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.
In Crystal Disk Mark the XPG SX930 was able to achieve slightly better peak sequential performance as well as 4K performance in the 120GB capacity. The larger capacity results are respectable, however, with both reaching over 540MB/s read and their rated write speeds.
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 clear look at IOPS performance. The 120GB and 240GB models showed around 50-55K IOPS while the 480GB model reached ~70K in read and write. Overall scores were 849, 910, and 986 per each capacity We can see that the 4K speed read continues to be a bit better in the smaller capacity as well.
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.
240GB 480GBLooking at the overall scores for Anvil, performance is getting closer and closer to one another. The 120GB’s write performance is starting to fall off, reaching just 381MB/s while the 240GB and 480GB models maintain a slight advantage. Besides that, most aspects are in line with what the other benchmarks have shown thus far.
