ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.
Performance of 252MB/s read and 162MB/s write doesn’t quite reach SATA 3 levels but it does improve upon the result that we saw at ceBIT. We would be willing to bet that testing of the 128 or 256GB capacities would result in SATA 3 performance. No matter how you look at it though, these are amazing speeds for a flash drive.
Crystal Disk Benchmark is used to measure read and write performance through sampling of highly compressible data (oFill/1Fill), or random data which is, for the most part, incompressible.
The one thing we watched for with the Crystal DiskMark test was the low 4k random write performance which has traditionally been very low for JMicron hardware. A high transfer speed of 52MB/s was excellent to see.
You may not see this for long (and its definitely not common) but you get a freebee simply for reading! Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and utilize in our benchmark testing.
