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: ATTO showed the XPG SX6000 PRO 512GB M.2 PCIe NVMe drive reaching speeds of up to 1,980 MB/s read and 1,400 MB/s write in the standard overlapped I/O benchmark.
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.
Benchmark Results: The XPG SX6000 PRO 512GB drive topped out at 2,117 MB/s read and 1,530 MB/s write in the standard sequential write test that is done at QD32. Sequential read/write performance at QD1 was found to be 2,096/1019 MB/s, which is solid. Random 4K QD1 performance was 50 MB/s read and 222 MB/s write. Those 4K random performance numbers improved up to 121 MB/s read and 387 MB/s write at a queue depth of 2.
