This article covers SABRENT Rocket 4 2TB NVMe SSD PCIe Gen4 M.2 2280 内蔵ソリッドステートドライブ 最大7.

Overview

The SABRENT Rocket 4 2TB (model SB-RKT4L-2TB) is an internal NVMe M.2 2280 SSD designed for PCI Express 4.0 x4 interfaces. It delivers sequential read speeds up to 7,450 MB/s and write speeds up to 6,400 MB/s, making it an excellent choice for high-performance gaming PCs and creative workstations. The drive utilizes TLC NAND flash (Kioxia 162-layer) and employs Host Memory Buffer (HMB) technology to compensate for the lack of a dedicated DRAM cache. Its single-sided M.2 2280 form factor ensures compatibility with thin laptops and compact builds. Positioned in the upper-mid range market, this SSD competes with top Gen4 drives like the Samsung 980 Pro and WD Black SN850X. With random read IOPS of 1,000,000 and random write IOPS of 950,000, it provides snappy OS boot times and fast application loading. It is also officially supported for PlayStation 5 storage expansion, making it a versatile upgrade for both PC and console gamers.

Compatibility Guide

The SABRENT Rocket 4 2TB features a PCIe 4.0 x4 interface and is compatible with any M.2 slot (Key M) on desktop motherboards, laptops, and the PS5 console. It is backward compatible with PCIe 3.0, but speeds will be limited to approximately 3,500 MB/s. To achieve full performance, a motherboard with PCIe 4.0 support is required. Physical dimensions are standard M.2 2280 with a single-sided layout, so it fits easily in most systems without clearance issues. However, some slim laptops may require checking the thickness of thermal pads or mounting holes. For PS5 installation, a heatsink is not mandatory but recommended for sustained workloads; the drive itself runs relatively cool.

Product Info

The SABRENT Rocket 4 2TB was released in 2024 as a high-performance PCIe 4.0 NVMe SSD. It offers 2TB of storage with sequential reads up to 7,450 MB/s and writes up to 6,400 MB/s. The NAND is Kioxia 162-layer TLC, and the controller is a proven Phison PS5018-E18 (based on industry knowledge). It uses HMB instead of a dedicated DRAM cache, which keeps costs lower while still delivering excellent random performance. Market positioning is upper-mid tier, competing directly with drives like the Samsung 980 Pro and WD Black SN850X. The TBW rating is approximately 2,400 TB for the 2TB model, providing a calculated endurance of about 6.6 years under daily 1TB writes. The manufacturer offers a 5-year warranty (registration required). It is also officially certified for PS5 internal storage expansion.

Best Use Cases

Gaming: Ideal for loading large game files quickly. Titles like Call of Duty: Modern Warfare II or Starfield benefit from reduced load times and smoother texture streaming. PS5 users can install it as expanded internal storage with full console support. Creative Work: Video editors working with 4K/8K footage and photographers handling RAW files will appreciate the high sequential speeds. Large project files open and save rapidly, improving workflow efficiency. * PC Enthusiasts: Builders seeking a high-performance OS drive for a compact or high-end system. Pairing this SSD with a PCIe 4.0 motherboard maximizes system responsiveness for everyday tasks and multitasking.

Things to Consider

Because this SSD is DRAM-less, it may experience performance drops during heavy sustained writes or multi-threaded workloads compared to models with dedicated DRAM (e.g., Samsung 990 Pro). It is not ideal for server or NAS applications with constant write pressure. Users running older PCIe 3.0 systems will see only half the speed, so a platform upgrade is recommended to unlock the drive's full potential. Within Sabrent’s lineup, the Rocket 4 Plus offers higher sequential speeds (up to 7,100 MB/s) and includes DRAM cache, making it a better choice for extreme workloads. The Rocket 4 2TB is priced around ¥70,000 in Japan, which is premium but justified by its performance and PS5 compatibility. Always verify that your motherboard’s M.2 slot supports PCIe 4.0 before purchase.
