Benchmarks: AS SSD Benchmark
AS SSD Benchmark's sequential read/write performance matches what we saw when testing with CrystalDiskMark.
When measuring 4K-64 thread performance, the Extreme Pro is able to match the 850 Pro, placing it among the fastest SATA SSDs we have tested.
Despite its strong 4K-64 thread read performance, the Extreme Pro was much weaker when measuring write performance, delivering just 236MB/s -- 23% slower than the 850 Pro.
The Extreme Pro's read access wasn't particularly fast by SSD standards at 0.081ms whereas the 850 Pro for example took just 0.045ms while all other high performance SSDs take less than 0.060ms.
The write access time performance of the SanDisk Extreme Pro is also quite slow when compared to other SSDs.
