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.
Although we easily reach listed specifications with 555MB/s read and 532MB/s write, the transfer speeds don’t quite graduate with file size as we might like to see. This doesn’t necessarily mean there is anything wrong with the drive at all, but we tested a few times and still only returned 40MB/s for 4K read speeds.
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. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.
Crystal DiskMark displays solid performance for the AMD Radeon R7 SSD, especially when we look at the low 4K random write performance of 155MB/s.
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.
Looking at the result on the right, we get our first glance at IOPS of 92K read and 77K write. AS well, great access times contribute to a Total Score of 1152 and it is always great to see todays products exceed that 1000 point mark.
An ISO score of 415MB/s is great but we would have like to see the other two results to jump a bit. AS SSD Copy Bench is a true to life program where ISO, program and Game files are moved from one spot on the SSD to another, monitoring the top transfer speed and time it takes to move each file.
