What are the SSD and NVMe pre install procedures

TRIM - I've been doing some research on these subjects and from other post in this forum it appears that Kubuntu does include trim

Over-Provisioning -

I found an interesting article by Seagate about over provisioning a SSD. https://www.seagate.com/tech-insights/ssd-over-provisioning-benefits-master-ti/

If I read that correctly, it appears that manufacturers build in 7% over provisioning by default due to the difference in GB vs GiB (Note the lower case i) On top of that, it appears that any free space on your SSD will be used as 'dynamic' over-provsioning. So although setting aside additional unallocated space for over-provisioning would increase performance when your drive is full by prohibiting you from truly filling your ssd with data. It seems to me that it would not make a difference if you have any empty space on the drive since that would be used for dynamic over provisioning anyway. I think that would include formatted space that is empty too. At least thats how I understand it. So it appears to me it might be helpful in some cases if your run your SSD at high capacity, but not really necessary. Let me know if its something different.

What are the best recommended procedures for installing Kubuntu on and SSD or NVMe M.2 drive?

TRIM - Does Kubuntu set trim automatically or will I need to set trim?

Alignment - In the past I followed some threads about putting 1MB of unallocated space at the beginning of the SSD to account for alignment of the drive. I have also seen comments about using 3MB for a NVMe drive. Does this need to be done?

Overprovisioning - Some people say you need 10% unallocated space at the end of the drive to account for over provisioning. Do I need to do this?
