Is a junction point effective in decreasing write cycles of SSD?

Question

Since SSDs have a limited life cycle and I have one experience of an SSD crash, I decided to be proactive and avoid writes.

I moved all my data to an HDD.

I understood from various people that indexing does a lot of writes. I know that Adobe Premiere also does.

So I moved my Programdata folder and Users folder to an HDD from my SSD. (Used robocopy from resuce disk cmd). All is well.

So, when windows sees a junction point will data be written directly to the destination (HDD) or will it be first written to the SSD and then another process will write it to the HDD?

I feel it will directly go to D Drive, still wanted to confirm.

Answer 1

You can think of a junction in NTFS as a wormhole. Any read or write instructions through that point will be redirected to the true location at the other end.

So there may be a very small amount of activity from the SSD where it looks up the correct end point but that's it.
