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.
In ATTO the Intel 660p achieved a max of 1.91GB/s read and 1.78GB/s write speeds.
Crystal Disk Benchmark is used to measure read and write performance through a sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.
Crystal Disk Mark reveals similar performance as ATTO. Sequential read hit 1932MB/s and sequential write hit 1794MB/s. 4K performance proves to be very good with a read speed of 55MB/s and a write speed of 130MB/s at QD 1.
The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.
As we normally see, AS SSD’s scores show a little lower than the previous benchmarks. Here the 660p attained an overall score of 2280 points with sequential read and write speeds of 1.76GB/s and 1.64GB/s, respectively. In terms of IOPS, the 660p reached 152K/187K IOPS read/write. And lastly, it delivered copy speeds that exceeded 1GB/s in the ISO and game portions of the test.
ANVIL STORAGE UTILITIES PROFESSIONAL
Anvil’s Storage Utilities (ASU) is the most complete test bed available for the solid-state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. 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 use in our benchmark testing.
Overall, the Intel 660p scored 10,429 points. Read and write speeds are similar to what we have seen thus far. As well, we can see that it was able to reach 108K IOPS read and 226K IOPS write at a QD of 16.
