It's the same exact thing for pretty much any kind of drive... including hard drives. The way you phrased it (to me) seemed like you meant this behavior was unique to SSDs. If that isn't the case, I take back what I said.
No I didn't mean it in the context of SSD's alone. I was only trying to be a help to him in a generic way which wasn't too technical for him. I didn't want to bog him down with a lot of technical details that weren't necessary for him to accomplish his goal.
Apologies if I wasn't clear in my writings.
