Score: 71/100
Teamgroup C162 256GB
Score: 65/100Rankings

The Corsair Flash Survivor Stealth 128 GB is a rugged USB-3.0 drive featuring aircraft-grade aluminum housing, 200 m waterproof rating, and 1500 G shock resistance. Its write performance is inconsistent and the long, protruding shape can be cumbersome. Best suited for outdoor workers and travelers needing durable storage.

TeamGroup's C162 256 GB drive combines a rugged zinc-alloy metal body with waterproof, dustproof and shockproof protection, plus a lifetime warranty. Its real-world sequential speeds are modest, falling well short of the advertised 140 MB/s. Ideal for travelers and users prioritizing durability over high performance.

Professional reviewers commend the Corsair Survivor Stealth for its rugged aluminum build, 200 m waterproof rating, and 1500 G shock resistance, noting it as a solid choice for demanding environments. They also acknowledge the USB 3.0 speed boost over older models but caution that real-world write performance can be erratic and that the uncapped, bulky form factor may be inconvenient for some users.
Everyday users love the drive's ability to survive water, drops, and rough handling, often sharing stories of it surviving submersion or being dropped from heights. However, they are repeatedly disappointed by slower-than-expected transfer speeds and the easy-to-lose cap, and many find the long, protruding shape cumbersome for regular laptop use.

“well built, reliable, fast, and reasonably priced”

“sturdy feeling”



Professional reviewers acknowledge the C162's robust metal construction and lifetime warranty, but they criticize its severely limited real-world performance, especially the gap between advertised and measured speeds and the negligible 4K throughput, making it unsuitable for demanding transfer tasks.
Consumer feedback is sparse, but the available data suggests users are likely to be disappointed by the slow actual transfer rates despite the drive's advertised speed claims, while appreciating its compact, rugged design.
