With its latest SSD, Sabrent has broken the boundaries of fast flash memory and high capacity, even surpassing well-known figures in the industry.We believe that 8TB of flash storage is niche and extreme for most professional consumers and enthusiasts. We first reviewed Sabrent’s 8TB Rocket XTRM-Q, But now the company is doubling the capacity and pushing capacity to new limits with its 16TB model.
The new version doubles the capacity to 16TB, but due to its larger form factor and power requirements, it is not as portable as the 8TB model. Although the original XTRM-Q included a Rocket Q M.2 NVMe SSD, the new 16TB model has two behind a slightly different Thunderbolt 3 bridge, providing those who need a lot of fast flash memory and potential bus saturation Performance it. However, its cost is high, about $3,000, and it is more of a niche purchase for those who can afford it.

Sabrent’s 16TB XTRM-Q through Thunderbolt 3 provides sequential read performance of up to 1.4 GBps or 2.8 GBps, depending on how you configure your device. It lacks an official sequential write performance rating, but according to our testing, it provides the same performance during a write workload as during a read task. It can be configured in RAID 0, RAID 1, or JBOD to customize the drive for performance, data reliability, or flexibility, respectively.
XTRM-Q is priced at US$2,899.99, which is not cheap and has no warranty. It comes with a three-year warranty, which is short for this capacity and price point product. It is worth noting that the three-year warranty is longer than the one-year warranty of Sabrent’s standard. SSDs also lack durability ratings, like most portable SSDs, but don’t expect Optane-like durability.Each SSD within may be limited to one Similar endurance to Rocket Q Drive under the hood.
Software and accessories
The 16TB Rocket XTRM-Q is equipped with a 28-inch USB-C Thunderbolt 3 cable and a power brick to power the device. The power brick is not optional-without it, the device will not boot. Our samples also come with a breathable silicone sleeve for drop resistance. In addition, the company also provides Sabrent’s RAID assistant software, which can be configured quickly and easily in RAID 0, RAID1, or JBOD settings.
Take a closer look
The 16TB Rocket XTRM-Q measures 115 x 65 x 16 mm and weighs 233 grams. Given its capacity, it is a small and compact storage device.It’s better than LaCie 2big RAID 16TB we reviewed in 2019, But not even twice as big as the portable 8TB Rocket XTRM-Q.
The shell is made of solid aluminum, which feels very good. It also has rubber feet to prevent slipping wherever you place it. There are two power/activity indicators on the left side of the Thunderbolt 3 port, DC-in on the right side, and a power button.
Sabrent’s Rocket XTRM-Q is fully certified by Intel Thunderbolt. Internally, it is supported by the Intel JHL6340 Thunderbolt 3 controller, and each SSD is allocated two PCIe 3.0 channels. These drives support Trim and SMART data reporting, but as an Alpine Ridge-based controller, this drive is only compatible with Thunderbolt 3 and will not work when plugged into a standard USB C port. This is similar to what we see on some Thunderbolt 3 devices powered by Titan Ridge.
In addition, the RAID function is not built-in through the hardware controller; instead, the SSD uses the software RAID function built into Windows or macOS.
As mentioned earlier, XTRM-Q is driven by two 8TB Rocket Q M.2 NVMe SSDs. Each has a Phison E12S NVMe SSD controller and a DDR3L DRAM cache, with eight NAND packages of Micron 1Tb 96L QLC flash memory. In addition, each quad-plane chip provides better interleaving capabilities (thus improving performance) compared to the dual-plane design in competing flash memory. This is especially important considering the generally slow program time of QLC.
The controller runs at 666 MHz, but the interface speed between the flash memory and the controller is slower than the retail Rocket Q we reviewed earlier. The interface speed of these models is not 666 MTps, but 333 MTps to control heat, but fortunately, this is enough to maintain responsiveness for their intended external applications.
