Capacity and connector

The SanDisk Ultra Slider is a 256GB USB flash drive with a retractable Type-C connector. It suits users who move files between modern phones, tablets and laptops that only offer USB-C ports. The compact slider design protects the plug when not in use and includes a keyring hole for easy carrying.

USB 3.2 Gen 1 practical limits

The drive uses the USB 3.2 Gen 1 interface, also referred to as USB 3.1 in the specifications. This standard caps theoretical throughput at 5Gbps, so real-world transfer rates are limited by the host controller, cable quality and file types. Performance will vary across devices and workloads.

256GB capacity and headroom

The 256GB capacity provides ample space for large photo libraries, video projects and document backups. Sequential read speeds reach up to 400MB/s, allowing quick access to sizable files. Write speeds are lower, so sustained writes of very large datasets will take longer. Actual user capacity is less than the decimal figure.
