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.
Our next look with Crystal Disk Mark shows us that each capacity is able to reach over 560MB/s read and 500MB/s write. 4K speeds on the other hand are a tell tail of a value based product, reaching 29MB/s read and 78MB/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.
AS SSD gives us our first look at IOPS performance with this new SSD series. While read IOPS were fantastic for all capacities, reaching over 90K, and write IOPS were on point with spec for the 480GB and 960GB capacity, the 240GB model’s performance was less than desirable. Overall scores were roughly 900, 1000, and 1100 per each capacity and an increase in 4K speed from CDM is very good to see.
ANVIL STORAGE UTILITIES PROFESSIONAL
Anvil’s Storage Utilities (ASU) are 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.
In our final synthetic benchmark, Anvil Storage Utilities, we can see that the lower capacities don’t do so well in terms of their overall scores. The 960GB capacity is the clear winner having much higher random write performance at higher QD depths. However, when you focus on the read performance, all capacities prove to be roughly the same.
