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. In testing the Mushkin Scorpion Deluxe PCIe SSD, we see markedly higher results when testing compressible data samples (left):
Testing in incompressible data seems to have brought the performance down a bit in CDM, however, we just love to see low 4K random write results over that 100MB/s mark. Considering the SSDs that we have previously seen surpass this, all others have been top-tier and have earned great reputations as well.
Looking at our four-way comparison with compressible data testing, the Mushkin Scorpion Deluxe displays excellent results in both high sequential write and low 4k write throughput. The Mushkin Scorpion Deluxe PCIe SSD is shaping up to be a very well-rounded PCIe SSD.
Incompressible data testing is the meat and gravy of true SSD testing and the KingSpec has definitely put the Scorpion Deluxe in its place here, although even in this analysis we again see that low 4k write performance above 100MB/s. Amazing!
We wanted to replicate what we had seen in ATTO and felt that QuickBench was just the program to do that. Just as ATTO does, QuickBench measures transfer speeds of files of different sizes.
Although not used as a basis of comparison, we wanted to include Quickbench results to provide further validation of the strength of this SSD.
