ADATA Premier SP550 120GB, 240GB and 480GB SSD 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 ADATA SP550 120GB SSD maxing out at 559 MB/s read and 422MB/s write in the standard overlapped I/O benchmark. The larger SP550 240GB drive topped out at 561 MB/s read and 511 MB/s write and lastly the 480GB drive hit 561 MB/s read and 515 MB/s write.  

 

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 ADATA SP550 120GB drive reached 547 MB/s read and 413MB/s write in the standard sequential write test versus the 549 MB/s and 490 MB/s seen on the large capacity drives. The Random 4K performance on the all of the SP550 drives that we tested were ~30 MB/s read and ~139 MB/s write. When we ran the test again set to 0Fill mode and the results were very similar. 

Let’s look at some other benchmarks!
