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 the Lexar NM610 1TB drive topped out at 1.93 GB/s read and 1.60 GB/s write on the standard test at QD4. This drive is rated at 2.10 GB/s read and 1.60 GB/s write, so we were close to the drives rated speeds.
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 Lexar NM610 1TB drive maxed out at 2,051.28 MB/s read and 1,673.22 MB/s write in the standard sequential write test that is done at Q8T1. Random 4K performance topped out at 236K IOPS read and 239K IOPS write. Random 4K performance at QD1 was 57.52 MB/s read and 183.24 MB/s write.
