Score: 76/100
Vansuny 64GB USB Flash Drive
Score: 58/100Rankings

The SanDisk 128 GB Ultra Dual Drive Luxe combines a premium all-metal body with dual USB-C/USB-A connectors and a swivel mechanism, delivering solid read performance and a keyring-ready design. However, its write speeds are modest, it lacks built-in encryption, and it may heat up under heavy use.

The Vansuny 64 GB USB 3.0 drive combines a rugged all-metal body with waterproof, dust-proof and shock-proof ratings, making it ideal for harsh environments. Real-world transfer speeds fall short of the advertised figures, and the lack of an LED may be a minor inconvenience.

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

Professional reviewers highlight the drive's premium metal construction, dual-connector versatility and the convenience of eliminating adapters, but criticize the misleading 400 MB/s claim and the absence of built-in security features.
Everyday users praise the drive's solid build, keyring design and seamless file transfers between phones and computers, especially for backing up photos on the go. Recurring complaints focus on the drive heating up during large transfers, slower-than-expected write speeds, lack of encryption, and a swivel hinge that can become loose over time.

“Absolutely amazing... I haven't seen such a stick till now.”

“Perfect for photos”

“No cap to lose”



Reviewers commend the metal housing and verified waterproof claim, noting real-world read speeds around 35 MB/s and write speeds of 28-30 MB/s, while pointing out the gap between advertised and actual performance.
Users love the durability and compact size, but often mention slower-than-advertised speeds and the need to dry the drive after water exposure.
