Samsung 980 1TB Performance Testing
We are moving towards using larger test sizes on our benchmarks, but on several tests, we also used the smaller default-test sizes. This allows us to see the difference between lighter and heavier workloads.
CrystalDiskMark 7.0.0 x64
CrystalDiskMark is used as a basic starting point for benchmarks as it is something commonly run by end-users as a sanity check.
Right off the bat, the sequential performance numbers for the Samsung 980 1TB are just a bit below the advertised rates. Do not get me wrong, the performance here is pretty darn good for a PCIe 3.0 SSD, but it does not quite live up to the advertised 3500MB/s read and 3000MB/s write rates. As far as relative positioning, the 980 1TB arrive right in line with other quality PCIe 3.0 SSDs.
Moving to the larger CrystalDiskMark test has absolutely no effect on the Samsung 980 1TB. Sequential numbers are still just a tick below the advertised rates.
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.
Results in ATTO are a mirror of those in CrystalDiskMark; good performance that is just below the advertised rates. Of note here is that the 980 1TB is consistently just a hair behind the older 970 EVO Plus on read speeds.
Much like CrystalDiskMark, the larger ATTO test has negligible impact on the 980 1TB’s sequential rates.
Anvil’s Storage Utilities
Anvil’s Storage Utilities is a comprehensive benchmark that gives us a very in-depth look at the performance of drives tested. This benchmark was run with both a 1GB and 8GB test size.
In Anvil, the Samsung 980 1TB lands squarely in the middle of our benchmark pack, though trending towards the upper end of the PCIe 3.0 crowd. Notable here is the write performance, which is especially admirable given the lack of a DRAM cache.
Finally, we have a minor bit of movement from the larger test set, with the 980 1TB losing a bit of ground on the write score relative to the smaller test. Overall though, the drop is minor and does not really affect the relative positioning of the drive on our chart.
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, the Samsung 980 1TB pulls off its first victory among the PCIe 3.0 crowd, narrowly edging out some of the other drives.
The good fortune is not to last though, as moving to the larger AS SSD test showcases a somewhat precipitous drop in write score for the 980 1TB. The bulk of the loss comes from dramatically slower 4K-64 Thread results.
SPECworkstation, direct comparisons, thermals, and our conclusion are up next.
