Sabrent Rocket 4 Plus Gen 4 NVMe SSD Review (4TB) – Performance, Capacity and Warranty

Back in December, we posted our review on the one and two terabyte versions of the newest Sabrent Rocket 4 Plus PCIe 4.0 NVMe M.2 SSD, both of which received our Editor’s Choice as being one of the best available in the industry.  Breaching 7GB/s read speeds and coming very close to that with write performance is not an easy task. Add to that great pricing and a 5-year warranty on registration and well, Sabrent is doing something right.  Today, they have gone a step further and added capacity to the mix as we have the 4TB version of the Rocket 4 Plus on our Test Bench.

As a bit of a spoiler, the 4TB version of the Rocket 4 Plus did up the performance of its brethren, but more importantly, it is nice to see one of the top SSDs on the market available in a 4 TB capacity.  Nobody else has done this and, should you see a 4TB Gen 4 SSD elsewhere, you can bet it will be QLC NAND flash memory rather than the upper tier Micron 96-Layer 3D TLC NAND flash memory…as this SSD is.

As is standard with Sabrent, they package their SSDs to reflect the quality of what you are getting.  The outside cardboard casing is of an attractive black and gold design and measures only 4″ x 2 7/8″ x 1/2″.  Doesn’t it seem rather odd that other manufacturers ship SSDs that measure just over 3″ long by 7/8″ wide and weighing less than 10gm in packaging reflective of that of a keyboard?

The Sabrent Rocket 4 Plus NVMe M.2 SSD sits comfortably inside a gold aluminum shell type case with its Installation Guide.  It is a two sided SSD, as it should be given respect to its capacity, with a gold metal heatsink and inclusive branding on one side and white label on the other.

The Sabrent Rocket 4 Plus SSD is a PCIe 4.0 (Gen 4) M.2 SSD of the 2280 (80mm) form factor and uses the latest NVMe 1.4 protocol. It is available in 1,2 and 4TB capacities and performance for the 4TB version is listed at 7100MB/s read and 6600MB/s write.

Looking at the Rocket 4 Plus black PCB from left to right, we have the Phison PS5018-E18 controller, SKHynix DDR4 DRAM along with 4 pieces of Micron 96-layer 3D TLC NAND flash memory.

We have another 4 pieces of NAND flash and another 2GB DRAM ic on the back for a total of 8 packages of NAND with a 512GB RAW value per and 4GB DDR4 DRAM buffer. This is definitely one of the largest DRAM buffer sizes we have seen to date.

Checking Amazon, we see that the Sabrent Rocket 4 Plus Gen 4 NVMe M.2 SSD is available for a price of $999.99. This also includes access to Sabrent’s Rocket Control Panel and Acronis True Image cloning software.  Something we were totally unaware of until this report is that, depending on whether you are checking a PCIe 3 SSD, PCIe 4 Q or PCIe 4 Rocket, the color pattern of the software changes and includes different features as shown here where we have just tested the Rocket 4 Plus:
