One note:
I am not talking about 4K Clusters,
I am talking about 4K Aligned Partitioning..
That's what you need on SSDs (or on Flash in general, e.g. USB Flash Drive, microSD/SD cards, etc),
or else, every cluster that is written, has to be written twice, which is slower and wears your storage device.
I think I know what you meant. 4k has been used on hard drives about the same time achi became a thing. In around 2010 or something. Even before SSD became mainstream. The thing is, I don't think it is a thing for flashdrives and and sd cards. When you plug those the OS automatically knows they're not hard drives or SSD. So I don't know if they will make a 4k aligned partition for them. I never heard there was a need for 4k alignment for flash drives or sd cards. I think that 4k in combination with sata achi provided a slight speed boost. I could be wrong but that's how I see it.
