Transcend ESD410 2TB SSD
Score: 76/100
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 Transcend ESD410C 2TB delivers flagship-class 2000 MB/s speeds while offering military-grade durability, hardware encryption and ProRes video support. It's lightweight and versatile but can run hot and needs the right cable to unlock its full bandwidth.

Professional reviewers rate the ESD410C as a top-tier portable SSD, highlighting its near-maximum USB 3.2 Gen 2x2 throughput, military-grade durability, and high sustained write speeds.
Everyday users rave about the lightning-quick transfers, rugged build and seamless iPhone ProRes recording, though they note heat buildup and occasional cable confusion.
“The drive transfers my 4K footage in seconds and survived a drop from a table.”
“Gets hot after long sessions, but performance is unbeatable.”
“I wish the LED indicator was included for transfer status.”
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.
