PIODATA iXflash Cube 256GB USB flash drive

256 GB iPhone backup cube

The PIODATA iXflash Cube is a 256 GB USB-C flash drive that backs up every photo and video on an iPhone or iPad automatically while the device charges. It connects through the Lightning or USB-C port and uses the companion app to copy only new files, preserving Live Photos, bursts, dates and locations. The drive creates a separate folder for each person who uses it, so multiple family members can share one cube without mixing libraries. Apple MFi certification guarantees full compatibility with supported iOS and iPadOS devices.

Who this suits and who it does not

This cube is built for iPhone and iPad owners who want a hands-free, cable-connected backup every night without relying on cloud storage or a computer. It works best for people who charge their device regularly and prefer local copies they can restore instantly to a replacement handset. Buyers who need wireless backups, Android support, or direct file access from a Mac or PC should look at other solutions because the cube requires the iOS app and a physical connection to operate.

Capacity and headroom

With 256 GB of space the drive comfortably holds tens of thousands of typical smartphone photos and several hours of 4K video, giving most users months or years of headroom before the cube fills up. The app skips duplicates automatically, so only fresh shots consume new space. Once the 256 GB limit is reached the cube stops accepting new backups until older files are deleted or moved elsewhere, so heavy shooters who capture large bursts or long ProRes clips will eventually need to offload data to a larger archive.
