Introduction

Sabrent is an American hardware manufacturer that was founded in 1998. Their product ranges include external drive enclosures, cables, chargers, card readers, USB hubs, and similar peripherals. In the last few years, they've made a name for themselves in the SSD market by offering highly cost effective solid-state drives with good performance.

They are particularly well-known for offering QLC drives with good performance at very reasonable pricing, like the Sabrent Rocket Q.



Today, we have for review the Sabrent Rocket Q4, which, as the name suggests, uses the PCI-Express 4.0 interface, which doubles the theoretical bandwidth over PCI-Express Gen 3. Under the hood, the Sabrent Rocket Q4 uses a Phison E16 controller, which we've seen on drives like the Gigabyte PCIe 4.0 SSD, Seagate FireCuda 520, and Corsair MP600 Core. The former drives were all based on TLC NAND flash, but the Rocket Q4 uses QLC flash instead. The flash chips are Micron 96-layer QLC, pretty much the market-dominating QLC available at this time. Two DDR4-2666 DRAM chips provide 2 GB of memory for the mapping tables of the SSD.

The Sabrent Rocket Q4 comes in capacities of 1 TB ($150), 2 TB ($300), and 4 TB ($700). Endurance for these models is set to 200 TBW, 400 TBW, and 800 TBW respectively. Sabrent includes a five-year warranty with the Rocket Q4. The big heatsink adds $20 to the price point.
