How Fusion Drive handles Alias and original files?

Im curious about this. I happen to have 50 documents in my "documents" folder, but I only use 5 of them everyday. So I create 5 Alias for them and save them in a "Alias" folder. Moreover, I put this "Alias" folder in my dock, as a Stack. This provide me quick acess to them

The point is that I click the "alias" everyday, but not the original files. Im sure Fusion Drive is gonna put the "Alias" in the SSD, but will it do too with the original files?

Some of these files are quite big, take time to load, and I would apreciate them in the SSD...

by clicking on the alias, the original file is also accessed. this makes both accessed at the same frequency and therefore be a good candidate for getting into the SSD, in theory of course.

did Apple release a whitepaper for Fusion Drive? I'm interested to see their algorithm.

you might want to explain why it's a file instead of just telling someone that it is. it sounds like you are trying to be superior than others.

... like everything in Unix is a file, just different types, right?

Genuine question, can you prove this, I am not saying you are not right but I believe it's just a link in the directory like a folder.
I say this because if you try to open the alias or get info on it it's the original which shows up, not the alias.
A file is in the file structure, an alias is to my knowledge not and as I said before is in the directory.

Is it?
Is a reference in the directory a file or a menu item a file?

To further explain is a line in a text file a file?


BTW, I am not offended by sidewinder, I just want him to explain why he think it's a file while I think it is not.

You sure about that? Because that's the opposite of what really happens…

Might wanna rethink that logic there.

Yeah, I tried with making an alias and a symlink, an alias is a fair bit more than the original while a symlink only is 4 Kb.

Guess I am wrong here, did not look at the difference in size of original and alias/symlink.
