Product details
Same plug-and-stay trick as its bigger sibling, sized for the everyday carry role: 256GB that lives permanently in a laptop, dock, or mini PC port and reads at up to 400MB/s over USB 3.2 Gen 1. Use it as a dedicated clips drive for your streaming setup, a portable installs folder, or overflow storage that never sticks out far enough to get snapped. Five-year warranty and a body measured in millimeters — storage that simply stays put.
Searches that match this SKU: "256GB low profile flash drive," "flush USB drive," "USB drive for Tesla/dashcam music," and "leave-in laptop storage." The 256GB tier is the everyday version of the Ultra Fit idea: a quarter-terabyte that stays resident in one machine — a dedicated drive for stream recordings, a music library for a car or console USB-A port, or document overflow on a work laptop that never has free space.
SanDisk specifies up to 400MB/s reads for the 128GB–2TB sizes of this line on USB 3.2 Gen 1, far beyond what media playback or game installs need, and the near-flush body means a laptop can go in and out of a bag with the drive installed. 5-year limited warranty.
