Deleting stuff off your iOS device can get really annoying, but there is something you can do to remedy this by improving the internal storage of your iPhone or iPad with a 3-in-1 iOS USB flash drive solution like the JumpDrive c25i by Lexar.
The Lexar JumpDrive C25i expands the memory of your iPhone or iPad while providing portable storage on the go. The JumpDrive C25i flash drive comes in three sizes: 128GB, 64Gb and 32GB.
The one you see pictured is the 32GB version of the JumpDrive C25i which can supply USB 3.0 read speed up to 115 megabytes per second (980 megabits per second) perfect for quickly loading and reading information/data from the drive. The USB 3.0 write speed when copying data from the JumpDrive C25i to a folder is around 20 megabytes per second (160 megabits per second).
A nifty feature you get with the Lexar JumpDrive C25i flash drive is automatic camera roll backup of all pictures taken with the camera, as well as contact files. To use the automatic camera roll backup facility you simply download the Lexar Media Manager app, available on the App Store. The Lexar Media Manager app is compatible with iPhone 5/5s/5c, iPhone 6/6s/6s Plus, iPhone 7/7 Plus, iPhone SE, iPad mini 2/3/4, iPad 4, iPad Air 1/2, iPad Pro 9.7 inch/12.9 inch, and iPod touch (sixth generation).
As far as performance, using CrystalDiskMark disk benchmarking utility to test the read and write speeds on a Windows 7 computer with Intel Core i7 3.4 GHz processor, the JumpDrive C25i performs pretty well with a sequential read/write of 109.3/19.9 MBps and a 4K random write speed of 2.1 MBps that shows how quickly the JumpDrive C25i can write multiple small files.
