Samsung SSD 750 EVO 120GB and 250GB Review

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.

Benchmark Results: ATTO showed the Samsung 750 EVO 120GB SSD maxing out at 557 MB/s read and 530 MB/s write in the standard overlapped I/O benchmark. The Samsung 750 EVO 250GB SSD topped out at 557 MB/s read as well, but had a slightly higher 533 MB/s write speed.  

 

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.

Benchmark Results: The OCZ Trion 150 480GB drive reached 554 MB/s read and 527MB/s write in the standard sequential write test. The Random 4K performance on the OCZ Trion 150 480GB drive was 35 MB/s read and 122 MB/s write. When we ran the test again set to 0Fill mode we dound that the 4K read score shot up from 35 MB/s to 153 MB/s on the OCZ Trion 150. 

Let’s look at some other benchmarks!
