ATTO & CrystalDiskMark

ATTO v4.01.0f1

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 Disk Benchmark:

Benchmark Results: On ATTO Disk Benchmark found that the XPG GAMMIX S50 Lite 1TB NVMe SSD topped out at 3.51 GB/s write and 2.90 GB/s read at the standard queue depth of 4. There were a few really low scores as you can see from the chart above and this was the case with and without write cache being enabled and on two different SSD firmware versions. 


This chart is getting pretty messy, but we are charting the 128KB results and ranking them high to low with the write result. The XPG GAMMIX S50 Lite is pretty much in the middle of the pack for sequential performance on this popular benchmark.

CrystalDiskMark 7.0.0 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) and shows the highest score of five runs.


Peak Performance Preset

Real Performance Preset

Benchmark Results: The XPG GAMMIX S50 Lite 1TB drive came in with scores of 3846.52 MB/s read and 2950.68 MB/s write on CrystalDiskMark 7. According to the datasheet for the XPG S50 Lite, this drive is rated at up to 3,900 MB/s read and 3,200 MB/s write for this benchmark, so we are very close to the expected read speed and about 8% lower than expected on the write speeds. Drive performance will vary depending on the platform and components being used, so this is not unusual by any means.

Let’s look at some other benchmarks!
