Techkey USB Flash Drive 128GB
Score: 79/100Rankings

The Techkey 128 GB MFi-certified flash drive offers versatile three-in-one connectivity and a rugged metal build, delivering fast USB 3.0 speeds. Its main drawbacks are the mandatory iOS app and the lack of detailed size/weight specs. Ideal for travelers and iOS users who need a durable, cross-platform backup solution.

The Marryler 230 GB USB 2.0 flash drive offers a high-capacity metal body that is waterproof and includes a keychain for easy portability. Its main trade-off is the slow USB 2.0 interface and limited warranty. Best suited for users who need large storage for occasional backups and value rugged, portable design over speed.

“USB 3.0 speed is very fast on computers.”

“NWT, ideal for travel.”
