The 4 TB SanDisk Extreme PRO Portable SSD uses USB4 to deliver near-internal SSD performance with up to 3800 MB/s reads, while offering rugged IP65 protection and hardware encryption. It shines on Thunderbolt-4 hosts but can fall back to slower speeds on older machines, and its larger size makes it less pocket-friendly.

Professional reviewers such as ServeTheHome commend the Extreme PRO for its top-tier 2000 MB/s throughput and rugged build, noting it excels in high-resolution video workflows but caution about past firmware reliability and its comparatively larger size.
Everyday users overwhelmingly praise the drive's speed, durability, and ease of use for on-location media work, while recurring complaints focus on data loss when unmounted incorrectly, reduced speeds on Apple devices, and iPhone incompatibility.
“Fast media transfer, durable and small... perfect for run-and-gun filming!”
“Backed up all my precious photos and videos... highly recommend.”
“Our video editors like this product a lot - best for caching.”
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.
