Samsung 990 Pro SSD Review – Samsung Reigns True Yet Again

CRYSTAL DISK BENCHMARK VER. 8.0.4 x64

Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

THROUGHPUT

IOPS

Throughput of 7.1GB/s read and 6.7GB/s write are great, however, read and write random 4K IOPS above 1.4 million IOPS is unbelievable.  The beauty of this test is seeing our first low 4K random read result above 100MB/s.  This is going to make all the difference in later testing.

AS SSD BENCHMARK VER 2.0

The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs.

ANVIL STORAGE UTILITIES PROFESSIONAL

Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

AJA VIDEO SYSTEM DISK TEST

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.

TxBENCH

TxBench is one of our newly discovered benchmarks that we works much the same as Crystal DiskMark, but with several other features. Advanced load benchmarking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting.

    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
