ATTO & CrystalDiskMark

ATTO v2.47

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 8192KB transfer sizes with the total length being 256MB.

ATTO – OCZ Trion 100 480GB:

OCZ Trion 100 ATTO

ATTO – Samsung SSD 850 EVO 512GB:


Benchmark Results: ATTO showed the OCZ Trion 100 480GB SSD maxing out at 563 MB/s read and 537MB/s write in the standard overlapped I/O benchmark. The Samsung SSD 850 EVO 500GB  topped out at 549 MB/s read and 533 MB/s write, but had much better write performance at lower transfer file sizes. For example at 512 Bytes the Samsung SSD 850 EVO 500GB drive was at 54 MB/s write while the OCZ Trion 100 480GB SSD was at 35 MB/s. 


CrystalDiskMark 3.0.4 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 – Samsung SSD 850 EVO 512GB:


Benchmark Results: The Samsung SSD 850 EVO 500B drive topped out at 539 MB/s read and 524 MB/s write on the sequential test whereas the OCZ Trion 100 480GB drive reached 552 MB/s read and 522 MB/s write. The real performance difference that is worth talking about is not in the sequential performance numbers though as it would be the Random 4K performance. The Samsung SSD 850 EVO 500GB had 51 MB/s read and 146 MB/s write on the 4K test versus 32 MB/s read and 124 MB/s write on the OCZ Trion 100. 

Let’s look at some other benchmarks!
