This benchmark was run with both a 1GB and 8GB test size. Anvil’s Storage UtilitiesĪnvil’s Storage Utilities is a comprehensive benchmark that gives us a very in-depth look at the performance of drives tested. The biggest takeaway here is the inconsistency, rather than the actual results. Performance inconsistency remains on the larger ATTO test. KLEVV C920 1TB ATTO 8GB KLEVV C920 1TB ATTO 8GB Chart Write performance, on the other hand, is significantly inconsistent and off the mark in terms of overall performance. Read performance remains very strong and is essentially tied for the top result, but it exhibits inconsistency over the run of the test. KLEVV C920 1TB ATTO 256MB KLEVV C920 1TB ATTO 256MB ChartĪTTO test results tell a vastly different story than CrystalDiskMark. ATTO was tested at both 256MB and 8GB file sizes. The ATTO Disk Benchmark has been a staple of drive sequential performance testing for years. There is only a tiny performance drop observed when using the larger CrystalDiskMark test, which is nothing to worry about. KLEVV C920 1TB CrystalDiskMark 8GB KLEVV C920 1TB CrystalDiskMark 8GB Chart Overall this is a good result for the C920. Read performance slightly exceeds the rated 7000 MB/s, while read performance narrowly misses the rated 5500 MB/s. In CrystalDiskMark the KLEVV CRAS C920 lands essentially on-target for performance. KLEVV C920 1TB CrystalDiskMark 1GB KLEVV C920 1TB CrystalDiskMark 1GB Chart CrystalDiskMark 圆4ĬrystalDiskMark is used as a basic starting point for benchmarks as it is something commonly run by end-users as a sanity check. We test using both the default smaller test size as well as larger test sets on our benchmarks. This allows us to see the difference between lighter and heavier workloads.
