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 – Kingston UV400 480GB:

Kingston UV400 480GB ATTO Benchmark

Benchmark Results: ATTO showed the Kingston UV400 480GB SSD maxing out at 562 MB/s read and 532MB/s write in the standard overlapped I/O benchmark. 


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 – Kingston UV400 480GB:

Kingston UV400 480GB CrystalDiskMark Benchmark

Benchmark Results: The Kingston UV400 480GB drive reached 555 MB/s read and 528MB/s write in the standard sequential write test. The Random 4K performance on the UV400 480GB drive was 36 MB/s read and 127 MB/s write. When we ran the test again set to 0Fill mode we saw some of the sequential read measurement peaked at 562MB/s! 

Let’s look at some other benchmarks!
