Sabrent Rocket 4 Plus-G NVMe Gen4 2280 2TB SSD Review

Storage/SSD by stefan @ 2023-03-12

The new Rocket 4 Plus-G 2TB performed admirably in our tests, trading punches with the non-G variant while kept blank but outperforming it when filled more than 50%. We did also note a sustained write rate much higher than the drives we have tested before, being able to finish writing over 1.1TB with about 2.7GB/s, which is quite impressive! The offered heatsink really does its job and prevents throttling during intense workloads, for the Rocket 4 Plus-G to always perform at its top.

A Closer Look Part II

PCIe 4.0 SSDs are known to run hot and right from the first page of the manual we will be reminded to use an additional heatsink:

The Rocket 4 Plus-G drive looks really cool with the pre-installed copper foil which acts as a heatspreader. The iridescent purple does look different depending on how the light is oriented:

On the back, we will note a regular sticker sporting the same SSD details, but also a QR code:

Here is how the copper foil does look after it has been removed from the drive:

On this drive, the PCB is quite crowded, including the central controller along with the DRAM for caching purposes, but also four NAND ICs:

The Phison PS5018-E18 Gen4 NVMe 8-channel controller was build on TSMC’s 12nm process and supports up to 8TB configurations, with a NAND transfer speed of 1600MT/s per channel:

The DRAM cache is a H5AN8G6NCJ DDR4 part from SK hynix, with a capacity of 1GB:

The Micron’s 176-layer TLC ICs can be found here as well, with the IA7BG94AYA part number, same as on the regular Rocket 4 Plus:
