# 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.

Quick answer: 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.

## Performance

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.

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.

## Pros and Cons

**Pros:**

- 7,100 MB/s reads, 7,000 MB/s writes at 4 TB capacity
- 2,800 TBW endurance — best-in-class for consumer TLC
- Large pseudo-SLC cache absorbs 200+ GB writes
- Micron 96L TLC NAND with strong sustained writes
- 1 million random write IOPS
- Competitive pricing vs Samsung 990 Pro
**Cons:**

- Double-sided PCB limits laptop compatibility
- Warranty drops to 1 year without registration
- No included heatsink (optional variant available)
- No hardware AES 256-bit encryption
- Premium pricing tier — not a budget option


## Verdict

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.

## Frequently Asked Questions

### Is the Sabrent Rocket 4 Plus 4TB good for gaming?

At 4 TB, this drive can store 30–40 AAA titles alongside the OS with room to spare, and the 7,100 MB/s read speed means game loads are as fast as any consumer SSD on the market. Random read performance and DirectStorage compatibility are top-tier. For a single-drive gaming PC, this is essentially the maximum capacity and performance available in a single M.2 slot without stepping up to PCIe 5.0.

### Is the Sabrent Rocket 4 Plus 4TB compatible with the PS5?

Yes, with caveats. The 7,100 MB/s reads exceed Sony's 5,500 MB/s recommendation. The bare drive fits within the PS5's M.2 bay dimensions. However, the 4 TB model uses a double-sided PCB that adds thickness, and if you use the heatsink variant, verify the total height stays under Sony's 11.25 mm limit. Remove Sabrent's heatsink if needed and use a low-profile PS5-compatible heatsink. Performance in PS5 games is excellent.

### What is the TBW endurance of the Sabrent Rocket 4 Plus 4TB?

The 4 TB model is rated at 2,800 TBW (terabytes written), backed by a five-year warranty with registration. This is approximately 1,534 GB of writes per day for five years. For perspective, a gaming desktop typically writes 30–60 GB/day, and even a professional content creator rarely exceeds 500 GB/day. The endurance headroom is massive — the drive is designed to outlast the warranty period comfortably regardless of workload.

### Does the Sabrent Rocket 4 Plus 4TB fit in a laptop?

The 4 TB model uses a double-sided PCB with NAND packages on both sides, making it thicker than single-sided drives. Many thin laptops and ultrabooks only support single-sided M.2 modules. Gaming laptops and workstation-class notebooks with full-height M.2 bays should accommodate it. Check your laptop's specification for M.2 slot height (single-sided vs. double-sided) before purchasing.

### How does the Sabrent Rocket 4 Plus 4TB compare to the Samsung 990 Pro?

Both deliver top-tier PCIe 4.0 performance at 4 TB. The Samsung uses its in-house Pablo controller and V-NAND, while the Sabrent uses the Phison E18 and Micron TLC. Real-world performance differences are negligible for gaming and desktop use. The Samsung has a standard five-year warranty without registration requirements; the Sabrent requires registration within 90 days. The Sabrent typically sells for less on Amazon. Both support PS5; both are excellent choices.

### Is the Sabrent Rocket 4 Plus good for video editing and content creation?

The 4 TB model is arguably the best capacity for content creators. The 7,000 MB/s writes handle 4K and 8K footage imports, the large pseudo-SLC cache buffers massive render jobs, and the 2,800 TBW endurance tolerates the heavy write workloads that video editing generates. At 4 TB, you have space for OS, applications, active projects, and a substantial media library on one drive. For professionals who want a single-drive solution, this is an excellent choice.
