Packaging and Unboxing


The Sabrent Rocket 4 Plus G series of SSDs are available in 1TB/2TB/4TB capacities. There is no 8TB variant yet. This is understandable from the costing point of view. The NAND Flash, the controller, and the dedicated firmware would add more to the equation here. These SSDs are using 3D TLC NAND Flash.

This SSD has a form factor of 2280. It is an M Key SSD compatible with M.2 slots on modern motherboards. It is also compatible with PCIe Gen 3 with reduced speeds, though I don’t see a reason to buy expensive storage for use on a step-down interface.

The SSD’s top features a slim copper cover, distinguishing it from the 1TB variant with a vibrant, reflective aesthetic. While visually appealing, it won’t boost data transfer speeds—similar to how more RGB won’t enhance FPS.

The Sabrent branding, “2TB,” and “Rocket 4 Plus-G” adorn the SSD. Developed in the USA, it’s an Advanced Gaming PCIe 4 M.2 SSD that works seamlessly with Windows 10 and 11, relying on native NVMe drivers. Though dimensions aren’t officially provided, it aligns with the Rocket 4 Plus non-G 2TB variant at 3.15×0.86×0.11 inches (LxWxH).

Flipping to the backside, a prominent black sticker label on this SSD displays crucial details: Serial Number, Part Number, Drive Capacity, Drive Name, Scan Label, and Conformance Logos. Strangely, Sabrent’s website lacks in-depth information about these drives missing performance metrics for this series.

My hunch is that this SSD, at its core, mirrors the Rocket 4 Plus non-G without the O₂ GO firmware. For more insights, I referred to the Rocket 4 Plus 2TB webpage, urging Sabrent to update their site.

If these match the Rocket 4 Plus 2TB, shock resistance stands at 1500G, with an MTBF of 1,600,000 hours. The SSD carries a 2-year warranty, extendable to 5 years with registration, promising a TBW of 1400 TB, translating to a guaranteed 280 TB annually over a 5-year warranty period.

Sabrent touts sequential speeds of up to 7300MB/s in reads and 6900MB/s in writes, yet 4K random read and write speeds remain undisclosed. Drawing a parallel with the Rocket 4 Plus 2TB (Non-G), an estimated 1,000,000 IOPS in Random 4K read and write could be expected.

We are showing a picture from the base where we are trying to show you that both sides of the PCB are populated, meaning this is a dual-sided design.

This SSD seems to have:

  • NVMe M.2 PCIe Gen4 x4 Interface.
  • PCIe 4.0 Compliant / NVMe 1.3 Compliant.
  • Power Management Support for APST / ASPM / L1.2.
  • Supports SMART and TRIM commands.
  • It supports ONFi 2.3, ONFi 3.0, ONFi 3.2, and ONFi 4.0 interfaces.
  • Advanced Wear Leveling, Bad Block Management, Error Correction Code, and Over-Provision.
  • Upgradeable Firmware.

The above picture shows the M.2 port. This connector goes into the M.2 slot of your motherboard. The Sabrent Rocket 4 Plus G 2TB is powered by a Phison E18-41 controller (PS5018-E8-41).

This controller is based on TSMC 12nm process technology that uses a 32-bit ARM Cortex R5 microcontroller in Triple-CPU architecture. It has a support of up to 8 channels. The controller supports Dynamic SLC Cache and 1600MT per channel in DDR4 DRAM.

This SSD is using powerful B47R flash chips from Micron. These 176-layered TLC chips are rated for 1660 MT/s. The B47R has four dies, each having a size or, more appropriately, density of approximately 64 GB. This SSD has two DDR4 DRAM or cache chips from SK Hynix, each with a size of 1GB. These are rated at 3200MT/s with latencies of 22-22-22.
