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 both Crucial MX drives reaching speeds of up to 564 MB/s read and 524 MB/s write on the 500GB drive and 519 MB/s on the 1TB drive in the standard overlapped I/O benchmark. This drive is rated at up to 560 MB/s max sequential read and 510 MB/s max sequential write, so we exceeded both of those scores on our Intel Z370 based test platform.
Benchmark Results: Compared to some other SATA III SSDs we can quickly see that there isn’t much difference with regards to sequential read performance. The Crucial MX500 drives has solid performance compared to the other brands and series.
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 Crucial MX500 500GB reached 563 MB/s read and 522 MB/s write in the standard sequential write test. Random 4K QD1 performance was 43 MB/s read and 105 MB/s write. Those 4K random performance numbers improved up to 223 MB/s read and 205 MB/s write at a queue depth of 32. The Crucial MX500 1TB benchmarked just slightly slower than the 500GB drive, but was still well within rated speeds.
