Next we ran SiSoft SANDRA 2017, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provide the results from our comparison SSDs. The benchmarks were run on clean drives that lacked any partions. Read and write performance metrics are detailed below.

Synthetic Disk Benchmarking

The Samsung SSD 970 Pro and 970 EVO led the pack here in reads, though the WD Black NVMe continues to put up some impressive write scores.

ATTO Disk Benchmark

ATTO is another "quick and dirty" type of disk benchmark that measures transfer speeds across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5KB through 64MB transfer sizes and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than I/O response time, access latency, etc.

We've got a mish-mash of data to digest here. The WD Black NVMe once again puts up strong writes with the larger transfer sizes, but trails the other drives in both reads and writes with smaller transfers. the Samsung SSD 970 Pro and 970 EVO edge out the previous-gen 960 Pro in the write test as you would expect, and lead the other drives. In the read test, the 960 Pro is able to pull ahead of the 970 EVO, but the 970 Pro finishes at the top of the heap.

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
