The SanDisk 128GB Ultra Flair USB 3.0 Flash Drive is a sleek, high-performance device designed for users who prioritize speed and durability. With read speeds of up to 150MB/s, it delivers excellent performance for transferring large files like movies or high-resolution images. The durable metal casing adds a premium touch while protecting the device from everyday wear and tear. Additionally, the inclusion of 128-bit AES encryption ensures your private files remain secure.
