Score: 72/100
SanDisk Extreme PRO 4TB USB4
Score: 92/100Rankings

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.

The Samsung T7 Shield 1TB is a rugged portable SSD with IP65 protection, 3 m drop resistance and AES-256 encryption, delivering up to 1,050 MB/s read speeds. It balances durability and security with solid performance, though it carries a higher price tag and lacks full waterproofing.

Products in the top-left offer the best value (high score, low price).

Professional reviewers commend the T7 Shield for its rugged IP65 construction, solid drop resistance, and reliable AES-256 encryption, noting that its 1,050 MB/s read speed makes it suitable for on-the-go 4K editing. However, they point out that its performance lags behind non-rugged Thunderbolt or USB-3.2 Gen 2x2 drives, and the absence of immersion protection and a fingerprint sensor keep it from being a universal leader.
Everyday users appreciate the drive's durability, fast transfers, and hassle-free plug-and-play experience, often citing reliable backups and smooth media workflows. Recurring complaints focus on the premium price, the feel of the supplied cables, heat buildup during long transfers, and the desire for full waterproof (IP68) protection.

“4.8/5 stars based on over 1,270 reviews”

“The T7 Shield survived a drop from a ladder during a shoot and kept working flawlessly.”

“I wish it had IP68; a sudden rainstorm still left a tiny splash inside.”




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.
