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.
Benchmark Results: On ATTO Disk Benchmark we see that the ADATA Ultimate SU500 1TB SSD reached speeds of up to 495.88 MB/s read and 458.18 MB/s write at a Queue Depth of 4. This drive is rated at reached speeds of up to 540 MB/s read and 520 MB/s write. We were never able to reach those scores on our AMD Ryzen X570 powered test platform.
CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds.
Benchmark Results: The ADATA SU750 1TB drive maxed out at 511.29 MB/s read and 482.94 MB/s write in the standard sequential write test that is done at Q8T1. Random 4K performance topped out at 59,900 IOPS read and 46,400 IOPS write.
