SPECworkstation 3.0.2 Storage Benchmark
SPECworkstation benchmark is an excellent benchmark to test systems using workstation-type workloads. In this test, we only ran the Storage component, which is fifteen separate tests.
SPECworkstation is interesting in terms of the comparison to the FireCuda 530; the Sabrent Rocket 4 Plus turns in near-identical results in all the tests except Energy where the Rocket takes a commanding lead. Overall the SPECworkstation performance here is great and the Rocket 4 Plus wins more benchmarks than it loses in comparison to the SK hynix Platinum P41.
Sustained Write Performance
This is not necessarily a benchmark, so much as trying to catch the post-cache write speed of the drive. While I am filling the drive with data to the 85% mark with 10 simultaneous write threads, I monitor the drive for the write performance to dip to the lowest steady point and grab a screenshot.
I crowned the FireCuda 530 the sustained-write king, but it looks like that throne will need to be shared. The Post-cache write speed on the Sabrent Rocket 4 Plus is amazing, and stands head and shoulders above almost everything else.
We monitored the idle and maximum temperature during testing with HWMonitor to get some idea of the thermal performance and requirements of the drive. Please keep in mind that our test bench is an open frame chassis in a 22C room, but with no direct airflow. As a result, this is not representative of a cramped low airflow case and is instead intended to model temperatures of a drive ‘on its own’.
The thin heatspreader on the Sabrent drive holds the temperature to 79C, which is too warm for my liking but not quite as catastrophic as drives that make it halfway through the 80s. Just as important, I did not observe throttling. Sabrent does offer an after-market heatsink if needed, though under lighter loads the Rocket 4 Plus likely will not require additional cooling unless your case is especially warm or cramped.
Today the Sabrent Rocket 4 Plus 1TB is $150 online. That price point is right in line with other top-end drives like the WD Black SN850, and is actually $10 less expensive than the current price for the Seagate FireCuda 530 without its heatsink. Given the performance achieved today, that pricing is perfectly in line with my expectations.
Up until now, I would have placed the FireCuda 530 as my favorite PCIe 4.0 drive, but Sabrent has decided to give Seagate some competition; the Rocket 4 Plus turns in performance that is overall slightly better than the FireCuda at a slightly lower price. Combined with the stellar sustained write performance and exemplary write endurance, the Rocket 4 Plus is a winner.
