Sabrent Rocket 4 Plus NVMe 4.0 Gen4 PCIe M.2 1TB SSD Review

Storage/SSD by stefan @ 2022-10-25

The Rocket 4 Plus 1TB has performed as expected given the fact that we are dealing with half of the NAND ICs we have had with the 2TB SKU, so implicitly a smaller quantity of pseudo-SLC cache, while the DDR4 cache was clocked a bit lower. Thanks to the use of TLC NAND, the functionality of the drive is very little affected in terms of performance when having it over 50% filled, but when writing very large quantities of data to it at once, it tends to overheat and throttle.

Product Features, Specifications

Product Features:

 

PCIe 4.0 x4 interface, NVMe 1.3 compliant. APST/ASPM/L1.2 support.

Supports SMART and TRIM functions. Works in an enclosure.

Wide flash compatibility. Uses TLC with DRAM.

Advanced endurance features for a long drive lifespan.

Upgradeable firmware and software support.

4.0-capable motherboard and M.2 heatsink are recommended, but the drive is backward compatible with PCIe 3.0 and 2.0 M.2 sockets.
