WD P40 Game Drive 1TB
Score: 65/100
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 WD_BLACK P40 1TB Game Drive delivers flagship-class 2,000 MB/s speeds and a rugged aluminum design with RGB flair, targeting gamers and creators who need fast transfers, but it can overheat and lacks encryption.

Professional reviewers praise the P40 for its near-flagship sequential speeds, solid aluminum construction, and superior random write performance, while noting thermal throttling and the lack of hardware encryption.
Everyday users love the lightning-fast transfers, rugged feel, and eye-catching RGB, often highlighting how quickly large game libraries move and the drive survives drops, but recurring complaints focus on heat buildup and Windows-only RGB control.

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.
