Limited Edition 750GB Crucial MX300 SSD Review

ATTO & CrystalDiskMark

ATTO v3.05

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 – Crucial MX300 750GB:

Benchmark Results: ATTO showed the Crucial MX300 750GB SSD maxing out at 536 MB/s read and 514MB/s write in the standard overlapped I/O benchmark. Crucial rates this particular model at up to 530 MB/s read and 510 MB/s write, so that appears to be pretty accurate.

CrystalDiskMark 5.1.2 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) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.

CystalDiskmark – CrystalDiskMark 750GB:

Benchmark Results: The Crucial MX300 750GB limited edition drive reached 535 MB/s read and 513MB/s write in the standard sequential write test. The Random 4K performance on the MX300 750GB drive was 30 MB/s read and 140 MB/s write. When we ran the test again set to 0Fill mode we saw most of the read scores improve, but there wasn’t much of an increase on the writes.
