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.
Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. Many new SandForce Driven SSD owners who cant wait to test the performance of their SSD often grab this program and run a quick test, not realizing that they are testing with incompressible data rather than compressible data used in testing by manufacturers. We have provided compressible (oFill) results on the left with incompressible (random data) results on the right.
Crystal DiskMark results are typically lower than ATTO Disk Benchmark scores. Of worthy mention with respect to both of these tests are the fantastic 4k random write transfer speed results of 96MB/s which is, for the most part, uncommon in most SSDs. Those who have followed our previous reviews know that these low 4k scores play a very important part of the visual upgrade from a hard drive.
ANVIL STORAGE UTILITIES PROFESSIONAL
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. Lets see how the Patriot Pyro SE SSD does in Anvil testing.
Anvil Storage Utilities have become one of our favorite bench mark programs because it represents the most complete benchmark results and information shown in any software that we have seen. For example, our system information is listed on the lower left while complete SSD information is listed on the lower right. Anvil is also the only program that tests IOPS and transfer speeds simultaneously.
Specific results that stand out in this benchmark are the incredible access times and, once again, the low 4k random results of 84MB/s. Specifications list IOPS at 85,000 while our results are just a bit lower.
