SATA Express Performance on ASUS Hyper Express Drive


ATTO & AS-SSD Benchmarks

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 – Overlapped I/0:


Benchmark Results: ATTO showed the ASUS Hyper Express maxing out at 729 MB/s read and 474MB/s in the standard overlapped I/O benchmark.

AS-SSD (1.7.4739.38088) Benchmark:

We have been running the AS-SSD Benchmark app for over some time now and found that it gives a broad result set. The programmer has worked very hard on this software and continues to make updates often so if you use it, show him some love and send him a donation. There are now three tests that are found within the tool and we’ll show the results from all three of them.



Benchmark Results: AS SSD showed the ASUS Hyper Express SATAe enclosure topping out at 631.15 MB/s read and 454.68 MB/s write in the sequential benchmark. The copy benchmark showed the speed topping out at 332.54 MB/s in the three tests, which is a littler lower than we were hoping for.


Benchmark Results: Performance on the ASUS Hyper Express didn’t appear to be very consistent when it came to compressible data as the write scores were all over the place and even dropped down near 100MB/s for a brief second.
