Just a heads up that 128 GB iXpand flash drive is on sale for $43.17 on Amazon and Prime Now. This drive will work with iOS devices with lightning port. I've been using one for some time now and works pretty well playing videos, even MKV files using TopReel app (got a free offer within the iXpand app) or share file with VLC. You can use this to backup photos from your phone as well. The killer feature for some may be the encrypted folder on the drive for privacy
