Crystal Disk Benchmark is used to measure read and write performance through sampling of highly compressible data (oFill/1Fill), or 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.
Once again, the SanDisk Extreme Pro SSD is providing benchmark results that we don’t often see. Not only are the high sequential results very positive, but also, the low 4K random write speed of 148MB/s is definitely something to brag about.
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 brought those high sequential scores down a bit but the low 4K random write performance still remains above 100MB/s. The IOPS high of 88K at 4K 64Thrd read is decent, as is the Total Score of 1112.
As well, the AS SSD Copy bench represents respectable transfer speeds and times, however, we have seen higher from other similar SSDs.
ANVIL STORAGE UTILITIES PROFESSIONAL
Anvil 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.
Anvil Storage Utilities highlights the IOPS, as well as disk access times of the SanDisk Extreme Pro SSD. We did a bit of additional ASU IOPS testing to try to stretch the IOPS closer to listed specifications of 100K/90K, however, we were not able to improve what we see here by much.
The SSD Review uses benchmark software called PCMark Vantage x64 HDD Suite to create testing scenarios that might be used in the typical user experience. There are eight tests in all and the tests performed record the speed of data movement in MB/s to which they are then given a numerical score after all of the tests are complete.
The Extreme Pro achieved a high Total Score of 77555 points with a high transfer speed of 426MB/s. A definite plus with respect to this test was that all eight tests resulted in SATA 3 transfer speed results. This is how the Extreme Pro fares in our Vantage SSD Top 10 Hierarchy:
