AIDA64 Disk Benchmark
Many enthusiasts are familiar with the Finalwire AIDA64 benchmark suite (formerly Lavalys EVEREST), but very few are aware of the Disk Benchmark tool available inside the program. The AIDA64 Disk Benchmark performs linear sequential tests on each drive, and does not require a partition to be present for testing so all of our benchmarks are completed prior to drive formatting.
Linear sequential disk tests scan from the first physical sector to the last, and could be considered the best measure of storage performance. A side effect of many linear write-performance test tools is that the data is erased as it writes to every sector on the drive. Normally this isn’t an issue, but it has been shown that partition table alignment will occasionally play a role in overall SSD performance (HDDs don’t suffer this problem).
AIDA64 Sequential Reads: Intel X99 Platform
AIDA64 Sequential Reads: Intel Z170 Platform
Lavalys AIDA64 Disk Benchmark utilized a 1MB block size to test the 512GB Samsung SSD 950 PRO. As illustrated in results above, read performance with 950 PRO on the X99 test system measured average speeds of 2310 MB/s while the Z170 platform produced 2166 MB/s.
Tests on the X99 system delivered consistent flat-line wave form results, allowing for an average read speed virtually identical to this drive’s maximum peak speed across the full capacity. Z170 results delivered rather inconsistent sequential performance, with the average and maximum speeds separated by 110 MB/s.

AIDA64 Sequential Writes: Intel X99 Platform (DISKPART Clean)
AIDA64 Sequential Writes: Intel X99 Platform (Magician Secure Erase)
AIDA64 Sequential Writes: Intel Z170 Platform
The waveform charts above illustrate buffered data writes on 950 PRO, indicating linear write performance speeds saturated the transfer cache. The 512GB Samsung SSD 950 PRO solid state drive recorded an average linear write-to speed of 916 MB/s on X99 using DISKPART clean -all NAND prep and 978 MB/s using Magician Secure Erase. This is a remarkable deviation, as maximum performance reached 1492 MB/s for a difference of 576 MB/s.
Test performance on the Z170 system appeared less volatile as the write speeds averaged 1349 MB/s while maximum speed reached 1507 MB/s, for a difference of 158 MB/s.
