Sabrent Rocket 4 Plus 1TB 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 Rocket 4 Plus didn’t quite manage to hit its rated sequential read and speeds, but it was not far off. Writes are nearly a tie with the similar FireCuda 530, with read speed trailing by just a bit.
Moving to the larger CrystalDiskMark benchmark helps out a lot; the read speeds improve to the point that they essentially match the ratings. As a result, the Rocket 4 Plus is now in a functional tie with the FireCuda 530. Spoiler alert, that is not the only time that will happen in this review!
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.
In ATTO read speed manages to match the CrystalDiskMark numbers, while write speeds take a small hit. With that said, the hit to write speed is not nearly as severe as the FireCuda, allowing the Rocket 4 Plus to beat it. Despite appearing in the 4th place slot on our chart, the Rocket 4 Plus is essentially tied for the best result on this chart.
That is better; the chart placement of the Rocket 4 Plus now accurately reflects its performance. There is essentially a 3-way tie for the top spot on this chart, and the Rocket 4 Plus is among them.
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, performance for the Sabrent Rocket 4 Plus is great and is once again a near-tie with the FireCuda 530. Both Phison-powered drives lose out to the WD SN850 very slightly in read score, but dominate the write score side.
In the larger Anvil test the Rocket 4 Plus is chart-topping for write score, beating the FireCuda 530 by a moderate margin. Read score is also good, though not quite able to beat out the SN850 and P41.
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 Sabrent Rocket 4 Plus puts in another good showing in AS SSD, slightly beating out the FireCuda 530 in write score.
Performance in the larger AS SSD test once again mirrors the FireCuda 530, with the Rocket 4 Plus slightly behind in read score and slightly ahead in write. Write score is easily top of the chart, though read score comes in behind several other models.
SPECworkstation, thermals, and our conclusion are up next.
