 all of them.
Benchmark Results: Performance in terms of top end numbers drop off here considerably. Many of the top SATA II drives we tested posted overall scores in the 400’s as a matter of comparison.
Benchmark Results: In terms of impact of data compression on performance, it doesn’t play much of a factor as the lines on the graph, outside of the anomalies, are relatively flat across the compressibility scale.
