People say 20% is optimal in computing, but I’m not sure that’s particularly relevant with most iPads. I think it’s to do with swapping, which most do not do. My 64 gb 2018 pro has been on around 62gb for most of its life. Whilst annoying that it’s never got space (64gb is nowhere near enough) - it’s not showing any slowdown issues like a regular computer does. So I’m inclined to say it’s not really an issue with an iPad but ymmv.To keep a iPad fast ?
An SSD should always have some free space to give the controller some space for shuffling things around for wear levelling. How important that is and how much space should be left free depends on factors like how much overprovisioning the SSD does internally and how much data you write to it while using the device. If it's full but the stored data doesn't change much, as is probably more likely on an iPad than a computer, it doesn't matter much.People say 20% is optimal in computing, but I’m not sure that’s particularly relevant with most iPads.

At what percentage did you ever see any slowdown?To keep a iPad fast ?

With smaller capacities, I stick to 20%.
I have iCould Photos set to Download and Keep Original. On older iOS versions, if I didn't have 20% free, the Photos app will complain about not enough free space and recommend switching to Optimize.
Ahh yes that makes senseAn SSD should always have some free space to give the controller some space for shuffling things around for wear levelling.

I only mentioned it because on my 99% full iPad Pro, there are no slow downs, or at least in the manner I would get if my Mac drive were that full.With smaller capacities, I stick to 20%.

Agreed. I have an M1 11 in Pro 256gb that was at 252gb used for months. No noticeable degradation in speed or responsiveness. But it is annoying. Purchased an M1 iPad Pro 12.9 with 2 terabytes so I don’t have that issue any longer. Moved the bulk of my stuff over and am just smooth sailing. iPadOS does a good job managing memory. Maybe other OS’s suffer when memory is near capacity but not iPads, in my experience.People say 20% is optimal in computing, but I’m not sure that’s particularly relevant with most iPads.
