Phison E18 B47R Fortis NVMe Gen 4 SSD Evaluation Sample Preview – The Great Intel/AMD Test Bench Comparison


Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.




There is so much data available in this this Intel/AMD comparison, and just as much consistency, especially when we start looking at low 4K random read and write data throughput once again. The Intel result of 91MB/s low 4K read and 373MB/s write is just amazing.


  1. Any hints on what endurance rating we can expect? (TBW for 2TB model)

    • Can’t speak for the TBW – that is, warrantied writes – but the endurance on this flash should be quite good. Possibly in the 5K P/E range.

      • Thanks for jumping in NewMaxx…welcome anytime.

        Les, would really like to see you guys adding a detailed thermal performance test for nvme drives. Thanks and keep up the good work.

  2. Pls pls pls, run one of these benchmarks with such modern PCIe 4 drive on “old” PCIe 3.

    PCIe 3 should not tamper with those 4K random low QD speeds (but only with the sequential high QD ones) and, if that’s the case, maybe it’s time to consider such PCIe 4 drive for my PCIe 3 laptop. Really, this kind of modern drive is 2.5x faster than good PCIe 3 ones where it matters most.

  3. I’m sorry but why is a site that is solely focused around testing SSDs not including ANY figures or testing regarding power management?

    Anandtech does, and their site isn’t focused solely on SSDs
