# Sabrent Rocket 4 Plus-G 2TB — PCIe 4.0 NVMe SSD Review (2026)

The Sabrent Rocket 4 Plus-G 2 TB is a high-endurance Phison E18 PCIe 4.0 drive that pairs the proven Gen4 controller platform with an unusually generous TBW rating, positioning it for buyers who write more than the typical consumer.

Quick answer: The Rocket 4 Plus-G 2 TB is a Phison E18 drive with an endurance rating that belongs in a different conversation. Its storage performance is identical to every other E18 flagship, but the 5,100 TBW figure — if accurate — puts it in a class of one among consumer PCIe 4.0 drives. For content creators, data scientists, and anyone whose SSD writes are measured in hundreds of gigabytes per day, the Plus-G's endurance premium is a genuine differentiator that may justify its price. For everyone else — gamers, office users, general-purpose desktop builders — the standard Rocket 4 Plus or any competing E18 drive will deliver identical daily performance with an endurance budget that is already functionally unlimited at consumer write rates.

## Performance

Sabrent rates the 2 TB Rocket 4 Plus-G at 7,400 MB/s sequential reads and 7,000 MB/s sequential writes with 1,000,000 IOPS random read and write — numbers that place it at the PCIe 4.0 x4 interface ceiling and are shared across all high-end E18 implementations. The Phison E18's performance is well-characterised by now: peak throughput arrives within 1–2% of rated figures in independent benchmarks, and the large pseudo-SLC cache on a 2 TB drive absorbs roughly 200–300 GB of burst writes before transitioning to native TLC speeds around 1,200–1,400 MB/s.

For gaming and general desktop use, the Rocket 4 Plus-G is indistinguishable from any other E18 drive — and, for that matter, from any PCIe 4.0 flagship. The real-world scenarios that differentiate the Plus-G are sustained write-heavy workloads: 8K video ingest, large database rebuilds, multi-terabyte file transfers, and any workflow where the drive spends significant time writing at full speed. In these scenarios, the Plus-G's endurance headroom means the drive can sustain high write throughput for years longer than a standard E18 drive before approaching its TBW ceiling. For video editors and data analysts who wear out consumer SSDs within their warranty period, the Plus-G's endurance premium may translate to real cost savings over time.

## Endurance, TBW & Warranty

Sabrent covers the Rocket 4 Plus-G 2 TB with a five-year warranty (registration required for full coverage), bounded by an extraordinary 5,100 TBW endurance rating. At 100 GB/day — a heavy content-creation workload — this endurance budget lasts roughly 140 years. For context, the standard Rocket 4 Plus 2 TB carries 1,400 TBW, meaning the Plus-G offers roughly 3.6 times the write endurance on the same controller and NAND platform. The TBW figure is high enough that buyers should verify it against Sabrent's official product page at time of purchase, as endurance ratings at this level are unusual for consumer SSDs and may reflect a specific production batch or warranty program. Sabrent's RMA process is handled through their support portal with shipping labels provided in supported regions.

## Pros and Cons

**Pros:**

- 7,400 MB/s reads — saturating the PCIe 4.0 x4 interface
- 5,100 TBW endurance — roughly 3.6x the standard E18 2 TB rating
- Phison E18 with Micron TLC — mature, proven, high-performance platform
- DDR4 DRAM cache — full FTL in dedicated memory, no HMB compromises
- 5-year warranty with product registration from Sabrent
**Cons:**

- Performance identical to cheaper E18 alternatives — premium is purely endurance
- Sabrent RMA infrastructure is smaller than Samsung or WD equivalents
- Drive runs warm under sustained load — heatsink recommended for desktop use
- Double-sided PCB on 2 TB — may not fit all thin laptops


## Verdict

The Rocket 4 Plus-G 2 TB is a Phison E18 drive with an endurance rating that belongs in a different conversation. Its storage performance is identical to every other E18 flagship, but the 5,100 TBW figure — if accurate — puts it in a class of one among consumer PCIe 4.0 drives. For content creators, data scientists, and anyone whose SSD writes are measured in hundreds of gigabytes per day, the Plus-G's endurance premium is a genuine differentiator that may justify its price. For everyone else — gamers, office users, general-purpose desktop builders — the standard Rocket 4 Plus or any competing E18 drive will deliver identical daily performance with an endurance budget that is already functionally unlimited at consumer write rates.

## Frequently Asked Questions

### Is the Sabrent Rocket 4 Plus-G good for gaming?

The Rocket 4 Plus-G 2 TB is an excellent gaming drive — its 7,400 MB/s reads and DRAM-equipped E18 controller deliver load times that are indistinguishable from any other PCIe 4.0 flagship. The 5,100 TBW endurance rating, while impressive, is irrelevant for gaming: game installs are write-once-read-many operations, and a typical gamer writes far less than 20 GB/day. The 2 TB capacity holds a substantial game library, and the drive will never be a bottleneck in any gaming scenario. If gaming is your primary or only workload, the standard Rocket 4 Plus or a competing E18 drive will deliver identical performance at a potentially lower price — the Plus-G's endurance premium goes unused in a gaming PC.

### Does the Rocket 4 Plus-G have a DRAM cache?

Yes, the Rocket 4 Plus-G includes dedicated DDR4 DRAM as required by the Phison E18 controller. The E18 cannot operate without DRAM — unlike DRAM-less controllers that use HMB to borrow system RAM, the E18 requires its own memory for the flash translation layer mapping tables. The DRAM cache provides lower and more consistent random I/O latency compared to HMB-based drives, and it eliminates the system RAM overhead that HMB imposes. For a drive positioned as a high-endurance workstation SSD, the DRAM is an essential feature for sustained mixed-I/O performance.

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

The Rocket 4 Plus-G 2 TB is rated for 5,100 TBW according to the database specification — an extraordinary figure for a consumer NVMe SSD. At 2,550 TBW per terabyte, this is roughly 3.6 times the endurance of the standard Rocket 4 Plus (1,400 TBW) and approaches enterprise U.2 drive territory. For a content creator writing 200 GB/day, this endurance budget lasts approximately 70 years. The TBW rating is high enough that buyers should verify it against Sabrent's current product documentation, as endurance numbers at this level are unusual for consumer Phison E18 drives and may represent a specific SKU or warranty promotion. If accurate, the Plus-G is one of the highest-endurance consumer PCIe 4.0 drives on the market.

### Is the Rocket 4 Plus-G compatible with the PS5?

The Rocket 4 Plus-G meets all of Sony's PS5 expansion requirements on paper: PCIe 4.0 x4 NVMe M.2 2280, 7,400 MB/s sequential reads (well above the 5,500 MB/s minimum), and performance suitable for PS5-native titles. However, the drive uses a double-sided PCB for the 2 TB capacity and ships without a factory heatsink. Sony requires an M.2 heatsink no larger than 110 x 25 x 11.25 mm, and the double-sided PCB may create clearance issues in the PS5's expansion bay depending on the specific heatsink used. A low-profile third-party heatsink designed for double-sided SSDs and PS5 use is recommended if installing the Plus-G in a console.

### Who should buy the Rocket 4 Plus-G over the standard Rocket 4 Plus?

The Plus-G is specifically for users who write enough data to approach or exceed the standard Rocket 4 Plus's 1,400 TBW endurance rating within their ownership period. This means content creators ingesting 100+ GB of video footage daily, data scientists running write-heavy ETL pipelines, or anyone who has previously worn out a consumer SSD before its warranty expired. For everyone else — gamers, office users, developers compiling code, general desktop users — the standard Rocket 4 Plus's 1,400 TBW is already a multi-century endurance budget at typical write rates, and the Plus-G's endurance premium adds cost without practical benefit.
