We ran two benchmarks using PCMark 10: the Full System Drive Benchmark as well as the Data Drive Benchmark. This review is likely PCMark 10’s last time being included in my SSD reviews, so enjoy it while it lasts!
The Rocket Q 2TB lands a little low on this benchmark, compared to where it has been placing on previous tests.
For the Data Drive benchmark, the Rocket Q 2TB shoots to nearly the top of the chart, even beating out some PCIe 4.0 based drives.
SPECworkstation 3.0.2 Storage Benchmark
SPECworstation benchmark is an excellent benchmark to test systems using workstation type workloads. In this test, we only ran the Storage component, which is 15 separate tests.
The Rocket Q 2TB manages an overall improvement compared to the 500GB drive, and a decent showing among PCIe 3.0 drives.
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, and is thus not representative of a cramped low-airflow case.
The Rocket Q 2TB keeps temperatures reasonable and should have no thermal problems in most common deployment scenarios.
Rocket Q 2TB vs 500GB
We wanted to take a moment and specifically point out the benefits of the more populated controller channels and cache area when moving to a higher capacity SSD, and so a direct comparison to the Rocket Q 500GB seemed appropriate.
As you can see, the larger Rocket Q 2TB beats out its 500GB brother by a significant margin in nearly every test. Considering that these drives are otherwise identical, these differences come entirely from having more controller channels populated and the larger psuedo-SLC cache area. If you need high performance from your SSD, sometimes you might have to purchase more capacity in order to get to that performance level.
For a 2TB NVMe SSD, the Rocket Q 2TB is among the least expensive at around $250. The larger capacity of the drive helped improve upon the performance we experienced when we tested the 500GB version of the drive, but the Rocket Q remains a QLC drive and still has the potential for some dramatic swings in write performance, especially as the drive fills up. As we tested it though, the drive performed very well.
The Rocket Q line is focused on users that need a good amount of SSD capacity at a reasonable price point, and the 2TB unit succeeds in that goal. All QLC based drives suffer potentially worse performance than the TLC and MLC based predecessors, but the storage efficiency of QLC has been directly translated into more capacity per dollar. If your usage profile is heavily write based, QLC drives are likely inappropriate as a whole, but for many uses the good read performance and high capacity will be highly valued. At 2TB, it is also a capacity point where another segment of users can pass on hard drives for SSDs. For those users, the Rocket Q 2TB should be given serious consideration.
