The Sabrent Rocket Q4 is a PCI-Express 4.0 M.2 NVMe SSD that uses QLC NAND flash paired with a Phison E16 controller. Performance, especially in synthetic tests is good, and the super-large SLC cache is able to soak up even the largest bursts of write activity. A very decent heatsink is included, too.
