Score: 90/100Rankings

The SanDisk 128 GB Ultra USB 3.0 flash drive combines high capacity with fast read speeds and built-in encryption, aimed at everyday users needing portable storage. Its retractable connector and 5-year warranty are positives, while slower write performance and a lack of an LED are notable drawbacks.

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.
