These are super handy- high speed flash drives with the usual USB connector but ALSO the new type USB-C. So in the case of new macs especially - where you ONLY have USB-C and still want a handy backup and transfer device, this is your only man.
FURTHER to this though, is that it also clips in to any iPhone or Android phone that has USB-C (iPhone 15 and 16 and newre Android phones of the last 3 years) and allows you to backup your photos easily and also transfer them to any other computer of deivce.
