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.
As listed performance for the Optane 800P is 1400MB/s read and 600MB/s write, this initial benchmark appears to be bang on. Personally, my favorite use of this particular benchmark is seeing that it is a very stable SSD in the gradual and steady performance increase as sample data sizes are increased.
CRYSTAL DISK BENCHMARK VER. 5.5.0 X64
Crystal Disk Benchmark is used to measure read and write performance through 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.
This is perhaps one of the best Crystal Disk Mark results we have ever seen. Typically, we might see the performance of an SSD drop for this benchmark, as we are now testing with incompressible, vice compressible data samples…but not with the Intel Optane 800P. Not only is the sequential performance bang on, but also, low 4K reads are nice and high as we typically see in Optane SSDs; this is where a visible performance increase comes from. The low 4K write result of 232MB/s isn’t anything to complain about as well.
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.
Once again, we see what we might expect from high sequential, as well as random performance. In addition, we can confirm that listed IOPS specs are also bang on at 345K read and 141K write.
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 Storage utility benchmark is another software program that traditionally knocks SSD performance down a few notches. This test, once again confirms that the Intel Optane 800P is a solid SSD.
