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.
Crystal Disk Mark also shows us some impressive 4K write speeds, both SSDs reaching over 150MB/s. 4K reads average 34MB/s. Both SSDs were also able to each over 500MB/s read and 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.
The 500GB and 1TB MX200 reach a total score of 1089 and 1077 respectively. Read speeds both reach over 500MB/s and write speeds of 480MB/s. Both were unable to achieve rated IOPS in this test. Both SSDs reach 32MB/s for 4K read and over 130MB/s for 4K write.
In the Copy test both SSDs have very similar performance, both reach their fastest performance with the ISO file and lowest with the Game file.
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.
With a result of 5,427.54 points the 1TB beats out the 500GB overall which achieved 5,367.24 in this test. Looking at 4K performance again, we see that both capacities were able to hit 32MB/s read and over 140MB/s write. In this test we were able to achieve the rated write IOPS, however, read IOPS are still low. Let’s move on to our next test and see if we can hit that 100K mark!
Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation however, they discontinued work on the program. In 2003 it was re-launched by an international group of individuals who are now continuously improving, porting and extend the product that is now widely used within the industry.
Because we were unable to achieve the rated read IOPS with our other benchmark programs, we decided to give it a go with Iometer. Luckily for Crucial, we were able to achieve a bit over 99K IOPS. Being just a few hundred IOPS off is well within a 1% margin of error.
