Samsung 990 Pro SSD Review – Samsung Reigns True Yet Again


PCMark 10 Storage Benchmarks produce an overall score as a measure of drive performance. Comparing devices is as simple as comparing scores. The tests also measure and report the bandwidth and average access time performance for the drive. Each test uses traces recorded while performing real-world tasks such as booting Windows 10, starting applications such as Adobe Photoshop and Illustrator, working with applications such as Microsoft Excel and PowerPoint, and copying several large files and many small files.

PCMark 10 results placed the Samsung 990 Pro just behind the Optane DC P5800x and well ahead of the rest of the pack.



The Quick System Drive Benchmark is a subset of the Full test and is more representative of typical daily usage to show what would be expected regarding hybrid SSD performance on a day-to-day basis.


Once again, we see the Samsung 990 Pro on top of all competitive SSDs in its class.



For our True Data Testing, we simply loaded 15GB video, music, photo and OS files onto the Samsung 990 Pro Gen 4 NVMe SSD and copied the data to a new folder on that same disk.   Is that right?  Did the 990 Pro just surpass the Optane?



We thought we might add a few extras in our report today, PassMark Performance Test DiskMark component being a nice addition.  This software tests sequential reads and writes, along with IOPS and compares the result with millions of other SSDs worldwide.  We might suggest being in the 99th percentile of all SSDs tested was a nice result.


Comparing the Samsung 990 Pro against other SSDs tested with Passmark, we can see that the 990 Pro sits in that ‘numero uno’ position with points to spare…



The Final Fantasy Benchmark is a new tool in our arsenal and geared specifically to the gamer.  The software is installed directly on the SSD and the SSD tested, providing and end result of FPS and scene transition times.


The Samsung 990 Pro has absolutely fantastic game load times in comparison.

    For the everyday use of an average user, is there any significant difference between Gen 4 NVMe SSD and Gen 5? Is it worth the expected price difference?

      For every day use for the average user any SSD would work. There isn’t an expert in the world that can tell the difference in any SSD during typical everyday use.

      That is basically same as asking if it is worth to buy pcie 4 gpu over pcie 5 gpu. It really depends on product and your use case. I would argue that you might see some improvement on games using direct storage, but there are a lot of if:s in that. I would also argue that you see noticeable difference on windows startup time if you go for intel optane 905 which is gen 3 vs any pcie 5 currently on the market. That has like 3x higher 4k read performance. Interface just enabled higher transfer speed, you need something on the other end that can actually use the available bandwidth on the other end. 14GB/s is not really worth it if device can do 100MB/s at 4k file size if that is your primary need. Personally I think pcie 5 SSD is waste of money because most use cases require higher small file reads, which are currently somewhere between 50MB/s and 350MB/s. Most SSD:s are below 100MB/s and optane:s were at bit above 300MB/s. Sadly Intel could not market them properly as they have max transfer speed below 3GB/s, while Samsung 990 is above 7GB/s. It is pretty hard for marketing team to say Intel one would be faster on overall use when most people just look at max transfer speed.

    100MB random reads? Thats huge speed. Unbelievable
