# Sabrent Rocket 4 Plus 1TB — Enthusiast PCIe 4.0 TLC NVMe (2026)

The Sabrent Rocket 4 Plus 1 TB is where this enthusiast TLC lineup hits its stride — 7,100 MB/s reads, 6,600 MB/s writes, and 700 TBW endurance from a Phison E18 and Micron 96L TLC combination.

Quick answer: The Sabrent Rocket 4 Plus 1 TB is a competitive enthusiast PCIe 4.0 drive that trades blows with the Samsung 980 Pro and WD Black SN850X at a lower price point. The Phison E18 and Micron TLC combination delivers 7,100/6,600 MB/s with no significant weaknesses for desktop workloads. The 700 TBW endurance and five-year warranty provide long-term reliability. The main drawback is the registration requirement for the full warranty — forget to register and you are covered for one year instead of five. If you want top-tier PCIe 4.0 TLC performance and are willing to register the product, the Rocket 4 Plus 1 TB is one of the strongest options in its class.

## Performance

At 7,100 MB/s sequential reads and 6,600 MB/s sequential writes, the Rocket 4 Plus 1 TB sits near the practical ceiling of the PCIe 4.0 x4 interface. The 650K random read IOPS and 700K random write IOPS handle anything a desktop workload can throw at them. Independent reviews from Guru3D and CDR Labs confirm that the E18 controller delivers consistent performance across a range of benchmarks, with only minor variation between the Sabrent and other E18-based drives like the Seagate FireCuda 530.

The Micron TLC NAND provides a more forgiving write profile than QLC alternatives. After the pseudo-SLC cache exhausts — which happens after roughly 50–100 GB of sustained writes on the 1 TB model — native TLC speeds sustain around 1,000–1,500 MB/s, which is a far smaller cliff than QLC drives face. For gaming, content creation, and general desktop use, the Rocket 4 Plus 1 TB delivers enthusiast-tier performance without the compromises of budget-oriented drives. Real-world game load benchmarks show the Rocket 4 Plus 1 TB trading narrow wins and losses with the Samsung 980 Pro and WD Black SN850X.

## Endurance, TBW & Warranty

Sabrent rates the Rocket 4 Plus 1 TB at 700 TBW, backed by a five-year warranty that requires product registration within 90 days of purchase. Without registration, the warranty drops to one year. At 700 TBW, you can write approximately 383 GB per day over five years before reaching the rated limit. For a 1 TB drive in a typical enthusiast desktop writing 30–60 GB/day, this provides years of margin. The drive reports health and remaining endurance through standard S.M.A.R.T. attributes accessible via Sabrent's support tools or third-party utilities like CrystalDiskInfo. S.M.A.R.T. health monitoring is supported for tracking endurance consumption over time.

## Pros and Cons

**Pros:**

- 7,100 MB/s reads, 6,600 MB/s writes
- Micron 96L TLC NAND sustains well after cache exhaustion
- Phison E18 12 nm controller with NVMe 1.4
- 700 TBW endurance with 5-year warranty
- SK Hynix DDR4 DRAM cache
- Single-sided PCB fits laptops and desktops
**Cons:**

- Warranty drops to 1 year without product registration
- No included heatsink (optional variant available)
- No hardware AES 256-bit encryption
- Write speeds lower than 2 TB and 4 TB variants


## Verdict

The Sabrent Rocket 4 Plus 1 TB is a competitive enthusiast PCIe 4.0 drive that trades blows with the Samsung 980 Pro and WD Black SN850X at a lower price point. The Phison E18 and Micron TLC combination delivers 7,100/6,600 MB/s with no significant weaknesses for desktop workloads. The 700 TBW endurance and five-year warranty provide long-term reliability. The main drawback is the registration requirement for the full warranty — forget to register and you are covered for one year instead of five.

## Frequently Asked Questions

### Is the Sabrent Rocket 4 Plus 1TB good for gaming?

Excellent. The 7,100 MB/s read speed and 650K random read IOPS handle any gaming workload without bottlenecking. Game load times are on par with the Samsung 980 Pro and WD Black SN850X — the difference between these drives is within measurement noise. The 1 TB capacity fits the OS plus 6–10 large AAA titles, making it a practical single-drive solution for most gaming builds. For larger game libraries, the 2 TB model is worth the upgrade.

### Is the Sabrent Rocket 4 Plus 1TB compatible with the PS5?

Yes, and it exceeds Sony's recommendations. The PS5 requires PCIe 4.0 NVMe M.2 2280 SSDs with at least 5,500 MB/s recommended read speed; the Rocket 4 Plus delivers 7,100 MB/s. The bare drive (without optional heatsink) fits within Sony's 11.25 mm height limit. If you buy the heatsink variant, verify the total height does not exceed the PS5's clearance. Performance in PS5 games is comparable to Sony-approved drives like the Samsung 980 Pro.

### Does the Sabrent Rocket 4 Plus 1TB have DRAM?

Yes. It uses SK Hynix DDR4 DRAM dedicated to the flash translation layer. This is a hardware DRAM cache, not a host memory buffer implementation. The DRAM ensures the controller always has fast access to the logical-to-physical address mapping table, which is critical for maintaining high random I/O performance — especially on a TLC drive where the mapping table is larger than on QLC at the same capacity.

### What is the TBW endurance of the Sabrent Rocket 4 Plus 1TB?

The 1 TB model is rated at 700 TBW (terabytes written), covered by Sabrent's five-year warranty with registration. This equals approximately 383 GB of writes per day over five years. For a gaming and general-use desktop that typically writes 30–60 GB/day, you have roughly 6–12 times the endurance you need. Even a content creator writing 200 GB/day would take nearly ten years to exhaust the warranty-rated endurance.

### How does the Sabrent Rocket 4 Plus compare to the Samsung 980 Pro?

Performance is very close. Both deliver around 7,100 MB/s reads and 6,600–6,900 MB/s writes on the 1 TB capacity. The Samsung uses its in-house Elpis controller and proprietary V-NAND, while the Sabrent uses Phison's E18 and Micron TLC. In practice, the differences are within benchmark margin of error for gaming and desktop use. The Sabrent typically costs less on Amazon, while the Samsung has broader brand recognition and more consistent warranty support. For PS5 use, both are excellent choices.

### Is the Sabrent Rocket 4 Plus 1TB good for video editing?

Yes for 1080p and 4K editing with moderate project sizes. The 6,600 MB/s writes handle multi-stream 4K ProRes and RAW footage imports without issue, and the TLC NAND sustains writes well after the SLC cache fills. For heavy 8K workflows or scratch-disk use with constant large-file writes, the 2 TB model offers better sustained performance and more capacity. The 1 TB works well as a boot drive paired with a separate larger-capacity media drive.
