# Sabrent Rocket 4 Plus 2TB — High-Performance PCIe 4.0 NVMe (2026)

The Sabrent Rocket 4 Plus 2 TB is the capacity where this Phison E18 platform flexes its full muscle — 7,100 MB/s reads, 7,000 MB/s writes, and 1 million random write IOPS from Micron 96L TLC NAND with a 1,400 TBW endurance rating.

Quick answer: The Sabrent Rocket 4 Plus 2 TB is a top-tier PCIe 4.0 drive that belongs in any conversation about the best consumer NVMe SSDs. Its 7,000 MB/s writes and 1 million random write IOPS are enthusiast-grade numbers, and the 1,400 TBW endurance rating provides long-term confidence. The trade-off against Samsung and WD alternatives is mostly brand preference and warranty registration hassle — performance is functionally identical. For a single-drive gaming and productivity build where you want capacity, speed, and reliability in one package, the Rocket 4 Plus 2 TB is an easy recommendation. Just remember to register it within 90 days.

## Performance

With 7,100 MB/s sequential reads, 7,000 MB/s sequential writes, 650K random read IOPS, and 1,000K random write IOPS, the Rocket 4 Plus 2 TB delivers near-maximum PCIe 4.0 performance. The 1 million write IOPS figure is the highest in the lineup and reflects the deep queue depth the E18 controller can exploit with 2 TB of NAND to manage. Guru3D's testing of the 2 TB model found consistent performance across synthetic and real-world benchmarks, with the Sabrent trading narrow wins and losses with the Samsung 980 Pro depending on the specific test.

Sustained write performance is a strength. After the pseudo-SLC cache fills — which takes approximately 100–150 GB of continuous writes at full speed — native TLC writes sustain at roughly 1,200–1,800 MB/s. This is a much smaller performance cliff than QLC drives face, and for most users the cache rarely exhausts during normal use. Content creators working with 4K video and large RAW photo batches will find the sustained write performance adequate for professional workflows.

## Endurance, TBW & Warranty

The Sabrent Rocket 4 Plus 2 TB carries a 1,400 TBW endurance rating with a five-year warranty requiring product registration within 90 days. At 1,400 TBW, this works out to approximately 766 GB of writes per day over five years. For a 2 TB drive serving as both OS and game library, the actual daily writes are typically 30–80 GB, providing over a decade of rated endurance headroom. Even a professional content creator writing 300 GB/day would take nearly 13 years to exhaust the warranty limit. The drive supports S.M.A.R.T. health monitoring, and Sabrent includes Acronis True Image for drive migration.

## Pros and Cons

**Pros:**

- 7,100 MB/s reads, 7,000 MB/s writes saturate PCIe 4.0
- 1 million random write IOPS — highest in series
- 1,400 TBW endurance with 5-year warranty
- Micron 96L TLC NAND with strong sustained writes
- SK Hynix DDR4 DRAM cache
- Solid competitor to Samsung 980 Pro at lower price
**Cons:**

- Double-sided PCB may not fit some thin laptops
- Warranty drops to 1 year without registration
- No included heatsink (optional variant available)
- No hardware AES encryption
- Phison E18 can run warm under sustained load


## Verdict

The Sabrent Rocket 4 Plus 2 TB is a top-tier PCIe 4.0 drive that belongs in any conversation about the best consumer NVMe SSDs. Its 7,000 MB/s writes and 1 million random write IOPS are enthusiast-grade numbers, and the 1,400 TBW endurance rating provides long-term confidence. The trade-off against Samsung and WD alternatives is mostly brand preference and warranty registration hassle — performance is functionally identical. For a single-drive gaming and productivity build where you want capacity, speed, and reliability in one package, the Rocket 4 Plus 2 TB is an easy recommendation.

## Frequently Asked Questions

### Is the Sabrent Rocket 4 Plus 2TB good for gaming?

Exceptional. The 7,100 MB/s read speed and 650K random read IOPS mean game loads are as fast as the PCIe 4.0 interface allows. At 2 TB, you can store 15–20 large AAA titles alongside the OS and applications. The drive handles DirectStorage workloads without issue, and its write performance ensures game installations and updates complete quickly. There is no practical gaming scenario where this drive is the bottleneck.

### Is the Sabrent Rocket 4 Plus 2TB compatible with the PS5?

Yes, it exceeds Sony's requirements. The PS5 recommends PCIe 4.0 NVMe drives with at least 5,500 MB/s reads, and the Rocket 4 Plus delivers 7,100 MB/s. The bare drive (without optional heatsink) fits within Sony's 11.25 mm total height limit. If you purchase the heatsink variant, verify the combined height meets the PS5 specification. As a PS5 expansion drive at 2 TB, you can store 12–15 large games and load them at full speed.

### What is the TBW endurance of the Sabrent Rocket 4 Plus 2TB?

The 2 TB model is rated for 1,400 TBW (terabytes written), covered by a five-year warranty with registration. At 1,400 TBW, that equals roughly 766 GB of writes per day for five years. A typical gaming desktop writes 30–60 GB/day, meaning the endurance will outlast the warranty by a wide margin. Even a professional user writing 500 GB/day would take over seven years to exhaust the rated endurance.

### Does the Sabrent Rocket 4 Plus 2TB work in a laptop?

Most laptops with an M.2 NVMe slot will accept it, but check two things: first, the Rocket 4 Plus 2 TB uses a double-sided PCB, and some thin laptops only support single-sided M.2 drives. Second, PCIe 4.0 drives generate more heat than PCIe 3.0 models; laptops with limited M.2 cooling may see thermal throttling under sustained writes. For thick gaming laptops with M.2 cooling, the drive works great. For ultra-thin ultrabooks, verify clearance and cooling before purchasing.

### How does the Sabrent Rocket 4 Plus 2TB compare to the WD Black SN850X?

Both are top-tier PCIe 4.0 TLC drives with similar headline numbers. The SN850X uses WD's in-house controller while the Rocket 4 Plus uses Phison's E18. In benchmarks, they trade narrow wins depending on the test — the differences are within margin of error for gaming and desktop use. The Sabrent typically costs less. The WD has a standard five-year warranty without registration requirements. Both are excellent choices; the decision often comes down to price and availability.

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

Yes, particularly at 2 TB. The 7,000 MB/s write speed handles multi-stream 4K and 8K footage imports, and the TLC NAND sustains 1,200–1,800 MB/s even after the SLC cache fills — enough for most professional video workflows. The 2 TB capacity provides room for OS, applications, and active project files. For heavy scratch-disk use with constant writes, the 1,400 TBW endurance ensures the drive can handle the workload over the warranty period without concern.
