Professional reviewers praise the Extreme PRO for its 2000 MB/s speeds, rugged build, and long warranty, but warn about firmware-related reliability problems and limited compatibility with Apple devices.
Users love the rapid transfers and ruggedness, yet many report sudden drive failures after extended use and frustration with firmware support.
“Transfers 4K video files in seconds”
“Love the included cables - no need to carry adapters”
“Drive suddenly became unreadable after 18 months - lost all my project files”
Professional reviewers commend the Extreme PRO USB4 SSD for its blazing peak speeds and rugged build, but repeatedly warn that real-world performance hinges on a fully compatible 40 Gbps host. PCWorld and The SSD Review note that without BIOS or firmware updates the drive often falls back to slower USB 3.x rates, and some USB4 implementations cap at 32 Gbps, keeping it slightly behind rivals like the Samsung X5. Nonetheless, on Thunderbolt-4 Macs the drive consistently hits its advertised 3800 MB/s reads.
Everyday users, especially video editors and photographers, praise the drive's speed, plug-and-play ease, and durable design for on-location work. The average rating hovers around 4.5 / 5, though recurring complaints focus on initial connection hiccups, the larger form factor, and occasional speed throttling after the cache is exhausted.
