Sabrent Rocket 4 Plus Spec and Price in the United States
$409.99 MSRP
Step down a PCIe generation from the Rocket 5 and Sabrent's Rocket 4 Plus lands in more familiar mainstream territory: 7,100/6,600 MB/s sequential, a Phison PS5018-E18 controller, and DRAM cache, at roughly two-thirds the price of its PCIe 5.0 sibling. Random performance is rated at 650,000/700,000 IOPS, and the 1,400TB endurance rating comfortably outlasts typical desktop or light workstation use over its 5-year warranty. It reads as the balanced middle child of the three Rocket drives — quick enough for gaming and content work without the platform requirements of PCIe 5.0.
Tied 30th of 106 models in the SSD catalog on Sequential read — 4 models share this figure. Tied 24th of 106 models in the SSD catalog on Sequential write — 4 models share this figure.

What owners and reviewers say
Summarised from 1 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- Reviewers rate its overall PCIe 4.0 performance solid, with a strong large-block sequential read placing among the highest tested.
- It offers an optional heatsink to curb thermal throttling, bundled imaging software and a five-year warranty when registered.
Commonly criticised
- The 1TB and 2TB models are priced high, and measured performance fell short of Sabrent's quoted sequential read ceiling.
- It posted one of the weaker 4K random read results and took sharp latency dips in some workloads.
