Samsung 990 EVO 2TB Performance Testing
We test using both the default smaller test size as well as larger test sets on our benchmarks. This allows us to see the difference between lighter and heavier workloads.
CrystalDiskMark is used as a basic starting point for benchmarks as it is something commonly run by end-users as a sanity check.
The Samsung 990 EVO 2TB hits its rated 5000 MB/s sequential read mark, but misses its rated 4200 MB/s write speed by a good bit. Compared to other drives on our list, you can see the 990 EVO trailing behind the top-end Gen 4 drives but keeping up with some more budget-oriented models. I only have a 250 GB version of the 970 EVO Plus in my testing database, so the comparison is somewhat unfair, but the 990 EVO does beat the drive by a fair margin.
The larger CrystalDiskMark test shows a small improvement in write speed for the 990 EVO 2TB, but it is still off the rated mark by around 400 MB/s. With that said, performance is still generally acceptable here.
ATTO Disk Benchmark
The ATTO Disk Benchmark has been a staple of drive sequential performance testing for years. ATTO was tested at both 256MB and 8GB file sizes.
ATTO results commonly come in slightly slower than CrystalDiskMark, and on the 990 EVO that is exactly what we see. Once again, write performance is a bit behind where I would expect given the advertised 4200 MB/s write speed, but not catastrophically far behind.
The larger ATTO test is nearly identical to the previous result. One note here: the 990 EVO performance was completely stable across the entirety of the ATTO testing, which is very positive for performance consistency.
Anvil’s Storage Utilities
Anvil’s Storage Utilities is a comprehensive benchmark that gives us a very in-depth look at the performance of the drives tested. This benchmark was run with both a 1GB and 8GB test size.
Anvil results show the Samsung 990 EVO beating out older or lower-end Gen 4 drives like the P3 Plus, while still trailing behind the drives that push the Gen 4 envelope.
The Samsung 990 EVO 2TB holds its scores very well on the larger Anvil test, dropping only a small step on the write score. The 990 EVO’s positioning on the graph is holding steady.
AS SSD Benchmark
AS SSD Benchmark is another good benchmark for testing SSDs. We run all three tests for our series. Like other utilities, it was run with both the default 1GB as well as a larger 10GB test set.
In AS SSD results, the 990 EVO squeaks out a win over the P5 Plus and lands in the middle of the chart. Given the specs, this is expected as the 990 EVO is essentially aiming for middle-of-the-road performance relative to other Gen 4 drives.
The 990 EVO performance holds out better on the larger AS SSD test than several other drives. I would give the 990 EVO the performance crown over both the Kioxia XG8 and the Fanxiang S880.
