Sabrent Rocket Q4 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 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.

The Sabrent Rocket Q4 2TB starts off strong, and exceeds its rated sequential read and write specifications by a small amount. The only drives to beat it are the Samsung 980 Pro 500GB and Sabrent’s performance flagship the Rocket 4 Plus.

Moving to the larger 8GB shows the Rocket Q4 2TB holding strong, with no change in the observed sequential transfer performance from the smaller test.

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.

Performance in ATTO is good as well, with the Rocket Q4 2TB again punching above its weight in read performance, and matching its rated specs for writes.

The larger test has a negligible effect on the Rocket Q4 2TB, which is a good thing.

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.

Were it not for the recently reviewed Samsung 980 Pro and Sabrent Rocket 4 Plus, the Rocket Q4 2TB would be taking the top spot for both read and write score in Anvil. Even in the context of those two drives, the Rocket Q4 is a strong performer, and Phison-based drives always do well in Anvil’s write tests in particular.

The larger Anvil test set finally makes an impact on the Sabrent Rocket Q4 2TB, and knocks it down several pegs on the read performance relative to the rest of our benchmark pool. Write scores still remain unchallenged by all but the Rocket 4 Plus.

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.

Thanks to the relatively lackluster performance of the Samsung 980 Pro 500GB in this test, the Sabrent Rocket Q4 2TB manages a solid second-place finish overall in AS SSD’s 1GB test.

Similar to the results in Anvil, the larger AS SSD test set knocks the Sabrent Rocket Q4 2TB down a few spots. The results are still good, just not chart-topping.

SPECworkstation, direct comparisons, thermals, and our conclusion are up next.

  1. I’m very happy about any storage review, but I surprised to see so many reviews on non-pro storage (QLC and DRAM-less) here on STH. There are a lot of interesting “server” storage that could be interesting to have a closer look at. Seagate have a lot of pro and semi-pro drives for example.
    Another thing I would really appreciate included is SQL performance benchmarks.
