We are testing Rocket NANO V2 4TB in this content. Earlier we tested the 2TB variant of this series. This drive features an on-board UFD controller which is a unique feature as the majority of portable drives don’t have such a controller on-board. This drive uses the USB 3.2 Gen2x2 interface which has a theoretical bandwidth of 20Gbps. This drive is rated for up to 1500MB/s in sequential read/write thanks to the NVMe SSD being housed inside the aluminum shell.

I am showing the drive after removing the sleeve. Sabrent uses space-grade aluminum alloy via CNC machining for the housing of the drive. This material is said to have better heat transfer and is more durable. The Sabrent branding is visible on the top. There is a white color LED indicator on the bottom right to show the drive activity. The dimension of the unit is 2.85×1.28×0.57 inches (LxWxH). The weight of the unit is 1.76oz.

The Rocket NANO V2 series is available in three sizes:

  • 1TB
  • 2TB
  • 4TB

Size Comparison

The above picture shows the size comparison of the NANO V2 against the credit card and a coin. We appreciate the small footprint of the Rocket NANO V2 making it convenient to carry around.

Sabrent Rocket NANO V2 4TB Drive 5

The drive uses a USB Type-C interface. This drive is using USB 3.2 Gen 2×2 protocol over the USB Type C interface. The theoretical throughput for this protocol is 20Gbps. This is double the bandwidth of the Rokcet NANO which is 10Gbps. The drive is listed for up to 1500MB/s read and write sequentially. This is not all as this drive is said to sustain 800MB/s speed under heavy loads. The drive is said to have a sustained performance capable of smooth 8K video recording.

Sabrent Rocket NANO V2 4TB Drive 6

There is a Sabrent branding on the opposite end of the drive.

Looking at the drive from the backside, there is a label showing the serial number of the drive along with its model number. This drive is designed in the USA and manufactured in Taiwan.

Sabrent Rocket NANO V2 4TB Cables

Sabrent has provided two cables in the box. One is the USB Type-C to Type-C cable and the other is a USB Type-C to Type-A cable. Using the later cable will make the drive operate at USB 3.2 10Gbps speed.

This would allow the user to connect the drive as per the available USB port in the system though using USB Type-A would reduce the transfer rate. The length of these cables particularly the Type-C to Type-C cable is short. This would be difficult if we were connecting the drive directly with the PC. The Sabrent Rocket Nano series drives are compatible with Microsoft Windows and MAC OS. They are plug-and-play and don’t need any software and are backward compatible with the USB protocols.

What makes this drive special?

We have mentioned above that this drive has a native UFD controller. What does it mean? So far, portable drives boasting high speeds have been using bridged chip design. This means they are using two controllers to connect the SSD with the interface like USB 3.0, USB 3.2, etc. The main issue with this design is the high-power draw which results in more heat and lack of good enough backward compatibility with multiple hosts.

No more! Sabrent has ditched that design and has come up with the on-board USB controller to interface directly with the host and the target. This not only eliminates the bridging but improves the power efficiency which in turn reduces the heat generation from the controller. There is another key benefit which is extreme backward compatibility say up to USB 1.1.

Sabrent has employed a Phison PS2251-18 USB 3.2 Gen2x2 controller on this drive which eliminates the bridging and provides a direct connection which is faster.


As we can see using this controller, the drive is now compatible with the USB 1.1 interface. Sabrent uses SK Hynix 128L TLC chips (NAND) on the NVMe SSD. This provides a powerful combination of the NAND and controller to deliver fast and smooth data transfer rate. The controller also has a thermal sensor which is a plus to the design.

Sabrent has provided the power draw as follows:

Read 500mA
Write 550mA
Idle 150mA
Suspended 1.7mA

This is a game changer for portable drives as this drive uses almost the best power efficiency possible out there.


The following configuration is used:

  • AMD Ryzen 9 7950X
  • Kingston Fury Renegade 32GB DDR5 kit @ 6400MT/s CAS32
  • ARCTIC Liquid Freezer II – 420 AIO
  • XPG S50 Lite 1TB NVMe SSD [OS Drive]

Next, we copied the same compressed file from one folder to another on the same drive. The transfer rate 405MB/s and it almost took 4 minutes to complete the operation.

Sabrent Rocket NANO V2 4TB Disk Bench Copy Dir

Next, we copied a folder of 210GB size containing multiple compressed files, sub-folders, and mixed other files. The transfer rate was 338MB/s with a time of 11 minutes. The lowest speed that we saw was 87MB/s which is subject to the type of folder/file being copied because the drive was not throttling.

Gaming Load Time

We have also calculated the game’s loading time using the Final Fantasy XIV : Shadowbringers Benchmark using High settings. This is meant for users who would like to store a few games on the external fast storage.

Sabrent Rocket NANO V2 4TB Final Fantasy XIV Shadowbringers Benchmark

We have a load time of 13.05 secs.


We saw a maximum temperature of 63°C at an ambient temperature of 25°C on the Rocket NANO V2 4TB.


We have tested the Sabrent Rocket NANO V2 4TB drive in this article. This series of drives is available in 1TB, 2TB, and 4TB sizes. These drives have the same dimensions as we saw on Rocket NANO first-generation drives. Given their small footprint, these are convenient to carry around despite having large capacities.

This is an enthusiast-grade fast-storage solution from the manufacturer based on USB Gen 3.2 Gen 2×2 on a Type-C interface. These drives are rated for up to 1500MB/s read and write in sequential. This is not all as these are said to have sustained 800MB/s rate under heavy load and capable of smooth 8K video recording.

The housing of these drives is made of high-grade aerospace aluminum alloy which is CNC machined for perfection. This housing not only adds rigidity to the drive but also transfers the heat from the drive to protect it from overheating. Sabrent has provided 2x cables with the drive. One is the USB Type-C to Type-C cable whereas the second one is the USB Type-A to Type-C cable. The drive supports Advanced Wear Leveling and Bad Block Management. The drive comes with a silicon sleeve around it which is removable. This sleeve provides protection in case of an accidental fall.

This drive has our high praise as it houses an on-board USB3.2 Gen2x2 controller which eliminates the bridging design. The control is Phison PS2251-18. This controller supports up to 4TB capacity and supports TLC as well as QLC NAND types. Speaking of NAND, the V2 houses SK Hynix 128L TLC chips. The controller is power efficient.

During our test, we saw the drive confirming the rated 1500MB/s sequential read and write speeds in the synthetic benchmarks with a better 4k performance. We have observed that these drives work a bit slow on the AMD platform compared to the Intel platform. This level of performance is very good as we are getting much faster speeds with high capacities. The real-world performance is obviously what matters and our testing has shown that this drive is capable of handling data transfer at an average of 300 to 400MB/s depending on the data type.

The Rocket NANO V2 4TB drive is listed at USD349.99 at the time of the review. Sabrent is offering a one-year warranty that could be extended to 3 years upon registration of the drive on their website. Once again, the NANO word serves the purpose. With capacity as high as 4TB in such a small footprint and blazing fast speeds, the NANO V2 series of drives come recommended by us.

Thanks to Sabrent for the provision of the test unit.
