This comparison will show the performance of the previous driver, followed by the new.
The results can be expanded to full view by clicking on the graphic. We can see that the updated driver is exhibiting some very strong performance, with over 3GB/s! These are truly phenomenal results, and the highest that we have reached with any single storage controller that is not using cache to boost the speeds. The write results are very similar to the previous version, with some higher performance in a few areas.
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. We have provided compressible (oFill) results for CDM, choosing to leave random data results for AS SSD on the following page. The M4/C400 performs the same regardless of the compressibility of data, so the random results would be repetitive.
We can see here that the sequential file speeds are higher, but not twice as fast. Some would mistakenly think that HighPoint is referring to sequential speeds when they are referring to the 50% increase. These results successfully demonstrate true extent of the increase with the 4K random score for write speed having doubled from 55MB/s to 111 MB/s, as well as an appreciable increase in the ‘base’ 4K read speed. The improvement is also nothing short of phenomenal when comparing the 4k-QD32 results as the write speed has doubled to 434MB/s as well as that of the read speed which has also doubled, and then some.
The random scaling is excellent, with high Queue Depth read results of 506MB/s that are rarely seen outside of very expensive RAID controllers. Random speeds are the key measurement that results in perceivable performance improvements in operating system environments. With results such as these, this device would be very well suited for operating system usage.
