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.
As ATTO seems to display, Intel results are lower than the AMD right off the hop. Both samples display something we like to see which is a steady speed increase with data file size increase.
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.

Looking specifically at the 4k Read result in the top left benchmark result of both the AMD and Intel Test Benches, we see first hand what Phison had mentioned with respect to low QD read performance. 99MB/s (AMD) and 102MB/s (Intel) low 4K random read performance are two of the best results we have ever received, short of the Intel Optane Testing some time back. This performance specifically is where one might recognize faster visible PC activities.
Aside from that, there are so many takeaways from a comparison of these results, the most obvious being that AMD provides higher sequential performance results consistently, whereas, we find better IOPS with the Intel Bench.
