ADATA Ultimate SU800 512GB 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.


ADATA SU800 512GB ATTO Benchmark

Benchmark Results: ATTO showed the ADATA SU800 Ultimate 512GB SSD topped out at 564 MB/s read and 519MB/s write in the standard overlapped I/O benchmark. ADATA rates this particular model at up to 560 MB/s read and 520 MB/s write, so we are close to the rated speeds. 


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.

ADATA SU800 512GB CrystalDiskMark Benchmark

Benchmark Results: The ADATA SU800 512GB drive reached 550 MB/s read and 509 MB/s write in the standard sequential write test. The Random 4K performance on the SU800 512GB drive was 37 MB/s read and 137 MB/s write. When we ran the test again set to 0Fill mode and all the scores remained basically the same as you can see above.  

Let’s look at some other benchmarks!

    The review says ” The ADATA Ultimate SU800 512GB drive performs like most any TLC NAND based value SSD and needs a lower price point to be a recommended pick!”
    Yet, in what is arguably the most difficult test, the Sustained Write test, it performed among the top four. Two of the other top performers, the Samsung 850 EVO and OCZ VX500 both cost 25% to 35% more at Amazon and Newegg. Only Crucial’s MX300 matched the ADATA for both price and performance. Four other TLC drives tested all fell well short of the ADATA’s performance and cost about the same. So, the review’s bottom line is a damn-it-with-faint-praise throwaway which signally fails to reflect the SU800’s solid achivement. I call that obvious negative bias.

  • Starvin Marvin

    Your description of the SU800’s sustained write performance is damning it with faint praise. For a budget-sector consumer TLC-based drive to sustain a high Write for over 170GB is truly outstanding. At the very least you should emphasize that home users are unlikely to EVER encounter any drop-off in Write speed with this SSD.


    Sustained Write-
    My calc says-342 sec x 521MB =178182MB =174GB

    why no physical teardown showing inside of drive

    • It would physically destroy the drive due to their choice of construction
