64 GB USB 3.2 Gen 1 Type-C flash drive

The SanDisk Ultra Slider SDCZ480-064G-G46 provides 64 GB of portable storage for USB Type-C phones, tablets and computers. Its retractable connector protects the port when not in use and a keyring hole allows attachment to bags or keys. Read and write speeds reach 300 MB/s. The drive suits users who need quick file transfers between modern Type-C devices.

Installation and common issues

Plug the drive into any USB Type-C port; no drivers are required on current operating systems. The slider mechanism extends and retracts the connector with one finger. The main risk is forcing the slider if debris blocks the track, which can damage the mechanism. Ensure the host device supports USB 3.2 Gen 1 to achieve the rated transfer rates.

Practical limits of USB 3.2 Gen 1

The interface caps theoretical throughput at 5 Gbps, so real-world speeds typically fall below the 300 MB/s rating. Performance also depends on the host controller, cable quality and file type; many small files transfer more slowly than large sequential ones. The 64 GB capacity fills quickly with high-resolution video or large project folders, and the drive lacks hardware encryption for sensitive data.

Questions about this item

How can I confirm the drive is delivering the advertised 300 MB/s read speed after I plug it in?

Copy a large file to the drive and time the transfer; a sustained rate near 300 MB/s shows the USB 3.2 Gen 1 link is operating at full performance.

What comes in the package and is a Type-A adapter included?

The box contains only the 64 GB Ultra Slider drive with its retractable Type-C connector and a keyring hole; no Type-A adapter or cable is supplied.

Should I choose the 64 GB model or step up to 128 GB or 256 GB for faster speeds?

The 64 GB version is rated at 300 MB/s read and write, while the 128 GB and 256 GB models reach up to 400 MB/s read; pick the larger capacity if you need that extra throughput.
