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 shows that the SAMSUNG XP941 256GB M.2 SSD has some very impressive performance numbers for a used primary drive, it was able to hit 784MB/s read and 460MB/s write! These are a bit off from the 1080MB/s read and 800MB/s write speeds advertised by Samsung, but these are real world results!

 

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.

asssd-copy

Benchmark Results: In AS SSD the Samsung XP941 256GB M.2 SSD topped out at 682.54MB/s read and 388.93MB/s write during the sequential benchmarks. Looking at the AS SSD Copy benchmark the Samsung XP941 M.2 PCIe SSD had a solid performance of 402.18MB/s.

asssd-compression

Benchmark Results: The compression benchmark performance of the Samsung XP941 M.2 256GB SSD was pretty consistent along the entire test, there’s going to be some slight variations but nothing that we saw should give any reason for concerns.
