The SSD Review The Worlds Dedicated SSD Education and Review Resource | 
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.
Off the bat, SMI’s SM2262EN displays some impressive performance. In ATTO it achieved 3.3GB/s read and 2.9GB/s write.
CRYSTAL DISK BENCHMARK VER. 6.0.0 X64
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.
Silicon Motion’s SM2262EN delivers sequential speeds of over 3.4/2.9GB/s read/write at QD32 and 1.85/1.75GB/s at QD1. As well, we can see that it hit 1.38/1.32GB/s worth of random throughput at QD 64, which is about 350K IOPS. In terms of 4K QD1 performance, the SMI SM2262EN shines. It achieved nearly 61MB/s read and 141MB/s write.
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.
In AS SSD it hit 2.9GB/2.5GB/s read/write in the sequential test, 360/234K IOPS read/write in the random test, and similar 4K QD1 performance to what we saw before in CDM.
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.
Anvil’s results almost mirror that of AS SSD and overall, it scored 14,481 points.
