SanDisk Extreme Pro & WD Black M.2 NVMe SSDs Review (1TB) – 3.4GB/s and 500K IOPS


The AJA Video Systems Disk Test is relatively new to our testing and tests the transfer speed of video files with different resolutions and Codec. This is the result of testing with WD Black.


For our Real World File Transfer Comparison, we have included the Intel Optane 900PSamsung 960 ProHP EX920 NVMe SSD and Toshiba RD400 in our testing with the SanDisk Extreme pro and WD Black 1TB NVMe SSDs. This test is conducted through the transfer of data from one spot on the test drive to another to give us the truest of transfer speed results for that device.

In testing the SanDisk Extreme Pro and WD Black NVMe SSDs, we can see that both had faster transfer times for video, music and photos than the Samsung 960 Pro and, in fact, these three transfer tests were pretty much equal with the Intel Optane.  No other SSD has come close to doing this before today and this speaks very highly for the WDBlack and SanDisk Extreme Pro.


It has been about a year and a half since Samsung released its 960 Pro NVMe SSD and it has had a foothold on the industry.  It has literally been top dog and the only thing that might make anyone look elsewhere would be the Optane, the Optane having far superior performance but the inability to pack any decent capacity into an M.2 SSD.  That has literally been Optane’ Achilles Heal.

Our introduction of the SanDisk Extreme Pro and Western Digital NVMe SSDs today brought with it superior performance in both throughput and IOPS and benchmarks that, but for the read IOPS coming up a bit short, places both of these SSDs with the best.  3.4GB/s read and 2.8GB/s write along with 500K read IOPS and 400K write IOPS are just about as good as it gets in the SSD industry for an M.2 SSD right now. If you are looking for performance in pure data transfer, look no further than our true data transfer testing where both of these SSDs moved data faster than the Samsung 960 Pro.

WD/SanDisk makes this even more attractive with a 5-year limited warranty and, to top it all off, they made sure they undercut the Samsung 960 Pro NVMe SSD, the only SSD that provides any real competition for the speed and quality that these SSDs exhibit.  They never undercut that price by a few bucks , but rather, we are seeing MSRP for the 500GB version almost $100 cheaper than the Samsung, and the 1TB version just under $200 cheaper.  Those are some dynamite price points.  The only thing more we might have asked for would be a 2TB capacity as well.

So… Build… check… Performance… check … Warranty… check … SanDisk SSD Dashboard… Check… Pricing… Check! Check! Check! So long as retailers don’t through on a premium at their end.  Editor’s Choice.
