ATTO & CrystalDiskMark

ATTO v4.00.0f2

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: ATTO Disk Benchmark had the SK Hynix 1TB drive reaching speeds of up to 537.06 MB/s read and 505.26 MB/s write at a Queue Depth of 4. This is slightly below the drives rated sequential read/write speeds of 560/525 MB/s.

CrystalDiskMark 7.0.0 RC 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.


Benchmark Results: The SK Hynix S32 Gold 1TB drive topped out at 561.55 MB/s read and 528.48 MB/s write in the standard sequential write test that is done at Q8T1. This drive is rated at being up to 560 MB/s read and 525 MB/s write, so we were able to exceed both of those ratings. Random 4K Q1T1 performance was 21.01 MB/s read and 59.60 MB/s write. 

Let’s look at some other benchmarks!
