Sabrent has a hot seller on its hands right now, and for good reason. The company’s Rocket NVMe 4.0 is cooked up with the same ingredients as the other Gen4 SSDs on the market so far. This means it's packing Kioxia’s latest 3D TLC NAND and is powered by none other than Phison’s PS5016-E16 NVME SSD controller. And, while fairly expensive per GB, Sabrent’s Rocket NVMe 4.0 is priced it well under most high-end competitors, making it one of the best bang-for-your-SSD -buck Gen4 drives yet.
Just note that Sabrent’s warranty policy will only cover the Rocket NVMe 4.0 for up to 1 year if you do not register the SSD within 90 days of purchase. But, if you do, you will receive a longer 5-year warranty instead. That's a small price to pay for a lower price on checkout.

While you have to manually register your Sabrent’s Rocket NVMe 4.0 for its full warranty, you shouldn’t ever have to worry about the device’s endurance. With class-leading endurance ratings, our sample is covered to withstand up to 3,600TB of writes within the warranty period.
It comes in an M.2 2280 form factor and is available in three capacities: 500GB, 1TB, and 2TB. In terms of price, the drive is hard to beat within its niche; it undercuts most other Gen4 SSDs out there. The 1TB and 2TB capacities are rated to hit sequential speeds of up to 5/4.4 GBps and up to 750,000 IOPS, and the smaller 500GB model’s write speed peaks at 2.5 GBps, along with lower peak random performance.
Software and Accessories
Sabrent’s Rocket NVMe 4.0 comes supported by a few pieces of software. You get a free OEM copy of Acronis True Image. If you have any issues cloning due to the device's sector size, there is Sabrent’s Sector Size Converter (SSC) which will allow you to change between 4K and 512e sector sizes for compatibility in that case. Additionally, Sabrent provides a Control Panel application, an SSD Toolbox which you can use to monitor the device and upgrade the firmware if an update is ever released.
A Closer Look
We have to give kudos to Sabrent on the black PCB and very attractive label design. The copper label looks nice and helps to aid in cooling, but on our 2TB sample, it may not be enough to prevent throttling under heavy loads. We will explore this more later on.
At the heart of the SSD is the Phison PS5016-E16 PCIe 4.0 x4 NVMe 1.3 SSD controller. Built on a 28nm process node and featuring dual Cortex R5 CPU cores with dual co-processors (dubbed CoXProcessor 2.0), the overall design is similar to the Phison’s E12. The main difference between the two is not only the PCIe Gen4 PHY but additionally, it boasts Phison’s updated 4th Gen LDPC ECC engine. It utilizes a DRAM caching architecture to maintain strong performance under heavy workloads. Our 2TB sample features two 1GB SK Hynix chips for the task of FTL table mapping.
It also supports thermal monitoring, TRIM, and the Format NVMe command to securely wipe data. Plus, it has end-to-end data protection to keep data safe and power management support for better efficiency.
Also, the device's Kioxia’s BiCS4 96L TLC, which means our Rocket NVMe 4.0 sample is utilizing thirty-two 512Gbit NAND dies spread out into the four NAND packages on the PCB. And the drive has 9% of the NAND set as over-provisioning space to optimize garbage collection.
