Earlier this week we took a look at the Sabrent Rocket NVMe SSD series that uses TLC (Triple-Level Cell) NAND Flash memory that stores three bits of data per cell. Today, we’ll be taking a look at the Sabrent Rocket Q NVMe SSD series that uses QLC (Quadruple-Level Cell) NAND Flash memory that stores four bits of data per cell. QLC (Quadruple Level Cell) stores more bits per cell than its predecessors, enabling larger drive capacities at more affordable price points. The smallest Sabrent Rocket Q NVMe PCIe 3.0 x4 M.2 2280 SSD is 1TB in capacity and can be bought for $110. The Rocket Q is also available in 2TB or 4TB capacity models if you have larger storage needs. The endurance on QLC drives is not as high as you’ll find on TLC drives, but the performance numbers look pretty good as the 4TB model can reach speeds of up to 3,400 MB/s read and 3,000 MB/s write.
