ATTO & CrystalDiskMark

ATTO v4.01.0f1

ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5KB through 64MB transfer sizes with the total length being 256MB.

ATTO Disk Benchmark:

Benchmark Results: On ATTO Disk Benchmark found that the  Phison E18 development SSD topped out at 6.17 GB/s write and 6.95GB/s read at the standard queue depth of 4. Amazing speeds and we are finally seeing the true potential of PCIe Gen 4 drives! 

CrystalDiskMark 7.0.0 x64

CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. 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.

CystalDiskMark:

Peak Performance Preset

Real Performance Preset

Benchmark Results: The Phison E18 reference drive came in with scores of 6,978.08 MB/s read and 6,841.35 MB/s write on CrystalDiskMark 7! The Random 4K performance at QD1 was 70 MB/s read and 244 MB/s write. Very solid scores for an AMD Ryzen 5 3600X system with no optimizations and a standard install of Windows 10.

Let’s look at some other benchmarks!
