What to know before buying
Listing details to confirm
Mobile file transfer requires a USB-C device with USB On-The-Go (OTG) support. Automatic backup requires downloading and setting up the SanDisk Memory Zone app. The up-to-400MB/s figure is a read-speed claim based on internal testing and varies with host device, usage conditions, capacity and other factors. The listing’s general details label 400 as write speed, while its title and feature text claim up to 400MB/s read speed, so treat read speed as the stated claim and do not infer a write speed.
Who is it for?
A good fit for
- People who want one flash drive to move files between compatible USB-C phones or tablets and USB-A computers.
- Travellers who need compact removable storage for photos and files, subject to mobile-device OTG support.
Less suited to
- Buyers who need confirmed write-speed performance or a guaranteed transfer rate across all devices.
- Mobile-device users whose USB-C port does not support OTG.
