iOS 10.3 will change your iPhone, iPad, and iPod's file system – don't worry, your data is safe!
As solid-state storage has become quite common in computers and mobile devices, Apple built a brand new file system to better take advantage of it. It's called APFS and it was made part of macOS Sierra, in an early form for developers to tinker with. It will eventually become the default macOS file system, and the same will happen with iOS. The update to version 10.3 will migrate your iPhone, iPad, or iPod's file system (as well as the Apple Watch and Apple TV) to APFS.

Thankfully, when the time comes, your data won't be erased in the process. Somehow, Apple has managed to preserve your data from being wiped in the name of a pain-free user experience. However, creating a backup of your data is still highly recommended in case anything goes wrong.

It is unlikely that the switch to APFS will enable major new functionality for users. It could, however, improve device performance thanks to its optimization for solid-state drive storage.

Can someone please explain the difference this will make. Is it just standardization?

No. it changes the filing system of the devices to a system that is more secure, reliable, encrypted, it's designed for the cloud, and it's optimized to be more fast. Plus it's proprietary, and Apple just loves that.

As soon as you said cloud, then it will be much easier for Apple to look at users data. If anyone here thinks that Apple or the government cannot look at your data on the cloud. Then read iCloud license again.

APFS is an entirely new system designed for modern hardware and the cloud, and adds encryption, security, and reliability features that don't exist in Apple's older systems. Inevitably, like every other new file system, APFS will lead to compatibility issues, but Apple is giving itself plenty of time to smooth out the tangles before APFS is released to the public.

Inevitably at least a few will suffer total data loss.

iOS backups arent reliable. I backed up my iPad plenty of time and have the restore fail.

What kind of fail?

You apparently have had every conceivable problem with Apple products (reported or ) that I can think of. Why do you still buy Apple products ? I've backed up five Apple devices in my home, and I have never had an issue restoring - but then again, I haven't had to restore more than two times - none of those were due to a bad update.
