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: On ATTO Disk Benchmark we see that the Sabrent Rocket Q 1TB SSD reached speeds of up to 3.19 GB/s read and 1.86 GB/s write at a Queue Depth of 4. This drive is rated at reached speeds of up to 3.2 GB/s read and 2.0 GB/s write, so we are touch below that here when testing this SSD as a primary drive. 

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.


Benchmark Results: The Sabrent Rocket Q 1TB drive maxed out at 3259.70 MB/s read and 2080.45 MB/s write in the standard sequential write test that is done at Q8T1. Random 4K performance topped out at 176,634 IOPS read and 375,845 IOPS write. This drive is rated at 3,200 MB/s read and 2,000 MB/s write for sequential performance, so we were finally able to hit those numbers by using CrystalDiskMark!  The Rocket Q is rated for up to 125,000 IOPS read and 500,000 IOPS write and we are doing better than the Random 4K read performance rating, but aren’t coming close on the write side.  

Let’s look at some other benchmarks!
