The Platinum P41 manages to exceed its rated sequential read speeds by a fair margin, but does not quite match its rated write speeds. SK hynix Platinum P41 1TB CrystalDiskMark 1GB SK hynix Platinum P41 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. That is something that we are not doing in this review and it takes more time and effort to do it like we are.SK hynix Platinum P41 1TB Performance Testing
Many sites test storage drives as an empty secondary drive and disable drive indexing on that drive to improve their benchmark numbers. Please keep in mind that these scores are on the SN850 running as the primary OS drive and it is filled to 55% capacity. Very solid scores for an AMD Ryzen 5 3600X system with no optimizations and a standard install of Windows 10. The Random 4K performance at QD1 was 74 MB/s read and 229 MB/s write. CystalDiskMark:īenchmark Results: CrystalDiskMark 7 is pretty much the industry standard to get peak performance numbers and here the WD_Black SN850 2TB PCIe Gen4 x4 SSD topped out at 7,034 MB/s read and 5131 MB/s write at QD8. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) and shows the highest score of five runs. We charted the results of the drive at the 128KB I/O size and found that it had the second highest read speed of any that we have ever tested and the third highest write speed.ĬrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. ATTO Disk Benchmark:īenchmark Results: On ATTO Disk Benchmark found that the WD_Black SN850 2TB PCIe Gen4 SSD topped out at 4.79 GB/s write and 6.56 GB/s read at the standard queue depth of 4. The test was run with the default runs of 0.5KB through 64MB transfer sizes with the total length being 256MB. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. ATTO measures transfers across a specific volume length. ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world.
