While we're on the topic PCIe lanes and SSDs, I've been looking into some way of usiing old NVME SSDs when they get replaced by bigger ones. I don't really want to have a stack of little m.2 USB boxes. There are some PCIe adapter boards that take two or more SSDs but what isn't clear to me is if those cards can work in the typically free x1 PCIe slot, if the cards are x4 or x8 and drives are x4? > Yes.

I have to say I was quite disappointed when I cloned a 1TB SSD to a 2TB one, average speed wasn't much higher than writing to an HD. I don't remember what the target drive was though. Since I don't intend to make a habit of this, no big deal, but I wonder what kind of write speed one could expect in a sustained write of 1TB?
