CRYSTAL DISK BENCHMARK VER. 3.0 X64
Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. Many new SandForce Driven SSD owners who cant wait to test the performance of their SSD often grab this program and run a quick test, not realizing that they are testing with incompressible data rather than compressible data used in testing by manufacturers. We have provided compressible (oFill) results on the left with incompressible (random data) results on the right.
The high sequential results on the left as well as the 4k random writes are decent. In comparing the testing of highly compressible data on the left to the testing of incompressible data on the right, it becomes apparent that asynchronous NAND flash memory was used as it does not transfer incompressible data nearly as fast. This is observable in sequential and 512k write speeds.
As much as we like other utilities, AS SSD was the first benchmark released specific to SSD performance and is still the bread and butter of testing SSDs. Many enthusiasts prefer this software as it encompasses the worst case scenario in disk transfer speeds by utilizing incompressible data.
AS SSD confirms that of which we had seen above in the Crystal test on the right and provides us with a bit more displaying disk access as high as 0.14ms. The IOPS result on the right is a bit lower than expected and will probably move up a notch in Anvil Storage Utilities testing.
AS SSD Copy Bench simply creates three typical files (ISO, Program and Game) and moves them from one spot on the SSD to another. It then provides us with the total transfer time of each file as well as the top transfer speed while moving it. I had to chuckle when first seeing this as I then realized that I had gotten so used to SATA 3 speeds. As this is typical for a SATA 2 SSD, SATA 3 results are typically between 3-7 seconds tops with as high as triple the transfer speeds. Who knows…maybe we will see a SATA 3 ‘SandForce Driven’ mSATA review in the week ahead!
ANVIL STORAGE UTILITIES PROFESSIONAL
Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility. 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 utilize in our benchmark testing.
Anvil shows us some great disk access speeds as well as the IOPS performance being well above the listed specifications of 30,000 IOPS. WE also see those great transfer speeds once again and the reason for this is that the Anvil Benchmark relies heavily on testing with compressible data.
