Sabrent Rocket Q 2TB Performance Testing
We are moving towards using larger test sizes on our benchmarks, but on several tests, we also used the smaller default test size. This allows us to see the difference between lighter and heavier workloads.
BlackMagic Disk Speed Test
This is a popular speed test in the video community. It shows whether a storage device is suitable for throughput required at a given video format.
As a PCIe 3.0 NVMe SSD, the Rocket Q 2TB has a good showing here and handles every format this benchmark can test for.
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.
Using the 1GB test set, the Rocket Q 2TB hits all its advertised speeds, and actually manages to top the charts among the PCIe 3.0 SSDs we have tested.
Moving to an 8TB test set, the Rocket Q 2TB is unaffected by the change.
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.
Compared to CrystalDiskMark, ATTO’s read and write performance is a tick slower but not by much. Overall there is strong performance here compared to the rest of the PCIe 3.0 crowd.
We generate our graph data from the 32MB chunk size datapoint of ATTO, but looking at the whole graph you can see some wild swings in write speed. Overall though, performance was much improved compared to the Rocket Q 500GB thanks to the larger SLC write cache area.
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.
As with many drives we have recently tested, Anvil tends to show lower read performance than either ATTO or CrystalDiskMark, while write speeds trend closer to those other testing utilities. Overall the Rocket Q 2TB has a good showing here and easily smashes its little brother.
With 8GB test size, writes speeds dipped a bit under the heavier queue depth loads. TLC-based SSDs like the Samsung and Rocket NVMe drives fare better here.
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.
The Rocket Q 2TB manages to top the PCIe 3.0 charts again, with a good margin of victory on the read speed and only being narrowly edged out in write speed by the Rocket NVMe 512GB unit. This is due in large part to the more populated controller on the Rocket Q 2TB, and if the Rocket NVMe was a larger capacity drive it would likely beat out the QLC based drive.
The larger AS SSD test set tends to dramatically affect performance of the consumer class SSDs we test, and the Rocket Q 2TB is no different in that regard. It holds up reasonably well, and much better than the 500GB version of the drive, but still takes a big dip compared to the smaller version of this benchmark.
PCMark, SPECworkstation, and our conclusion are up next.
