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.
Next up in Crystal Disk Mark we can see the CS2111 XLR8 was able to achieve maximum sequential performance of 525MB/s read and 443MB/s write. On the 4K section we can see a high of 32MB/s for read and 140MB/s for 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.
In AS SSD, the XLR8 CS2111 reached a score of 981, a similar score to other drives utilizing this controller. Sequential speeds hit 514MB/s for reads and 43oMB/s write while 4K speeds reach 30MB/s for read and 121MB/s for write. Furthermore, the drive reached 70,458 read IOPS and 69,643 write IOPS. Access times are for read and write are both around 0.030ms.
To complement this, the AS SSD Copy Bench presents us with transfer speeds for different file types. The CS2111 XLR8 reached a high of 421MB/s for the ISO test. For its lowest value, it reached 259MB/s on the game test.
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 Anvil Storage Utilities, the max sequential read reaches 491MB/s and sequential write comes in at 425MB/s. 4K speeds prove similar to the other benchmarks, 31MB/s for read and 129MB/s for write. Testing with compressible and incompressible data has presented no issue for this drive so far and there has been consistent performance across all tests.
Now to achieve the maximum IOPS, we used Anvil’s threaded read and write tests with 4KB data. For read we were able to reach 71,342 IOPS and for write we hit just under the rated value at 73,468 IOPS.
