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 DiskMark pretty much displays what we have already seen with high sequential data transfer, but also adds decent random read and write speeds as well.
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 provides us with performance a bit lower than we might expect, but all still falls within listed specs, given exception to the IOPS which are a bit lower. Considering what we have seen in the SMI SM2246EN controller previously, we would believe the firmware in this case is fitted precisely to IVI System needs. This is similar with Copy Bench results below, these also being just a bit lower than we might normally see:
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.
Anvil Storage Utilities confirm much of what we have seen thus far, providing a bit better of a look at disk access for different test sizes.
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 simulations are as follows:
- Windows Defender In Use
- Streaming Data from storage in games such as Alan Wake which allows for massive worlds and riveting non-stop action
- Importing digital photos into Windows Photo Gallery
- Starting the Vista Operating System
- Home Video editing with Movie Maker which can be very time consuming
- Media Center which can handle video recording, time shifting and streaming from Windows media center to an extender such as Xbox
- Cataloging a music library
- Starting applications
PCMARK VANTAGE RESULTS
The PCMark Total Score of the Super Talent DuraDrive AT7 SSD is 78941 and right up there with the latest upper tier SSDs we have looked at. Looking a bit more closely at the 8 test results, we can see that all 8 scores are what we would realistically see in SATA 3 vice SATA 2, the highest being 450MB/s when testing in media center. We would like to have seen higher scores in the final two tests.
