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 PNY CS2211 was able to achieve maximum sequential performance of 564MB/s read and 458MB/s write for the 240GB model and 562MB/s read and 544MB/s write for the 480GB. On the 4K section we can see a high of nearly 31MB/s for read and almost 82MB/s for write, which is a bit slower than we were hoping for.
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.
During our AS SSD benchmarks we can see that the 480GB model has a very slight lead over the 240GB model due to its faster sequential write speed. Overall, the 240GB model reached 1181 points while the 480GB model reached 1202 points! These results are very good! Both drives reach 527MB/s read and 240GB mode reaches 436MB/s write while the 480GB mode reaches just over 500MB/s. 4K QD1 performance is about 35-37MB/s read and 71MB/s write. Access times (latency results) are also very good. During the Copy benchmark, both drives delivered impressive results 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.
Finally, in Anvil we see that the performance is in line with what we have seen in the other tests. Overall, the CS2211s reached total scores in the nearly 4,900 point range which, again, is very good. Let’s continue on and see how these drives handle our more realistic PCMark test suites.
