Score: 39/100
PNY Turbo Attaché 3 128GB 5-pack
Score: 90/100Rankings
PNY's Turbo Attaché 3 128 GB 5-pack offers very fast 140 MB/s reads, a cap-less sliding collar, and an activity LED in a lightweight plastic body, providing good value for casual users, but inconsistent write speeds and a stiff slider can be frustrating.
The Ultra Dual Drive 128 GB offers a sturdy metal body with both USB-A and USB-C connectors, delivering fast reads and a convenient keyring loop. Lack of native encryption and modest write speeds make it better suited for occasional transfers than heavy-write tasks.
