SanDisk Extreme PRO Series SSD Review


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 – Intel Z77 Platform:

Benchmark Results: Across the three SanDisk Extreme Pro drives, performance was pretty close in the writes department and the 240GB drive fell behind a bit in the reads. Overall, the two larger drives put up excellent numbers. All are an improvement upon the Extreme II drive.


AS-SSD (1.7.4739.38088) Benchmark – Intel Z77 Platform:

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 two of them.

Benchmark Results: Here all three drives perform equally and the overall score earns them a spot in the middle of the pack as the 4K write scores are lower than a handful of other drives as well as the Extreme II.

Benchmark Results: Compression has no bearing on performance as the charts show in this benchmark from AS-SSD.
