Sabrent Rocket 4 Plus 4TB — High-Capacity PCIe 4.0 TLC NVMe (2026)
The Sabrent Rocket 4 Plus 4 TB is the flagship of Sabrent's TLC PCIe 4.0 lineup — the same Phison E18 performance as the 2 TB but with double the capacity and a 2,800 TBW endurance rating that rivals enterprise drives.
Controller & Memory
The 4 TB Rocket 4 Plus uses the Phison PS5018-E18 8-channel controller with sixteen Micron 96-layer TLC NAND packages and SK Hynix DDR4 DRAM on a double-sided M.2 2280 PCB. The massive NAND die count gives the E18 controller deep queues for interleaved writes, maintaining the same 7,100/7,000 MB/s rated performance as the 2 TB model while offering double the storage and endurance.
A double-sided PCB at 4 TB means this drive will not fit in single-sided-only M.2 slots found in some thin laptops and compact systems. For desktop motherboards and the PS5, clearance is generally not an issue with the bare drive. Sabrent offers optional heatsink variants, though for PS5 use you may need to use a low-profile heatsink to meet Sony's 11.25 mm height requirement.
At 4 TB, the Rocket 4 Plus competes with the Samsung 990 Pro 4 TB and the WD Black SN850X 4 TB. All three deliver similar PCIe 4.0 performance at the top of the consumer market. The Sabrent\'s appeal is typically a lower street price on Amazon while offering equivalent real-world performance and competitive endurance ratings.
Sabrent offers the Rocket 4 Plus with an optional heatsink. The Phison E18's 12 nm process runs cooler than the older E16, but sustained write loads still benefit from active cooling. For PS5 installations, the bare drive with a low-profile heatsink is the recommended configuration.

Rocket 4 Plus Performance & Benchmarks
The 4 TB Rocket 4 Plus is rated at 7,100 MB/s sequential reads, 7,000 MB/s sequential writes, 650K random read IOPS, and 1,000K random write IOPS — matching the 2 TB model. The large NAND array means the pseudo-SLC cache can absorb an enormous amount of data before exhausting: independent testing of E18-based 4 TB drives shows the cache handling 200+ GB of sustained writes before transitioning to native TLC speeds, sustaining approximately 1,500–2,000 MB/s.

- Patriot Viper PV573 2 TB: 14,000 MB/s read, 12,000 MB/s write
- Sabrent Rocket 4 Plus 4 TB (this drive): 7,100 MB/s read, 7,000 MB/s write
For gaming at 4 TB, the Rocket 4 Plus can hold 30–40 large AAA titles with room for the OS and applications. Game load times are identical to the 2 TB model and indistinguishable from the Samsung 990 Pro in real-world testing. Content creators benefit from the capacity for large project storage and the sustained write performance for video rendering, 4K/8K capture, and batch photo editing workflows. For gaming at 4 TB, the combination of read speed, random I/O performance, and DirectStorage compatibility means this drive handles anything current-generation games can throw at it. Content creators benefit from both the capacity for project storage and the sustained write bandwidth for video rendering workflows.

Endurance, TBW & Warranty
The Sabrent Rocket 4 Plus 4 TB is rated for 2,800 TBW endurance — the highest in the consumer Rocket lineup — backed by a five-year warranty with product registration. At 2,800 TBW, you can write approximately 1,534 GB per day over five years before hitting the rated limit. Even a professional content creator writing 500 GB daily would take over 15 years to exhaust the endurance. This is a drive designed to outlast its warranty period by a wide margin. S.M.A.R.T. health monitoring is supported, and Sabrent includes Acronis True Image for drive migration.

Verdict: Is the Rocket 4 Plus Worth It in 2026?
The Sabrent Rocket 4 Plus 4 TB is a no-compromise high-capacity NVMe drive for users who want both maximum speed and maximum storage in a single M.2 slot. Its 7,100/7,000 MB/s speeds match the 2 TB model, and the 2,800 TBW endurance rating is best-in-class for consumer TLC. The double-sided PCB limits laptop compatibility, and the warranty registration requirement is an annoyance. Against the Samsung 990 Pro 4 TB, the Sabrent offers equivalent performance at typically lower pricing. For a desktop or PS5 build where you want one drive to hold everything — OS, game library, creative projects, media — the Rocket 4 Plus 4 TB is among the best options available.
