I tried to find an answer for such question, but I found answers only for not of SSDs (solid-state drive). From what I know SSD disk is much different than old hard disks.
The main problem for me is too much cables inside of my PC, so I put my SSD drive in diagonal position. I'm not sure if there is a risk that disk could slide down to vertical position over time, but for sure it's not placed horizontally. Does diagonal or vertical position affect the lifespan or in any different way can affect a SSD drive?
