What this page is—and isn’t
This is not a TWW hands-on review. TWW has not physically tested or independently benchmarked this product. This page organizes the manufacturer’s specifications, practical buying considerations and links to published external testing where available.
Any performance or usability conclusions attributed to an outside publication remain that publication’s findings. They are not presented as TWW measurements.

What independent testing reports
HotHardware tested the 4TB model and found it strong and well-rounded for a PCIe 5.0 drive, with first-place results in several storage traces and relatively cool, low-power operation. TechRadar’s 4TB review praised sequential write speed but judged the drive expensive and aimed at professionals rather than typical gamers. Those are the outlets’ findings on their own test systems, not TWW measurements.

Configuration note: The reviewed samples were the 4TB model without a heatsink; the heatsink version and other capacities have different ratings and prices.
Potential strengths
- PCIe 5.0 interface with very high manufacturer-rated sequential speeds and a 4TB capacity option.
- HotHardware described the drive as relatively cool-running and low-power for a Gen 5 SSD, and noted that it led its game-storage trace tests.
- TechRadar highlighted sequential write speed as a standout in its testing.
Limitations and buying cautions
- TechRadar’s review measured sequential reads below the box rating at first and later reported reaching the rated figure after retesting on other hardware, so results depend on the test platform.
- Both reviewers consider it a premium-priced drive; TechRadar did not recommend it for most general or gaming users.
- It needs a PCIe 5.0 M.2 slot to reach its rated speeds, and consoles or PCIe 4.0 systems cannot use the extra bandwidth.
Who should consider it?
- Workstations and creators moving very large files
- New PCIe 5.0 builds where the budget allows a premium drive
- Buyers comparing it with the PCIe 4.0 990 PRO on price and real workload benefit
